Lithium battery "security risk"

Now, look a little as long as electronic products, you will find traces of lithium batteries almost everywhere. Large laptop, digital cameras, small mobile phone, digital cameras, mp3. At the pre-lithium batteries, electronic products are used in Ni-Cd or Ni-Cd Ni-MH battery. Because of smaller, lighter weight and do not hate the memory effect, lithium batteries to become the new darling of the market has led to a portable electronic products, a revolution, many of energy will be concentrated in very small space. Despite these excellent characteristics, lithium batteries, there are security risks. If the charging of excessive, or similar short-circuit such a failure, sealed in the battery on the chemical substances transformed into a flammable dangerous goods. These flammable chemicals caught fire at once, it probably happened a "blast." These flammable materials what is it? From the laptop manufacturers and battery manufacturers to launch a new battery of view, directed at the lithium-lithium dell laptop battery . Lithium in the periodic table of the second cycle, the first main group, with the active metal sodium, potassium and family. The group elements are the common characteristics of a very lively encounter water, air and other substances that can react quickly, and even cause an explosion. However, lithium batteries are not lithium metal, but the lithium-ion (Li +). Lithium-ion rechargeable lithium battery in the discharge process does not produce lithium: When the battery charge, the cathode to the anode of lithium-ion movement; and discharge, the lithium-ion back to the cathode to provide energy. Although not flammable lithium-ion materials, but the formation of lithium-ion lithium electrolyte salts is genuine flammable liquids. This is also determined to use Sony lithium-ion lithium polymer instead of the original, which exist in the form of colloid, not the formation of flammable lithium electrolyte salts. Rechargeable lithium dell 310-6321 at the completion of the cathode because of the loss of the majority of lithium-ion has become very unstable and gradually accumulated heat, the temperature sufficient to decompose and release oxygen cathode. In addition, the internal lithium batteries have graphite as the anode material, the main component of carbon and other flammable substances to the entire Li-ion battery's chemical composition is very unsafe. The explosion caused a fire last year, more than the case of the murderer, it is some fine particles of metal - nickel. These cells at the production process into a "killer", after the completion of the charge, through the insulating layer of the cathode to the instability and crystallization of the mobile, resulting in short-circuit, resulting in local overheating dell 310-6322, lithium batteries ignited graphite, oxygen, lithium salt type of electrolyte, the battery eventually lead to a fire and explosion.

The concept of balanced battery technology and application

To the equipment in order to provide sufficient voltage, lithium battery pack is usually made by a number of batteries in series, but if the battery capacity mismatch between the impact will be the capacity of the entire battery pack. To this end, we lost the need for a balanced allocation of the battery. This article discusses the concept of balanced battery and some attention. Li-ion battery pack is usually one or more batteries in parallel, each battery pack by 3-4 in series constitute a battery. This combination can satisfy the laptop at the same time, medical equipment, testing equipment and industrial applications of the voltage and power requirements. However, the general configuration of this application does not usually exert their maximum effect, because if the capacity of a battery in series with other batteries do not match will reduce the capacity of the Toshiba laptop battery pack. Battery capacity does not match, including state-of-charge (SOC) and capacity mismatch / energy (C / E) mismatch. In both cases, the total capacity of the battery pack can only reach the capacity of the weakest battery. In most cases, the mismatch caused by the battery of the reasons for process control and testing are imperfect means, rather than lithium-ion changes in their chemical properties. Prismatic lithium batteries (LiIonprismaticcell) required more time in the production of mechanical stress, the battery is more prone to the difference between. In addition, the lithium-ion polymer toshiba pa2487u battery will be because the introduction of new technology and the emergence of differences between the battery. Balanced use of the battery SOC and treatment techniques to address C / E mismatch problem, thereby improving the tandem performance of lithium-ion battery pack. Through the initial adjustment process in a balanced treatment of the toshiba pa3107u-1brs cells can be corrected mismatch problem, since only in the charging process can be balanced, and the C / E mismatch must be sufficient discharge to a balanced process. Even though a battery manufacturer for their products in terms of possible defect rate is very low, but in order to avoid too short battery life, we still have the need for further quality assurance. The definition of a balanced battery Working voltage of 6V or more portable devices powered toshiba pa3383u-1brs pack used in series, in which case the total battery pack voltage of the battery voltage of the series and. Portable computer from the battery pack is usually three or four batteries together in series, nominal voltage of 10.8V or 14.4V. In most such applications, a single series battery pack can not provide the energy needed. The biggest battery current (such as 18650) provides 2000mAh (milliamp hours) of energy, and the computer required 50-60Whr (5000-6000mAh) energy, it must give each series of three battery cells in parallel. Battery balance refers to the series are different toshiba pa3384u-1brs pack battery (or battery) Use of differential current. Battery packs in series for each of the current battery is the same as usual, it is necessary to increase the extra battery pack and circuit components to achieve a balanced battery. Only when the battery pack in the battery are connected in series, at the same time series equal to or greater than the three-tier battery when the battery will consider the balance. When the battery pack to meet all batteries have the following two conditions, we achieve a balanced battery: 1. If all the capacity of the toshiba pa3285u-1brs the same as when their relative status as charging the battery when the balanced implementation. SOC is usually the current capacity and nominal capacity expressed as a percentage, therefore, open circuit voltage (OCV) can be used as a measure of SOC. If a battery pack is not balanced all of the battery can be recharged through the differential reach full capacity (equilibrium point), they will be able to carry out the normal charge and discharge without any additional adjustment, this adjustment is usually a one-off. Users when using the new battery, it normally takes a long time called for charging batteries, in fact this process, including a full release - charge. So that the process to minimize the load and the longest battery and reduce battery requirements of a balanced circuit. 2. If the toshiba pa3191u-1brs capacity is different from the same when the SOC that they are balanced. However, SOC is a relative value, the absolute value of the capacity of each cell are different. Different in order to make the battery capacity SOC the same for each of the battery charge and discharge in series must be used when the difference current. Normal charge and discharge time of the initial charge and discharge more quickly, and required greater current. When the battery pack in the satellite 2100 battery is not balanced, it will reduce the available capacity, serial battery pack in the battery capacity will determine the minimum of the total capacity battery pack. Imbalance in the battery pack, a battery or some other battery will still charge the maximum capacity has been achieved. In the discharge when the battery is not fully charged battery will be released than other electric end, the battery pack due to insufficient voltage to the supply of electricity in advance. Typically, the satellite a65 series capacity of the differences between the less than 3%. If the lithium battery packs in series to a battery of sub-standard, or placed in the package too long ago, after the electricity at a voltage difference of up to 150mV, so that the total capacity of the battery pack dropped 13-18%. SOC balanced treatment If the battery pack in the battery capacity of all the same, we will deal with the use of SOC balance. When all the battery SOC value at the same time we believe that the satellite a60-662 battery are balanced. A single battery charge status is defined as: SOC = C / CTOTAL% The capacity of a single cell is defined as: C = (i × t) mAh In order to determine the capacity of a satellite 1900 battery , we have the battery fully discharge and then recharge, and recharge in the process of current measurement at different time until it reaches the open circuit voltage of 4.20V. The best performance of the battery status in the SOC for the 100%, SOC 50% of the OCV voltage is often referred to as VMID, its typical value of 3.67V. In order to give a different battery capacity so that they achieve the same SOC, to ask some battery charge / discharge capacity than many other tecra 9100 battery, which must use the current differential. We will call this process of capacity / energy maximization. Capacity / energy to maximize Capacity / energy to maximize the battery pack means that all the series is set to the same battery SOC, even if they are different capacity. Time management in all SOC, the battery pack to maximize the output energy. In order to maximize the output energy, all the batteries have to be full of electricity. That is, all the battery SOC must be 100%. If the battery capacity is different from a number of tecra 9000 battery charge / discharge the battery will be more than any other. For example, suppose there is a battery pack of three batteries in series, C1> C2 = C3. Balance of the battery packs are the only way to give a higher capacity battery (C1) to impose a differential charge current. Discharge the battery pack must also be the case, otherwise, when the battery capacity to meet the minimum turn-off voltage, the entire tecra 8100 battery pack will stop the discharge, while remaining battery capacity of the other, thus reduce the total capacity. The long run, the capacity of the smallest battery performance will be a recession than any other battery faster, go through a number of charge / discharge cycle will accelerate the loss of capacity. Through the matching series battery voltage, high-capacity toshiba pa3356u-1brs will draw more current. Discharge when consumed through a balanced number of extra voltage, in the final when all batteries have reached 0SOC when obtained from the battery pack relative to the total energy balance will increase the former. Usually cylindrical lithium-ion battery (cylindricalcell) are usually of better quality control, battery capacity difference of no more than ± 3%. Basically, more precise input capacity, the difference does not exceed some mAs (milliampere seconds). Therefore, the toshiba pa3250u-1brs capacity is also the basic accuracy of the absolute value, SOC at the difference within a few percentage points.

Note the use of battery charging points

1, battery charging 1.1 Charging temperature Please at 0 ° C to 40 ° C ambient temperature process carried out under the battery. Charging process, the ambient temperature will affect the acer laptop battery charging efficiency, so at 10 ° C to 30 ° C under the charge of the charge to reach the best efficiency. Below 0 ° C under the charge, the battery inside the gas absorption reaction will not be normal, resulting in acer btp-43d1 with hypertension, which will lead to the battery to start the release of the valve of the alkaline gas, eventually resulting in declining battery performance. At 40 ° C higher than that under the charge, the battery charging efficiency will drop, battery charging will shorten the travelmate 220 battery is not fully working hours, and it will result in leaking alkaline batteries. 1.2 Parallel battery charging In the design of the acer btp-58a1 charge when necessary to carry out parallel to be very wary! In this case, please contact our technical support can be detailed. 1.3 Reverse charging No reverse battery charge! Reverse charging of the ace btp-60a1 cell internal pressure will cause a sharp increase, which will start the exhaust valve to release the battery alkaline electrolyte, resulting in the rapid decline in battery performance, battery swelling will appear in the situation and battery rupture. 1.4 Overcharge Should avoid over charging, over-repeated charge will cause the travelmate 240 series battery performance. (Overcharge refers to electricity are already filling enough to continue charging the battery) 1.5 Fast Charge When rapid charging of ace btp-52ew, use a specific charger (or the company recommended charging method), and in accordance with the right procedures. Trickle charge of 1.6 (for charging) Do not use nickel-metal hydride ace btp-63d1 trickle charge. However, the use of fast charge on the battery can be used after 0.033CmA to supplement 0.05CmA trickle charge. At the same time to avoid the charge by way of trickle-off charge, which will damage the characteristics of the battery should be used to control the charging time of the timer. Notes: "CmA" In the process of charging and discharging, CmA is a specified size and that the acer batcl50l current rated capacity of the value, "C" refers to the rated capacity of the battery. For example: on the rated capacity of 1500mAh battery 0.033CmA, this value of 0.033 indicated good 1500 (or 1500 divided by 30), that is 50mA.

Batteries and components enterprises are facing reshuffle

In the whole industrial chain of photovoltaic solar power, solar cells and components in a central position. In recent years, a large number of our country in the introduction of foreign advanced equipment, high-grade,laptop battery,at the same time have a single crystal silicon, polycrystalline silicon, amorphous silicon, such as species of batteries and components, solar photovoltaic cells and components of the production is rising year after year. In 2007, China's production of photovoltaic components for more than 1000MW, the first production has been largest in the world, more than Japan, the United States and other countries.
However, as the lower reaches of the industrial chain business aspect of solar power components an awkward position: the minimum profit margin, the greatest risk. According to a solar power not to be named Assistant General Manager component companies, the current components of the net profit of photovoltaic solar power rate is only about 5%. While in the international financial crisis,apple laptop battery, the beginning price of polysilicon have fallen sharply, and corporate profits have begun to gradually upgrade, but the lower reaches of the solar cell system, the shrinking demand, leading to production decline, the profits of enterprises have begun to decline.
Another component of the plight of business at its greatest risk. There is a potential trade rules, and that is the warranty period of solar power components at 20 years ~ 25 years,apple a1175, but we know that not only uses solar power silicon material components, but also use different types of chemical materials, the durability of each material period are different, how to ensure that all of the material to achieve the 20 years to 25 years of shelf life, this is a big problem.
Solar power components vis-à-vis enterprises, apple a1185 , enterprises of solar cells are relatively better at. First, the solar cell business relative to higher profit margins, it is up to 15%. Second, the solar cells is crystalline silicon material, which is relatively small risk. Components because of the technical content of cells is relatively lower, so the solar cells of domestic enterprises will not only produce solar cells and the production of components, which improve corporate profits and reduce risk is undoubtedly of great role.
The current international financial crisis was only the beginning, the situation in 2009 will be the most severe year. We can see that,apple m9324, in the face of the international financial crisis, most countries focus on building up infrastructure, stimulating domestic demand for solar energy photovoltaic industry is not too positive. While photovoltaic solar power industry over the past few years has maintained rapid growth, from 2001 to 2007, solar cell production in the year 150% compound growth rate, but in 2009 the market will enter a difficult period.
Batteries and solar power components How to deal with the current international financial crisis? One effort to improve the conversion efficiency of solar cells. We have seen our country photovoltaic cells and solar power technology and equipment components of a great development and progress, photoelectric conversion efficiency from the original 10% ~ 12% to 17% ~ 18%. It is reported that Nanjing has been the successful development of electric current from an average of 17.5 percent conversion efficiency of the SE up to the battery as well as 19% of the N-type apple m8403.
Second, the extension of industrial chain, reduce business risk, improve profits. China's solar cells will produce the basic components of enterprises, and gradually begin to penetrate the production of crystalline silicon, the industry chain to penetrate the most upstream. Suntech is the first production of crystalline silicon solar cells and modules have already infiltrated the high-purity polycrystalline silicon, silicon thin-film solar cells and solar photovoltaic power generation systems. Linyang energy from solar cells and components into the silicon material, apple m7318, solar photovoltaic power generation systems in areas such as ultra-day in Shanghai have begun to put the solar power industry chain to penetrate the upper reaches.
However, because of our country and photovoltaic solar cells in order to export-oriented components, thus the current industry components over the infiltration of the industry chain mainly travel to a temporary facing downstream market penetration of the problem could not be opened. However, with the country of the importance of energy-saving emission reduction,apple powerbook g3, the PV market in China will also open, which also put a lot of penetration to the lower reaches as a technical reserve, ready to be launched.
With the sophisticated technology of photovoltaic, as well as the increasingly serious energy shortage problem, the application of photovoltaic technology are unlimited prospects will certainly bright. While the international financial crisis, the more cold photovoltaic enterprises,apple powerbook g4, but for the entire industry, is also a reshuffle is conducive to rational norms of the market gradually. After 2009, the "winter", perhaps next year, solar energy photovoltaic industry will usher in Sunny.

Automotive battery's market competition is very strong in South Korea and Japan

Recently, the people more and more worried about the world oil market. The international community has been committed to efforts to reduce greenhouse gas emissions, and almost all industries are concerned about the second-generation mobile battery development.
Assembly has a mixture of mobile ibm laptop battery electric vehicles (HEV) by the use of fossil fuels and greenhouse gas emissions can be reduced more than 30%. The United States and Europe and other developed countries are trying to popularize this kind of future vehicles. Built-in hybrid electric vehicles (PHEV) and electrical vehicle (EV) will become the next generation of hybrid electric vehicles, the main characters. In the social, economic and environmental aspects, the popularity of these two types of motor vehicles is much higher than the general effect of the hybrid electric vehicles. So now is the developed countries to these two types of automotive research and development as the center, hoping to achieve commercialization. (Built-in hybrid electric vehicles are referred to at the time of parking can be recharged through the socket of the car.)
Japan's Toyota and Honda dominate the hybrid electric vehicles and related technologies. The two companies in the world market share of over 85% IBM thinkpad t40 battery.
In hybrid electric vehicles used on the majority of nickel-hydrogen batteries are almost manufactured by Japanese companies. The lithium battery as a high-profile second-generation mobile batteries, compared with the nickel-metal hydride battery unit volume and unit weight of the energy density and higher output power density. However, because of security issues as well as price, automobile production has not yet been able to adopt a large-scale lithium thinkpad a21m battery.
Toyota Motor Corporation and other Japanese companies will be announced at the 2008 Hybrid Electric Vehicle on carrying lithium batteries. However, because of security issues, lithium cell vehicles listed will be postponed. The Hyundai Motor Company announced plans in 2009 will begin with large-scale production of lithium-ion thinkpad a20m battery hybrid electric vehicles. In view of this, the world's automotive industry has entered the competition cars lithium battery time.
Because of the development of the car battery used in mobile case will take a very long, so automobile production enterprises and business cooperation between the battery is the most important. Hyundai Motor and LG Chemical Company has joint development co-operation more than five years. July 2009 upcoming Hyundai Elantra LPG Hybrid Electric Vehicle. In addition, LG Chemical Co., Ltd. has become common in the United States built-in hybrid electric vehicle thinkpad a20 battery used in the development partners, the two companies are to proceed with joint development.
In today's world IT industry and automation are the time, light and easy to carry the commercialization of lithium batteries is against this backdrop that appears. In our daily life in the common automation products such as mobile phone, laptop, PMP, MP3, the lithium IBM 02k7054 as a source of energy has been widely used. In Korea, LG Chemical and Samsung SDI start in 2000 from large-scale production of lithium batteries, with Japan lagging behind compared to a full 10 years.
At Japanese companies had been monopolized by the lithium IBM 02k6928 market, Korean companies with unique design of lithium battery technology and manufacturing technology has won the competitive edge. According to projections, in 2008 in Korea on the global market share has reached 30%.

Japan and South Korea are the key technical leader for battery electric vehicles

Electric car craze in full swing, but also because it appears that the Detroit auto show is not the end of the cool! Electric car one of the rechargeable batteries used in electric vehicles is the key to the development of technology. To this end, some motor vehicle dealers in Japan have the battery technology with the traditional strong vendor or co-operation or participation, such as Toyota and Matsushita old partner, Nissan and NEC to develop strategies such as auto-rechargeable batteries or rechargeable batteries. Then, at the world's major car manufacturers have to develop electric cars as part of the company's current strategy for the future development of the global automotive battery technology and how this pattern? How it will affect the future of the global car industry map changes? One of the most concern to us BYD-iron battery technology in a kind of position do? Let us take a look at the electric vehicle industry, senior analyst at the HUNTET HSU-depth analysis and introduction. Automotive Electronics is the trend of broad prospects for electric cars Universal Group of the United States in 2008 by a hundred years at plants Renqing moment, the formal launch of mass production version of Chevrolet Volt to open a new era of electric vehicles. With consumers growing awareness of environmental protection, the same general group of the German brand Opel also announced at the Geneva Motor Show in 2009, launched "Ampera" the new electric cars. Used four five-set Ampera, Chevrolet Volt and in fact there is a considerable degree of similarity: In addition to the headlights swept the long and narrow lines of the same things, Ampera narrow use of the water tank shields, while the lower edge of the headlights also add similar Flextreme concept car with the factory intake gate design, a dynamic avant-garde design. Aspects of power, Ampera with common power system Voltec Group, the owner may, by a 230V AC power for charging Li-ion sony laptop battery module in the case of full electricity, Ampera available distance range of 60 kilometers; the way those who are driving farther, Ampera by small internal combustion engine with the engine, but also continued to produce electricity in order to provide more long-distance capacity of endurance.
As the capital market on the first group of electric vehicle industry one of the researchers, I have the opportunity to use the last of the technical bottlenecks in the electric car to do a preliminary analysis. The introduction of electric vehicles will be my key to the core components: auto-rechargeable (secondary) sony pcga-bp1n ! Vehicle because of the rapid development of electronic applications, automobiles are no longer traditional mechanical products, but has all the modern technology in an intelligent, integrated optoelectronics, semiconductors, electronics, communications technology, integrated platform. 2004, each new electronic products in 1518 U.S. dollars spent, but also someone with the mechanical and electrical integration estimates the continuous advancement of technology, the future costs of electronic products is expected to reach 40% of the cost of vehicles. Corresponds to a high degree of electronic vehicle trends, the automobile industry to promote 42V or 42V/14V power system has also gradually speed up. Automotive electronic systems demand for electricity between now and year 2030 will maintain a 5 ~ 8% of the rate of growth, at transitional phase 42V/14V power system from generation to generation is expected to become the new standard vehicle power system. At present, foreign advanced car electronics required more than 2000 of the wiring harness, various control devices to connect more than 4000 points, the total length of wiring harness more than 4000 meters,sony pcga-bp2nx, the weight of more than 40 kilograms. The future after the switch to 42V power system, the existing cross-sectional area of wire from the mainstream of 0.5 ~ 1.5mm reduced to 0.35mm. Voltage improve vehicle performance benefits at: (1) the same power, the wire current to flow through small, cost of each and every wire ohmic loss, fuel consumption could be reduced by 10 ~ 20%; (2) saved by the wire Spaces can be added to the new electronic system; (3) the use of aluminum instead of copper wire, to a more narrow size; (4) in line with the needs of the development of hybrid vehicles. With the vehicles 42V power system time on the energy storage media / battery demand will further increase. Since 1800 Alessandro Volta invented the world's first battery in 1859 Gaston Plante invented the lead-acid rechargeable battery, the engineers never stopped looking for ways to better the efforts of energy storage. Chemical batteries or rechargeable batteries based on the characteristics, are divided into "a cell" and "secondary battery" two broad categories. Including a battery on the market common alkaline batteries, mercury batteries, and manganese dry batteries, silver oxide sony pcga-bp2r, lithium batteries, such as air batteries, rechargeable batteries for portable electronic products is currently the bulk of applications, including lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries and lithium-ion batteries, lithium polymer batteries and super capacitors. Lithium-ion batteries in 1990 to come out and finish the business in 1991, and the use of gel polymer electrolyte for polymer electrolyte membrane and the lithium-ion batteries were introduced in 1995 and commercialized in 1999. But lithium-ion battery package has security concerns there.
To explore future trends in automotive batteries, starting from two directions: a function of charge and discharge rechargeable battery power and the provision of the electrochemical cell, which the mainstream for the past lead-acid batteries, but because of hybrid-type of secondary sony pcga-bp2s significantly improve the performance requirements. Ni-MH (nickel-metal hydride batteries) because of excellent value for money and more security (as opposed to lithium-ion batteries) and has high energy density, power density, rapid charge-discharge, long cycle life and no memory effect, no pollution, can be maintenance-free, the use of fully characterized, is known as "green battery." Ni-MH batteries are the energy density of nickel-cadmium battery 1.5 to 2 times charge-discharge without memory effect, low temperature characteristics of good, overall performance is superior to nickel-cadmium batteries, nickel-cadmium batteries and no batteries to deal with the problem. At present, the majority of the market are hybrid-type Ni-MH battery selection as a storage medium for energy recovery. The future if the cost of lithium batteries and vehicle safety performance in line with the requirements of nickel-hydrogen batteries to gradually replace the trend of a few can be identified.
Much hope that the industry can not wait to be able to study the dismantling BYD F3DM At present, the global lithium-ion / Li-polymer sony pcga-bp2t market vendors concentrated in the Asian region, Japan, Korea, Chinese mainland and China Taiwan manufacturers sub-regional food market pie, one of grasp the technological superiority of Japanese firms to occupy 80-90% of the market share , standing hegemony. Japanese firms to develop lithium-ion / Li-polymer of the oldest, technology and the stability of quality at the industry leading technology from Japan to copy the South Korean manufacturers are behind because there is Samsung, LG and other companies to support, some good score. Lithium-ion battery cathode mainly by internal, cathode, electrolyte and membrane composition, due to positive and negative electrode and electrolyte materials and called different names in different. Currently on the market for lithium-ion battery cathode material is lithium cobalt oxide (LiCoO2), the other a small number have used lithium manganese oxide (LiMn2O4) and lithium nickel oxide (LiNiO2) cathode materials for lithium-ion batteries, the two have been at hand-held electronic products in a very universal. So far, not been able to iron lithium battery of large-scale commercial Lithium-iron sony pcga-bp2v has a behind the back of the complex patent disputes Is apart from lithium-ion batteries, there is no other battery technology of electric vehicles can meet the needs of the market? The answer to this question is also negative, including the depot into a large number of Honda fuel cell R & D resources, as well as BMW have experimented with the "super capacitor" technology are viable options, the latter with the FIA is to vigorously promote the F1 track in the kinetic energy recovery system (Kinetic Energy Recovery Systems, referred to as KERS) is closely related to the future, I also detailed description of the author.

Battery industry:the gap between technology and manufacturing

Guotai Junan Wang Zhen
Investment Highlights: "Look the more the less know how to" no doubt we are at the process of writing this report the most experience. We have been thinking, what is the strength of the battery industry to promote development? We believe that every time the application of new materials so that battery performance has been a qualitative leap, each positive and negative material or electrolyte batteries also contributed to the improvement of the quality of the rate must be improved.
History of the development of batteries, it is a history of material progress of science and technology. Process Improvement quantitative battery, new materials of the invention to change the battery. It is foreseeable that the use of lithium-containing conductor material elements (ionic compounds, polymers) as the electrode materials are the best choice for high-energy battery, but, many elements of the discovery of compounds for lithium-ion materials technology necessary to continue to progress.
Enhance the energy storage potential, improve energy density, this hp laptop battery technology is always evolving the concept of one of the most direct. However, the perfect person does not yet exist, especially in high power and high energy are difficult to exclusive. Moreover, we also found that different products with the diverse needs of the battery. Thus, the development of pb994a , pb991a materials is also diversified.
Compare the appearance of performance, security, price, life is essential to consider the indicators, which determines whether the wider application of certain types of batteries. Because, lithium-ion battery provides superior performance, different cathode materials for lithium-ion 398876-001 . pb992a to meet the cost difference between the market demand for different applications, thus, the formation of lithium-ion batteries of other types of battery almost full substitution trend.
Even though, we have the impression that battery manufacturers are labor-intensive, but from the battery industry chain, the same are technology-intensive, especially in resource extraction processing and battery Preparation Materials Materials more disciplines involved. Through the icon of lead-acid batteries, nickel metal hydride batteries, lithium-ion hp ev087aa , hp ex942aa manufacturing process flow of the main aspect, we point out that the domestic battery industry development direction and technical bottlenecks.
At battery industrialization of China and Japan, the United States there is a considerable gap, which ultimately can be reflected in the materials technology industrialization gap up at home and abroad. In our view, to rely on imports of cell materials, small-scale manufacturing cells are mature; However, even if the battery solved the problem of materials, high-capacity high-power hp 396008-001 , pavilion dv9000 battery pack design and manufacturing is still faced with many problems, which is used in electric vehicle power battery technology breakthroughs in key technologies required difficult.
Chinese battery company in transition from development, lithium-ion battery industry, the market competitiveness of a large extent dependent on the accumulation of long-term development of the technology, rather than pure capital investment, and similarly, lithium battery cell materials have a high technical barriers, the small sub-industry leaders for the early entry into most sectors. However, the small lithium-ion hp hstnn-db20 , hp 395789-001 business, technical threshold is low, the influx of a large number of small and medium-sized participants in the industry cause profit margins to decline rapidly.

Storage battery types and maintenance

At present, our commonly used vehicle batteries are mainly classified into three categories, namely, ordinary batteries, dry batteries and maintenance-free battery charge three. Ordinary battery; ordinary dell d5318,dell 75uyf plates are from the lead and lead oxide composition, the electrolyte is sulfuric acid aqueous solution. Its main advantages are voltage stability, and inexpensive; disadvantage are the low specific energy (ie, per kilogram of dell u4873 ,dell gd761 energy storage), life is very short and frequent routine maintenance. Dutch Do battery: it's full name are dry charged lead-acid dell kd476 , dell td347 , which are the main characteristics of negative electrode plate has a higher storage capacity, in the completely dry state, can in two years by the electricity to preserve, use, Just add the electrolyte, such as over 20 - 30 minutes use. Maintenance-free battery: maintenance-free batteries because of their structural advantages, the consumption of electrolyte is very small, basically at the life Do not need to add distilled water. It also has earthquake-resistant, high temperature, small size, small self-discharge characteristics. Battery life is generally twice as common. Maintenance-free batteries on the market also has two kinds: the first at the time of purchase add disposable after use Do not need electrolyte maintenance (add supplementary liquid); the other is the inspiron 6400 battery itself, the factory has been well add electrolyte and sealed, Can not add users to simply add liquid. Battery use and maintenance of the main right there is 7 o'clock the following: 1, check the inspiron 8600 battery in the bracket on the fixed bolt is tightened, the installation is not reliable due to traffic vibration damage caused by Shell. Also not to be on metal to prevent short-circuit on the battery. 2, often view the very first column and the wiring connections were reliable. In order to prevent post-oxidation can be applied protective agent such as Vaseline. 3 can not be used to directly brand (short-circuit test) method to check the dell 8n544 battery power so the battery will cause damage. 4, ordinary lead-acid batteries should pay attention to regularly add distilled water. Dutch Do battery prior to use at best the appropriate charge. As to add water to maintenance-free inspiron 8500 battery is not able to uphold appropriate view, if necessary, add distilled water will help extend the useful life. 5, the latitude d800 battery should be covered with open pores. Rechargeable batteries will be produced at a large number of bubbles if the vents were blocked so that gas can not escape when the pressure increases to a certain extent it will cause a battery shell cracks. 6, columns and at the dell yd626 , dell 312-0393 cover, very often there will be around the yellow-white paste, this is because the sulfuric acid corrosion Genzhu, line cards, such as caused by fixation. Great resistance of these substances, it is necessary to timely and clear. 7, when the need to use two batteries in series using the same latitude d820 battery,latitude d620 battery capacity of the best. Otherwise, will affect battery life.

Battery basic design and fundamental steps

Designed battery power are engaged in chemical development and scientific research workers and technical personnel necessary knowledge and skills. Battery design is in accordance with the requirements of equipment to provide the best performance of the power supply or power supply. Therefore, the battery design must first be used to satisfy the electrical requirements and is optimized so that it will have the best overall performance, in order to determine the battery's electrodes, electrolyte, membrane, shell and other parts of the parameters, and reasonable with them, made of a certain specification and targets a cell or dell laptop battery. 2, the battery design requirements Batteries are Designed to meet the target (user or equipment) carried out at the request. Therefore, when the battery design before, we must first know the object of detailed performance indicators and the use of dell 2834t , dell 4834t requirements generally include the following: Battery voltage; Battery current job, that is, the normal discharge current and the peak current; Battery working hours, including the continuous discharge time, use the period or cycle of life; Battery work environment, including the battery in which job status and environmental temperature; The maximum allowable size of the inspiron 2000 battery , latitude ls battery . At the same time should also be considered: the source material; battery performance; battery characteristics of the determinants of battery technology; economic indicators; environmental factors. Evaluation of battery performance of key indicators Battery performance in general, primarily through the following aspects to evaluate. (1) refers to the capacity of latitude x300 battery , dell w0465 capacity at a certain discharge conditions, can be obtained from the battery power, that is current on the time points, the general has Ah or mAh to express it directly affects the maximum battery current job and working hours. (2) The discharge characteristics and the internal resistance of the battery discharge characteristics are approved batteries discharge at a certain system, its working voltage stability, voltage level of the platform as well as the large current discharge performance, it said the dell 1g222 , dell bat3151l8 with the load capacity. Battery internal resistance including ohmic internal resistance and electrochemical polarization resistance, large current discharge, the resistance of the discharge characteristics of particularly apparent. (3) Operating temperature range there is the working environment and electrical conditions require the use of battery at a specific temperature range with good performance. (4) storage performance battery storage for some time, due to certain factors so that performance changes, cause the battery self-discharge; electrolyte leakage; battery short circuits. (5) cycle life (secondary batteries) are referring to the cycle life rechargeable inspiron 2600 battery, inspiron 2650 battery system must be in accordance with the charging and discharging its functions reduced to a certain extent (for example, the capacity of the initial value of 60%) when the cycle number. (6) internal pressure and resistance to charge-off performance (secondary batteries) for Ni-Cd, MH-Ni-based rechargeable batteries such as sealed, high current battery charging process can achieve the balance between internal pressure to balance the stress of high and low, the battery resistance high-current charge-off performance measure battery performance are important indicators of good or bad, if the battery internal pressure can not balance or equilibrium pressure is too high, it will cause the battery pressure limiting device (such as explosion-proof ball) to open the inspiron 2200 battery , dell 312-0292 battery caused by discouraging or omitted fluid, and thus quickly cause battery failure. If the pressure limiting device failure, there may cause battery cracking or explosive shell. Battery design the basic steps Battery design Designed in a clear mission and fully prepared, you can design. User requirements in accordance with the inspiron 1000 battery , the battery design ideas, there are two: one is for the use of electricity and equipment to provide rated power capacity; another is given the form factor power supply, research and development of performance specifications of the new batteries or special battery. 1 to determine the capacity of the battery design steps Determine the combination of the battery cell body Alto number of job monomer dell 367759-001 voltage and operating current density. In accordance with user requirements of the job to determine the total battery pack voltage, operating current, such as indicators, the selected cell line, in the light of the series "V curve" (empirical data or through the experiment proceeds) to determine the work of monomer inspiron 6000 voltage and operating current density. Determine the battery pack in the number of single cell. The number of monomer battery voltage = battery job total monomer electric / battery voltage Calculation of battery capacity In accordance with the requirements of current job and working time rated capacity. Rated capacity = current * time job Determine the design capacity of Design capacity = nominal capacity * Designed coefficient Coefficient is one of the design in order to ensure the reliability and service life of the inspiron e1505 set, and general admission 1.1-1.2

Brife introduction Camera battery

Most camera batteries are lithium-ion batteries and nickel-hydrogen batteries Nickel-metal hydride samsung sb-l110 with a dedicated high capacity, low resistance, long life characteristics, and self-discharge is very small, high-current charge-point performance put a good resistance, charge-off. If you have a digital camera, please note: Use the process to avoid over-discharge situation. Have a discharge that is more than the limits of power consumption. Otherwise, even if the recharge capacity can not be completely restored, the battery is a kind of injury. Because of over-discharge efficiency will lead to deterioration of battery capacity to reduce this video cameras are equipped with samsung sb-l160 alarm function. So in the event of such a situation should be the timely replacement of batteries, as far as possible not to let the battery run out of a video camera automatically shuts down. If you intend not to use a digital camera a long time, we must want from your digital camera samsung sb-l220 charger with or removed, and fully discharged, and then stored in dry, cool environment, but try to avoid the battery with the general metal items stored together. In order to avoid short-circuit the battery problem, the battery when not in use should be covered to protect its preservation. The charging time depends on the charger and battery used, and the use of factors such as voltage stability. Usually give first use of the samsung sb-l320 , samsung sb-l480 (or used for months without batteries) rechargeable, lithium batteries must want more than six hours, Ni-MH battery must want it more than 14 hours, otherwise the future will be a shorter battery life. But also have residual battery power when not to repeat the charge as far as possible to ensure that the battery life.

Digital camera battery types

Digital camera battery required to maintain normal operation. Under normal circumstances, a digital camera can be used dry batteries, alkaline manganese batteries, nickel cadmium batteries, nickel hydrogen batteries, lithium-ion batteries and lithium batteries as its power supply. Alkaline manganese dioxide batteries Such batteries are in the market on our easy to buy on the 5th Sony np-fc10, they have not been special materials and technological transformation, the use of such batteries for digital cameras at the bottom of many products. Since marketing a wide range, so the user need not worry about the price of this battery, but also because of technical general, the capacity and endurance are far inferior to other than a few batteries. Sometimes, it's not enough to bring a digital camera electric start, and even digital cameras will have an impact. Ni-MH battery Such batteries are nickel-cadmium Sony np-fc11 early alternative products, as opposed to nickel-cadmium batteries, nickel-hydrogen batteries have a more noticeable advantage. It greatly reduces the nickel-cadmium batteries existence of "memory effect", which makes the use of nickel-hydrogen batteries more convenient and more long cycle life (up to 1000). In addition, Ni-MH battery also has a high electric capacity, depth of discharge, and resistant to overcharge and over discharge, charging time is short and so obvious advantages. Above all nickel-hydrogen batteries are no longer the use of toxic heavy metals as a material, can eliminate its impact on the environment. At the same time, the electrical properties of nickel-cadmium batteries with a basic similarity, in practical applications can replace Ni-Cd battery without the need for any transformation of the camera. Of course, the nickel-hydrogen Sony np-fe1 are not perfect, it has some disadvantage. Its relatively poor high temperature properties, at high temperature above 45 degrees Celsius environment, as well as 0 degrees Celsius below the low-temperature environment, the nickel-metal hydride battery will not work, or even simply can not start the camera. In addition, the battery self-discharge rate is relatively high, storage after a period of time will find it significantly reduced power, there is a nickel-hydrogen batteries are also exists a slight memory effect. Lithium batteries Lithium-ion Sony np-fr1 price is relatively high, but it has a light weight, large capacity, energy density advantages, compared with the nickel-hydrogen batteries, lithium-ion batteries are relatively portable, while the energy is higher than 60%. Precisely because of this, lithium-ion battery production and marketing is becoming more than nickel-metal hydride batteries, digital camera, now become the main one used in the battery. In addition, the lithium-ion battery is almost no "memory effect" as well as non-toxic substances, etc. It is also an important reason for wider application. Lithium-ion batteries and lithium Sony np-ft1 technology status, performance better than the only slightly higher prices, to use and more meticulous and complex, especially lithium-ion battery charger must be "exclusive", it should not charge the battery with other browser compatibility. Alkaline manganese dioxide batteries, although the low unit price, consumers could afford to buy, but its short life, long-term use so that ordinary consumers can not bear the cost. In contrast, nickel-cadmium batteries, nickel metal hydride batteries are currently in the manufacture of more technologically sophisticated, the price more reasonable battery. If you are using does not match or pay no attention to save the Sony np-fs11, the battery will be shooting at you did not run out a few photos. The following approach can save the battery usage: first, try to avoid using unnecessary zoom operation; second, to avoid frequent use of flash, flash power consumption are big, as far as possible avoid the use of U.S.; Third, adjust the screen at the best use of the viewfinder when the composition browser, and not to use the LCD. Since most digital cameras are due to open the LCD viewfinder and consume more electricity, it can turn off the battery backup time for growth in two or three times; Fourth, to minimize the use of Continuous function. Continuous functions of a digital camera most of the airframe using the built-in cache to temporarily preserve a digital photograph. If regular use of these caches, then the power required for very many. Therefore, to reduce the use of Continuous and dynamic video clips shot function, there is a lot of power assist.

Environmental protection department in Guangzhou City to commemorate the World Environment Day organized by the "green exercise, healthy life" activity, that the battery consumption of a big market - Guangzhou is facing a very serious battery pollution. The environmental protection departments of the Guangzhou City sources, Guangzhou City battery pollution almost to the "shocking" level, country specific legislation hope to tax forms to allow manufacturers and distributors to assume obligations deal with used batteries. Relevant data show that China is a superpower in battery production, sony laptop batteryconsumption is a big country in 1999 produced 15 billion batteries, consumer 7000000000. Guangzhou City in 1999 one of the production of battery 1,500,000,000, total output 30,000 tons, up 1.8 billion this year. Annual consumption of about 500 million, accounting for the total battery consumption of 7.41%.
According to information provided by sanitation department, said in Canton a year from picking up trash around 2000 tons of sony pcga-bp1n , sony pcga-bp2nx every year, about 400 million batteries 8000 tons of used batteries through various channels have been abandoned out. Because of the lack of appropriate supervision and regulations, disposal measures lagged behind, resulting in Guangzhou is facing a battery of pollution brought about by a serious threat. In this regard, developed countries such as USA, Japan on different categories of waste battery management have corresponding laws and regulations, some countries have also established a relatively sound and recycling of waste electric system. Guangzhou City Environmental Protection Department for this purpose called for introduction of relevant measures, so that cadmium, mercury battery production and sales to vendors to the environmental protection department to declare the sale variety, quantity, and to assume the form of tax revenue after the deal with battery disposal obligations.sony pcga-bp2r , sony pcga-bp2s ,sony vgp-bps5 , sony vgp-bps8 , sony vgp-bps9 , sony vgp-bps10.

The EU will enhance environmental protection standard for battery

Joint enterprise sectors Recycling batteries

Every year, people who have near 20,000 tons of scrap battery scooters in urgent need of proper disposal. However, this renewable resource was riveting on the illegal traders. 17 tons of annual processing capacity of the informal channels, people have to worry about it: it leaves the tens of thousands of tons of waste batteries become whether "environmental bomb"? Yesterday afternoon, led by the bicycle industry associations and introduced a series of initiatives to start the original almost completely out of control of electric vehicle batteries renewable deal with questions,apple laptop battery,into a relatively closed "security ring." Status: 20000:17 informal enterprises are helpless Mr. Wu is for the public to the car recently for "rations" and worry about the problem. "Early last year, when buying a car, dealers say they can get the old paste replacement battery, but the lap asking prices down, it seems obvious for at dealers here than at some near point is more cost-effective repair." Redemption of a group of same apple a1175 , apple a1185 ,, dealers expensive than the stalls on thirty to forty of dollars, it a bit hesitant to allow Mr. Wu. "In fact generated by the current annual 20,000 tons of electric bicycle batteries, almost all can be recycled, but at how recycling, the question on how to use it problematic." Bicycle-related industry associations said. The Shanghai environmental protection department audit only identified and licensing professional leaded waste treatment plant --- ShangHai flywheel is director of the non-ferrous smelter Gu announced a startling data: from 2000 to 2006, the plant the actual from the electric bicycle manufacturing enterprises to the Recycling electric vehicle apple m9324 , apple m8403 only 102.7 tons. Down conversion, only 6 years 8000 trips electric car batteries have been completely legitimate deal informal.

Carry out waste treatment Recycling batteries

With the growing number of electronic products, batteries can be seen everywhere in the figure, almost every one, everyone has to use batteries. It is learned that in our country the battery consumption of about 600 tons! With the development of electric, battery usage is still increasing. Although the battery to bring a lot of convenience, but after the batteries but environmental pollution is very serious and the U.S. led to serious concern. According to reports, one on the 1st acer laptop battery buried in the land, which enables one-square-meter permanent loss of use of the value of the soil! If a button battery into the water, it will 600 tons of water pollution, this is a person's life the sum of drinking water! Recycling used batteries but now has become a problem.
We want to collect it from the pollution of our environment, but no place can be recovered to pay! Seeing so many land and water has been contaminated, the health of people constantly being threatened, therefore appeal to all levels of government are immediately addressed the acer lcbtp03003 ,acer aspire 1300 when the problem of pollution! Otherwise, not a piece of pure land of future generations. Is therefore recommended that: 1, the National People's Congress should quickly enact legislation and to develop specific measures to ensure the implementation of this law. Who production requirements such as who Recycling treatment, taxation tilted,acer btp-43d1 , travelmate 220 battery , economic reward and punishment, media monitoring and so on; 2, at all levels of government should be vigorously publicized through various channels do not waste battery recycling serious consequences, including women and children to achieve well-known (now the publicity is far from enough), and the corresponding set up Recycling Network. In rural areas of each village, each town has a community recycling points, village and neighborhood committees to regularly collect used acer btp-58a1 , ace btp-60a1 according to the network level recovery; 3, the battery should also have point-of-sale collection of scrap batteries Recycling duty; 4, in order to enhance the enthusiasm of consumers Recycling, at the same time vigorously publicized return must be the appropriate amount of money, if a section on the 5th battery back-fifth of the money of the iceberg, or a few sections of scrap travelmate 240 series battery , ace btp-52ew in exchange for a new battery, or in exchange for an equivalent renewable products (such as renewable pencil and recycled paper ... the book ... and so on). Recycling efforts are to implement the acer batcl50l , travelmate 290 battery time to waste, we must pay close attention to step up again! Otherwise protect the environment is just empty talk. v
