Days can be dynamic (00819.HK) is the mainland's largest electric bicycle powered battery suppliers, with 22% domestic market share. At present, the days can be the main profits come from electric bicycle batteries, first half of 2009 compared to 93%. Taking into account the impact of the replacement market, we estimate that the Mainland's demand for battery-powered electric bicycles will remain at 15% -20% growth rate. Therefore, we believe that the current main business days to at least the next 3-5 years, the company's development can provide a stable source of income.

Mainland's large-scale promotion of new energy vehicles, lead-acid batteries in the middle and low-car market has a strong competitive edge. Compared to lithium batteries, lead-acid batteries with a clear cost advantage, the cost is only about 30% of lithium batteries; In addition, the lead-acid batteries are easy to recall and re-use nature. Therefore, the main three kinds of power batteries (lead-acid batteries, lithium batteries and nickel-metal hydride apple laptop battery) can share a huge market for new energy vehicles, but does not produce a complete substitutes for one another.

We are bullish days in low-speed electric vehicle motive power battery market competitiveness of days in low-speed electric vehicles, as well as middle and low expansion of new energy vehicle market, will most likely be another day to future performance growth. We expect that by 2010 the proportion of the new revenues will account for 10% of the company's total revenue of about, and this proportion will continue to rise over the next five years. It is learned that day to have reached an agreement with Chery, Chery become a pure electric vehicle apple a1008 battery (S11 models, with lead-acid battery-powered batteries) strategic cooperation factories. Chery 11-12 this year has reached 1000 monthly production is expected in 2010 that the model output in the 3-50000.

Low-speed electric vehicles generally refers to the speed of about 50 kilometers per hour, driving range of 100 kilometers vehicles. These models at the lower price, generally around 3-40000 yuan. Shandong, Jiangsu and Zhejiang and other places in recent years, some companies are seeking to develop low-speed electric vehicles. According to July 2009 opening of the National Conference of light electric vehicles, the current domestic production capacity reach 30 million units, sales of tens of thousands of vehicles, the apple a1039 battery  market mainly in Shandong province and abroad. "Shandong Province, the revitalization of industrial restructuring bicycle electric car guidance," points out that by 2011, the province's electric bicycles, light electric vehicles, mini-electric four-wheel vehicle production reached 3.6 million, respectively, 800,000 and 15 million units. But the low-speed electric cars are also policy risks.

 Most of the low-speed electric vehicle production enterprises do not have automobile production qualification, so can not be on the low-speed electric car motor vehicle license. Thus, despite the letter of the Ministry of National Development and Reform Commission and the Public does not expressly prohibit the development of low-speed electric car industry, low-speed electric vehicles are not in the Government's energy-saving and new apple a1012 battery energy vehicles set out the scope of encouragement.

Days in low-speed electric vehicles, as well as medium and low new energy automotive business expansion, the company will bring new growth momentum, based on the most careful consideration, we offer days to 2010 PE of 11 times; based on the forecast earnings per share ,2009-2011 were 0.27 yuan, 0.35 yuan and 0.42 yuan, we have raised the target price to 4.33 Hong Kong dollars, raised rating to "overweight." apple a1022 battery,apple a1057 battery,apple a1060 battery.

And accelerating the development of new energy sources, is this year's government work report of the important issues in the forthcoming World Expo will debut a new energy vehicles, the NPC has also become the focus of heated debate. Since last year, China's new energy auto show the trend of accelerated development, policy support is increasing, new energy vehicles has become the car of the future development of an important direction.  

Country Gold Securities (28.63, -0.06, -0.21%), Meng Tao Li, principal analyst for the automotive industry, said the new energy vehicles involved in the upstream industrial chain, metal, raw materials, such as the production of batteries needed to power the metal nickel, lithium carbonate dell laptop battery , as well as the middle cell plants, as well as the downstream vehicle class enterprise. In the whole industry chain, the production power battery part, due to its technical difficulty of the largest and therefore most likely to generate high profits.  

New energy vehicles powered inspiron 6000 battery including lithium batteries, nickel-metal hydride batteries, lead acid batteries and super capacitors are four. Currently over 95% of the use of nickel-metal hydride batteries, but lithium batteries are the future trends. Japan authoritative market research agencies - Japan's Fuji Co., Ltd. the latest economic forecast, the next 12 years, the fuel cell market will grow to more than 150 times last year, including fuel cell vehicles will play a major stimulating role. 

The new energy automotive XPS M140 involved in A-share listed companies have 10 or so, this year's market performance of these companies are very compelling, relevant companies, such as Shanshangufen (11.59,1.05,9.96%), the largest increase up 155%, CITIC Guoan (11.20,0.41,3.80%), and Section power far were 126% and 124%, Jiangsu Guotai from mid-October last year, began a unilateral rise in total rose 335 percent.  

Li Mengtao that determine the prospects for power batteries, it is necessary to analyze three aspects: First, battery performance, charge a battery can run the number of miles, you can use long life; second is the cost of the Latitude D830, the cost is too high there is no prospect ; Third, the battery safety. Currently, the new energy vehicles are mainly from a gasoline engine, power batteries, supplemented by the model, the gradual transition to the main power battery, gasoline engine supplemented by, in this transformation process, the power battery sharp rise in demand for lithium batteries advantages of various aspects will play out as the most important hybrid electric vehicle power source.

On the new energy vehicles to battery-related companies the opportunities brought by the companies themselves, of course have a voice. Representation of this reporter went to the two companies to understand the situation. Among them, Keli is far from nickel-metal hydride batteries the largest manufacturer of nickel foam material, the reporter arrived in the company when the company first nickel-hydrogen battery production line equipment have arrived in workshops, technical personnel are nervously installation. According to the company the person in charge of this production line will produce 3600 sets of nickel-hydrogen battery, the first product will be available by the end of March early April off the assembly line. Concern to the market lithium KD476 nickel dispute, Keli far that the nickel-metal hydride batteries in reliability, safety and low-cost areas still has a large advantage, and have been able to achieve scale, industrial production is expected in the future 8 to 10 years, nickel-hydrogen batteries will be the market share of 70% to 80% of the share. Even if the future lithium batteries to achieve a technological breakthrough, they can not completely replace the nickel-metal hydride batteries, but many are nickel-metal hydride and lithium batteries in parallel pattern. 

Shanshangufen involved in the lithium Inspiron 1501 industry, the middle and upper reaches. Lithium-ion batteries are the five main components: anode, cathode, electrolyte, copper foil and misunderstandings. Shanshangufen to do one of three kinds, positive and negative output of the domestic number one, the electrolyte came in third. Cathode production plant in Changsha, cathode production in Shanghai and Ningbo, the reporter went to a factory located in Guangzhou electrolyte. In 2008 the output of this yard is almost more than 1,000 tons, compared with 2007 increased by 50%. Products are now mainly used in a number of digital communication products, the company's plan is to further enlarge, the can be applied to electric vehicles, to open broad prospects for another one. 

Li Mengtao said the technical strength advances should not be underestimated the impact of the Industrial Revolution. Looking back out of cell phone lithium battery Ni-MH batteries, only two years, once the lithium Inspiron 1520 industry, technology has matured, it should be will soon be time to replace the nickel-metal hydride batteries, becoming the mainstream of new energy vehicles. 

In this regard, the Joint securities analysts Yao Hung-kwong also forecasts that within five years will completely replace lithium batteries nickel hydride batteries. Proposes a focus on CITIC Guoan, Jiangsu Guotai, Ke-li Yuan and China Baoan (8.38,0.33,4.10%). GF Securities Mrs Minnie LAI WEI-ching, that in the new energy automotive industry chain, the biggest investment opportunities in the battery, and now faced with two kinds of nickel-metal hydride and lithium battery technology road competition, short-term more than 95% of the nickel metal hydride battery-based, lithium Inspiron 1521,Inspiron 1720,Inspiron 1721,GK479,FK890,Inspiron XPS M170,Inspiron E1705,INSPIRON 2600,INSPIRON 2650 in the future will certainly be replaced, but the timing uncertainty. Proposes a focus on Keli far.

Last week, the application period is approaching, several U.S. battery manufacturers are trying to win government funding. Battery is the world's next big technology is one of the United States are trying to regain lost ground from the Asian competitors. 

The U.S. government designated this year, nearly 190 billion U.S. dollars for the support from the alternative fuel to energy-efficient building materials, including "green" technology. Battery manufacturers competing for funds is how the Government will boost funding for the first time the use of this test. 

In view of its electric and hybrid vehicles for the importance of the military applications, advanced ibm laptop battery is considered a strategic technology. 

Like 20 years ago, the chip industry, the United States in battery technology has lagged behind the Asian manufacturers, who have begun to invest in mass production.

Quallion and business development director Paul • Beach (Paul Beach), said: "the United States and Europe ignored this change." This ibm thinkpad r50 battery manufacturers hope to stimulate the financial help, to raise up to 2 billion dollars. 

He added: "Without government support, the battery industry is likely not start." 

• Greenberg, James (Jim Greenberger) added: "The United States manufacturing technology enterprises in the program has been lagging far behind. We have the status of the battery industry like the automotive industry, like the current situation, if we do not start developing their own battery industry, the situation is will be even worse. "Greenberg is a small ibm thinkpad r50e battery manufacturers in charge of the League, they are looking for 600 million U.S. dollars of funds to establish a joint factory. 

Use in advanced lithium-ion battery technology, many breakthroughs have originated from Japan, most of the manufacturing operations are concentrated in Japan, South Korea and China.

As the industry is difficult to obtain funds to leave the United States Government how to use the advanced ibm thinkpad r50p battery manufacturer's 2 billion U.S. dollars to stimulate the fund may decide the industry pattern.

Funding applications due tomorrow is expected as early as early July the government to decide how to use the money. A few months later, will decide how to use the ibm thinkpad r51 battery surplus to stimulate the funds - is expected that these funds would be in determining the other "green technology" industry, a similar pattern to play a key role.

China has independently developed a new and efficient environmental protection batteries (all vanadium flow storage batteries) has excellent reliability and stability of its engineering and industrial development has laid a solid foundation. The battery is no longer failure, continuous operation for two years, total running time of more than 17.5 thousand hours to achieve charge / discharge cycle over 4,500 times, and the energy conversion efficiency of the battery module to find any attenuation.

The battery is a researcher from the Chinese Academy of Sciences DICP Zhang China research team led by research and development. According to Zhang China introduced them in 2006, 2008, respectively, to develop China's first 10kW and 100kW vanadium redox flow battery energy storage system, has been the Group of Experts identified as "the leading domestic and international advanced." "All-vanadium redox flow asus a31-s5 battery，asus a31-s6 battery for energy storage technology of choice in the field of energy storage technology, one in comparison with the traditional lead-acid batteries, has many advantages: its output power and storage capacity can be independently designed to meet different application needs; its cycle life for the latter's 3-5 times the energy conversion efficiency of 50% higher than the latter; use will be fully discharge the battery without damage. In addition, all vanadium flow storage batteries safety and environmental protection, maintenance costs are very low has obvious technological competitiveness. "

According to reports, as a highly efficient energy storage devices, all-vanadium redox flow battery energy storage applications and asus a32-a8 battery，asus a32-m9 battery market prospects are very broad: can be used for wind, solar and other renewable energy power generation systems to solve its power generation is not continuous instability; available in the power system to regulate the client load balancing, to ensure stable operation of smart grid; can be used for electric vehicle charging stations, to avoid the high current charging electric vehicles on the grid impact. In addition, the flow energy storage battery can also be used in high energy-consuming enterprises, and should be telecommunication base stations, the state's important sectors such as backup power plants.

At present, the batteries have arrived in Lhasa, in Tibet, a "solar photovoltaic power generation - Energy Storage Battery storage power flow," the joint application and demonstration of power supply system. In October 2008, DICP and Bo Rong (Dalian) Industry Investment Co., Ltd. a joint venture set up a "melt in Dalian Branch Energy Storage Technology Development Co., Ltd.", specialized in engineering flow battery energy asus a32-s5 battery，asus a32-s6 battery storage and industrial development. They also provide a set of national grid 100kW/200kWh vanadium redox flow battery energy storage system for battery and application characteristics of the net inspection.

Ningxia International Hotel Hong Yue Prince 5 years collected more than 12,000 pieces of used batteries, not only did not place, becomes a "burden" and even accused of "bad for the environment." This is how the matter in the end?

Thousand pieces of used batteries can not find the "destination"

According to Xiang Yue Prince Ningxia International Hotel Human Resources official said, the hotel opening date, five-year period were collected inside the remote control out of more than 12,000 pieces of used ibm laptop battery, installed in three large cartons placed inside the Treasury, but had no relevant departments to deal with these used batteries.

During the interview, autonomous regions and staff of EPA Solid Waste Management Center, said there is no dedicated facility to focus region to deal with these cells, currently unable to recover, it is recommended to place the hotel on their own good. "Can not immerse themselves in water to prevent battery corrosion, non-flammable, and explosive materials together."

Acceptance phase of the project in Ningxia is the first hazardous waste disposal center, said could not close at euphemism, saying the center is currently in the disposal of used IBM thinkpad t40 battery  no related businesses.

Yinchuan Rongjie life treatment and disposal of solid waste Limited, said the company untreated similar things, but such a focus on the number of batteries require special handling, costs 1,000 yuan, even if the paid services, they also worry about contaminated solid waste disposal system .

Whether the environmental protection department or related businesses are referred to one thing: the current market, 5, 7, the thinkpad t41 battery has reached the low-mercury, mercury-free standards, can be natural degradation, the state does not encourage the pooling of recycling.

This seems to be the people's enthusiasm for environmental protection is slightly different.

7 years ago, has not recovered Batteries

5, 7, batteries do not recall it?

The answer is yes.

EPA regional staff of Solid Waste Management Center, said: "Over the last two years, production of 5, 7, thinkpad t42 battery  are environmentally friendly battery, can be directly sent to the refuse transfer stations, centralized recovery but good enough."

Some people wonder, "is not there is information indicating that a cell to rot on the ground can make 1 square meter of soil permanent loss of use value, a button battery is equivalent to a person's life can not be drinking water intake, how would not have recovered of? "

October 9, 2003, the State Environmental Protection Administration, the National Development and Reform Commission, Ministry of Science and Technology, Ministry of Commerce and other ministries, developed jointly issued the "Waste Battery Pollution Prevention and Control Technology Policy", the policy clearly stipulates: "Do not encourage the pooling of the collection has reached the national low mercury or mercury-free batteries required waste time. "commonly used in 5, 7, the  thinkpad t43 battery has reached the low-mercury, mercury-free production standards, decentralized disposal will not pose a pollution of the environment, but together handle more trouble processing technology immature.

"Section 5, the battery will pollute the 60 liters of water." This error message as early as seven years ago changed!

The number of enthusiastic people have been "kept in the dark"

As early as 2003, the state 5, 7, the battery is not to promote recycling, however, the public know?

2 days, the reporters on this random street interviews. Xingqing District, Yinchuan City, who lives Lutheran communities, Aunt Ho said: "The State is not advocating centralized collection of the battery? I put the  thinkpad r50 battery not only at home a special box to my son's home, his daughter home, the battery also collected in the street see also picked to go home, can I also disservice it? "

In the 17 people interviewed, no one knows 5, 7, batteries do not focus on recovery. On the contrary, the past, environmental education and cultivation of the public to consciously focus on the good habit of used batteries. Environmental protection departments have also said they often receive people who want to "hand over" the battery advisory telephone, although it will do correlation, but the people who know the policy changes are few. Throw used batteries in the end of the how?

Home run out of used batteries can not throw? The how throwing?

"Waste Battery Pollution Prevention and Control technology policy" which says that the public commonly used 5, 7, once the thinkpad r51 battery  no longer have to waste recycling, but the cell phone batteries and button batteries are still heavy pollution, we must focus on recovery from the manufacturers, the public can not readily throw away.

EPA regional staff of Solid Waste Management Center, the state does not encourage the collection of mercury-free low-mercury "waste time" battery, 5, 7, refuse to follow along with the battery directly thrown into the trash can, but one thing to note, driven by the interests of individual businesses, battery production standards and unqualified people to make choices in buying the battery marked "mercury-free environment," the word battery. For the mobile phone batteries and button-type batteries, stands to reason, follow the "From Where to buy Where to get" principle, by traders and taken to focus on recycling manufacturers. In fact, as "unprofitable", clocked the few merchants are willing to live. In addition, the state-to-business recycling of used  IBM fru 08k8193 there is no law, waste battery recycling disposal laws and regulations need further improvement.

The protagonist of the era of green battery contest triggered a lithium-ion batteries and nickel-metal hydride batteries duel between Li-Quan Chen even the Chinese Academy of Engineering, said: "Lithium-electric cars in China in the fierce international competition in a rare historical opportunity, lithium electric cars will bring a field energy revolution and industrial revolution. " 

Japan quietly shifting to the

Recently, Japanese research and development direction of new energy vehicles have been quietly changing. 

Major automotive and battery businesses have invested in building lithium-ion power battery production line, concentrated in the 2010 ~ 2011. Even the nickel-metal hydride batteries "endorsement model," the Toyota Prius is also considering the use of lithium batteries. Japan's Fuji economic analysis, the mainstream nickel-metal hydride batteries will be able to continue until 2011, but after 2011, Li-ion battery will gradually erode the market share of the nickel-metal hydride batteries.

By Nissan Motor (Nissan), Nippon Electric and East King founded a joint venture AESC company, has begun high-performance rechargeable lithium battery of electronic trial production. Expected to lead for the 2010 launch of Nissan electric cars and hybrid vehicles. AESC manufactured lithium acer laptop battery, claims to have the more traditional nickel-metal hydride batteries nearly two times the power density, and the thin battery modules, thin shape also allows room for more spacious vehicle ride.

According to Japan Automobile Research Institute is expected, according to the popularity of hybrids is now estimated that by 2020, hybrid car in Japan will reach about 360 million. If the high-performance lithium acer btp-43d1 , travelmate 220 battery  for more promotion, usage is likely to further reach 7.2 million level. One newspaper here said that if Japan's next-generation automotive lithium batteries in the international standardization of certification to obtain opportunities to master the initiative, and the enterprises will benefit immensely. 

In this regard, the investment advisers new energy automotive industry researcher Li Sheng-mao, not without concern that the person who, without their finest hour, the current domestic enterprises will be some of the  acer btp-58a1 , ace btp-60a1 in 2010 and 2011, respectively, of its nickel-metal hydride battery production line expansion, its future may face the risk of investment recovery.

Staged protagonist struggles 

However, China has other plans. Public letter issued by the Ministry of the "new energy vehicles production enterprises and product access management rules" (the "" rules ""), caused an uproar in the market.

This "rule" was formally implemented July 1, will be a clear delineation of new energy vehicles for the initial stage, development stage and maturity stages of three different technologies. Fuel cell vehicles, hydrogen engine car and two cars were included in the initial stage ether; lithium-ion  travelmate 240 series battery , ace btp-52ew  powered hybrid passenger cars, commercial vehicles, as well as pure electric vehicles, is a developmental period; the use of lead-acid batteries and nickel-metal hydride battery hybrid passenger car, compared with maturity.

It is noteworthy that, in being the industry generally favored lithium battery electric cars, which fell after the nickel-metal hydride cell hybrid, designated in the development period. This also means that Buffett was optimistic about the market is also favorable for the lithium battery electric vehicles lost in the nickel-metal hydride ace btp-63d1 ,acer batcl50l hybrid hands.

Nevertheless, the Tsinghua University Research Institute of Automotive Engineering, said Song Jian, executive vice president, while 99% of the world battery market share of hybrid nickel-metal hydride batteries, but the high price of nickel, nickel-metal hydride batteries, the production costs higher than the lithium batteries out a lot. Compared with the nickel-metal hydride batteries, a new generation of lithium batteries will reduce the weight of half a charge storage capacity increased by more than double, a charge mileage will be greatly enhanced. And the Ni-MH  travelmate 290 battery , travelmate 4000 battery life in the next 3 to 5 years, will reach the limit. In the long run, lithium batteries will become the future development of new energy vehicles, more worthy of reliance on the power source.

According to the Investment Adviser published "2009 ~ 2012 China Battery Industry Investment Analysis and Forecast Report" shows that the new energy vehicles will be in the "Ni-MH - Lithium-Ion battery - fuel cell" industry-oriented development path. Lithium-ion battery in 2 to 3 years, although difficult to replace the nickel-hydrogen batteries, however, not be overlooked is the future of lithium batteries will replace the nickel-metal hydride batteries into the mainstream of new energy vehicles. 

Some experts suggested that China's car prices and the related battery business in addition to promoting the industrialization of nickel-metal hydride travelmate 2300 battery , aspire 1680 battery , more attention should be put some of the long-term, to devote human resources to carry out power lithium battery research and development, and maintain the fuel cell technology with the Jin, in order to occupy a broader new energy car market well preparation. 

To be the gold mining 

At the recent 5th Beijing International Electric Vehicle Exhibition of clean energy vehicles, "China Joint Business News" The reporters found that the bus manufacturer to bring exhibitors of pure electric passenger car with almost all the lithium battery. 

In fact, in the field of power battery, lithium-ion aspire 1410 battery ,travelmate 4500 battery involved in the project are not many. According to "China Joint Business News" reporter has learned, Changxing, Zhejiang enterprises with dozens of cells, but only 3,4 Families with lithium-ion battery project, the majority of enterprises in the production of lead-acid batteries. Beijing-based production and sales of lithium ion battery, company sales staff told the "China Joint Business News" reporter, along with electric cars and the rise of power batteries, power battery leasing, Electric Vehicle Charging Station and a series of new faces will also appear in front of us, This behind the need for a huge industrial chain to support. Experience tells us, "get head start" on the development of enterprises is very important.

It is evident from the face of the next situation, the Chinese battery companies should do a good job in advance, "Nuggets" preparation.

Japan IIT consulting firm reports that in recent years, electric tools used lithium-ion battery replacement nickel-cadmium acer lcbtp03003 ,acer aspire 1300 was accelerating trend, has become the addition to cell phones, notebook computers outside of the third-largest lithium-ion battery application object. No wonder some experts say lithium-ion battery market is a gold mine to be excavated: By 2020, China's auto motive power battery market will reach hundreds of billions.

Senior engineer of China Association of Automobile Manufacturers In an interview with the Li-chung "China Joint Business Daily," an interview, said: "Our lithium-based battery technology is better, although the scale and technical level in the industry with a little gap in Japan, but ahead of other countries. Automakers the establishment, often in order to seize the high ground, grasp the core technology standards as a precondition. In the current multinational auto giants have lithium  acer btp-aqj1 , acer btp-arj1 in the field of attack, and grabbing for market share, the Chinese Li-ion battery technology development efforts should be made. " 

Prior to the development of China's traditional automotive industry has been using to follow the strategy of the road. In the field of new energy vehicles, whether we can follow the route out, and gradually stepped into the leadership ranks, lithium asus a42-a3,ASM 92P1140 technology will be a key. 

1. Curing deep, deposited in the mine waste

Such as France and a factory to extract nickel and cadmium, nickel and then used in steelmaking, is re-used in the production of cadmium batteries. The remaining types of waste batteries are generally transported to a special toxic, hazardous waste landfill, but this practice is not only too expensive but also wasteful, since there is still a lot of useful material can be used for raw materials.

2. Recycling 

(1) heat treatment

Switzerland has two specialized processing and utilization of the old battery factory Batelieke companies to adopt the method is to grind the old battery and sent to the furnace heating, then can be extracted out of volatile mercury, zinc, when the temperature is also higher evaporation, which is also precious metals. After the fusion of iron and manganese into manganese alloy steel required. The plant can process 2,000 tons a year of waste XPS M140,Latitude D830, available 780 tons of manganese ferroalloys, 400 tons of zinc alloy and 3 tons of mercury. The other plant is extracted directly from the battery-iron, and manganese oxide, zinc oxide, copper oxide and a mixture of nickel oxide and other metal to sell as scrap metal directly. However, the heat treatment method more expensive, Switzerland, also provides buyers to each of the battery charge a small fee for exclusive processing of waste batteries.

(2) "wet processing" 

Magdeburg peri-urban areas are being built a "wet processing" devices, where the addition to lead-acid batteries, the various types of cells were dissolved in sulfuric acid, and then using ion resin extracted from the solution of various metals, raw materials obtained in this way than the pure heat treatment method, so a higher price in the market, and the KD476,Inspiron 1501 contains 95% of the various substances can be extracted. Wet processing can be avoided sorting areas (because the sorting is a manual operation, will increase the cost). Magdeburg annual processing capacity of this device up to 7500 tons, which means that while the cost is slightly higher than the landfill, but the precious raw materials will not be discarded, it will not pollute the environment.

(3) Vacuum heat treatment method

German Duarte's vacuum heat treatment developed in France but also cheaper, but that first need to sort out the waste batteries, nickel-cadmium Inspiron 1520,Inspiron 1521, used batteries by heating in a vacuum, in which the rapid evaporation of mercury can be recovered, and then the remaining ingredients ground, using magnets to extract metals iron, and then extract the powder from the remaining nickel and manganese. This process one ton of waste batteries costs less than 1500 marks.

Due to the high energy density lithium batteries, long cycle life, light weight, small size and other characteristics, but also has a safe, reliable and can quickly charge and discharge, etc., to become the new power technology in recent years, the research hotspot in the field of high-energy and high-power reserved popular. In the lithium battery structure, the inner membrane is a key component of the. Diaphragm made of plastic film is able to isolate the battery positive and negative, in order to prevent short circuit; also be in the battery overheating, through closed-cell function to block cell in the current conduction.

Depending on the physical and chemical characteristics, lithium-ion battery separator materials can be divided into: Weaving film, non-woven membrane (non-woven), microporous membrane, composite membrane, separator paper, rolling film several categories. Polyolefin materials have excellent mechanical properties, chemical stability and relatively inexpensive, and consequently polyethylene, polypropylene, microporous polyolefin membranes for lithium-ion dell laptop battery
 will be used as a research and development of early Lithium-ion battery separator. Today, the commercialization of lithium-ion battery separator is still polyolefin microporous membrane. In recent years, solid and gel electrolytes began to be used as a specific component, while playing the role of electrolyte and battery separator is a new technological means.

Li-ion battery separator battery costs account for the cost of a / 3. Membrane determines the performance of the battery interface structure, resistance and so on, a direct impact on the battery capacity, cycle performance, and security features such as, high-performance membrane in improving overall performance of the inspiron 6000 battery , inspiron 9300 battery , inspiron 9400 battery has an important role. At present 60% to 70% of the membrane market, mainly in wet bi-oriented process, because the wet, bi-lateral vertical stretch more evenly balanced. It is mainly used for high-end diaphragm wet, dry method has been applied in the low-end products.

Potential contamination of used batteries has caused widespread concern in the community. China is the world's number one dry battery producing and consuming nations, our data show that China currently has more than 1,400 battery manufacturers in 1980, the production of dry batteries volume has surpassed the United States and the largest in the world first. In 1998 the production of dry batteries in China amounted to 14 billion, while the same year the world's total production of dry batteries is about 30 billion.

Such a large quantity of batteries, making a big problem exposed, that is, how to make so many batteries do not undermine the pollution of our environment. According to our survey, used batteries containing heavy metals as well as the waste acid, waste alkali and other electrolyte solution. If you arbitrarily discarded dell laptop battery will destroy the corruption of the water, erosion of our survival crops and land, our environment is facing a huge threat. If the one on the 1st cell in the ground and rotting, it's toxic substances make one square meter of land to lose value; throw a coin battery into the water, which contains toxic substances which killed more than 60 million liters of water body pollution , equivalent to a person's life, water; used batteries containing heavy metals cadmium, lead, mercury, nickel, zinc, manganese, etc., in which cadmium, lead, mercury is a great harm to human body substances. The nickel, zinc and other metal although to a certain range of concentration is a useful material, but in the environment over the limit, but will also harm the human body. Waste batteries leaking heavy metals can cause rivers, lakes, sea and other bodies of water pollution, endangering the survival of aquatic and water use, an indirect threat to human health. Waste acid, waste alkali and so on could contaminate the electrolyte solution, so that land acidification and salinization, which decker around us like a time bomb. Therefore, the collection and disposal of used batteries is very important, if disposed of improperly, may be on the ecological environment and human health, cause serious harm. Randomly discard used batteries is not only pollute the environment, is also a waste of resources. Some people forget an account to the country's annual production of 10 billion batteries, annual consumption of 156,000 tons of zinc, 226,000 tons of manganese dioxide, 2080 tons of copper, 27,000 tons of zinc chloride, 79,000 tons ammonium chloride, 4.3 million tons of carbon rod. Despite the advanced technology has given us the right direction, but the phenomenon of pollution in China's battery is still not optimistic. Most of China's current domestic waste has been mixed with used batteries together into the ground, over time, after the battery into decay, heavy metal leaching, both could contaminate groundwater bodies, they could contaminate soil and finally through a variety of ways to enter the human food chain. Biological uptake of heavy metals from the environment through the food chain biomagnification, grade by grade in the higher organisms tens of thousands of times more enriched in, and then enter the human body through the food chain, and in some organs savings cause chronic poisoning, Japan Minamata disease is a typical case of mercury poisoning.
Batteries are generally divided into disposable batteries and rechargeable batteries. The main disposable batteries, including zinc-manganese batteries (zinc and manganese dioxide), zinc mercury batteries (zinc and mercury oxide) and lithium batteries and other several categories. The main rechargeable batteries include cadmium - nickel, iron - nickel, zinc - silver, zinc - air and lithium - iron sulfide and lead-acid batteries and so on. Our daily life is the most frequently used zinc-manganese batteries and zinc-mercury dell inspiron 1100 battery, leaving the battery pollution is mainly caused by mercury (Hg) and cadmium (Cd).

Mercury toxicity

Mercury, which are commonly called "mercury" is a liquid at room temperature the material, can prevent the dell inspiron 1150 battery in the cathode zinc oxide, this approach to improve the storage life of the battery. Thus, as early as in the previous zinc used in batteries to do extremely overcast almost all do a certain amount of mercury preservative. However, the chemical combination of mercury and mercury have the neurotoxicity of endocrine system, immune system, also have an adverse effect, it will trigger people's slurred speech, unsteady gait, limb paralysis, leading to generalized convulsions, mental disorders and died.

For a long time, China in the production of dry batteries, it is necessary to join a toxic substance - mercury or mercury compounds. China's mercury in alkaline batteries up to 1% ~ 5%, 0.025% neutral dry-cell batteries, dry dell inspiron 1520 battery every year for the production of dozens of tons of mercury amounted to much. As technology advances, the battery began to implement a low mercury and mercury-free, mercury substitutes Forafac fluorinated polymer surfactants in preventing the corrosion of zinc has achieved good results.

Discarded mercury dell inspiron 6000 battery in nature will slowly overflow from the battery into the soil or water, and then under the action of microorganisms, inorganic mercury can be transformed into methylmercury, gathered in the fish's body, the human consumption of such fish , the methylmercury enters the human brain cells, people's nervous systems were severely damaged, in serious cases would be crazy to death. Well-known Minamata disease in Japan is caused by methylmercury.

Cadmium Toxicity
Cadmium is not a trace element necessary for the human body, the body of newborn babies, and there is no cadmium, but increased with age, and gradually accumulated. Cadmium with renal toxicity, which caused kidney damage is irreversible. At the same time after renal injury may also be secondary osteoporosis, osteomalacia and fractures. In 1993, the International Union Against Cancer will be set at IA level carcinogen cadmium. For these reasons, many developed countries have recommended a ban on the use of nickel-cadmium batteries and nickel-metal hydride battery has been replaced by nickel-cadmium dell inspiron 630m battery, avoiding the use of cadmium. In China, the vast majority of battery manufacturers are still using cadmium as raw material for production of the battery, making the battery further increase the dangers. Affected by long-term consumption of cadmium contaminated water and food, can lead to bone pain and disease, cadmium into the body, causing osteomalacia skeletal deformities, and in severe form of natural fractures, and even die.

Manganese toxicity
Excessive levels of manganese accumulation in the body can cause neurological dysfunction, an early manifestation of an integrated sexual dysfunction, the emergence of heavier speech monotonous, dull expression, emotional indifference, accompanied by psychological symptoms.

Lead toxicity
Lead a major role in the nervous system, hematopoietic system, digestive system, dell inspiron 6400 battery,and liver, kidney and other organs, can inhibit the synthesis of hemoglobin metabolism, but also directly on the mature red blood cells, for infants, young children much, it will lead to children's physical development retardation, chronic lead in the prime of childhood mental retardation.

Nickel toxicity
Nickel powder dissolved in the blood, to participate in the body circulation, with strong toxicity, can damage the central nervous system, causing abnormal blood vessels, severe cases lead to cancer.

Zinc toxicity
Zinc is an essential element of the human body, less toxic, oral zinc sulfate 1000mg only people with acute poisoning, but the inhalation of zinc oxide dust can cause poisoning. Its symptoms are generalized fatigue, muscle pain, dell inspiron 640m battery,difficulty breathing, vomiting, diarrhea, severe heart weakness, prostration, convulsions died. Zinc sulfate, zinc chloride penetrated the skin mucous membrane, it can produce dermatitis and ulcers. Of zinc to fish and aquatic toxicity of the toxic than the people, so the water quality requirements for fishing in the water content of zinc per liter should not exceed 0.1mg.

Recycling of waste batteries
Waste dell inspiron 700m battery may be small, against Queshen big. However, due to pollution, waste batteries do not like waste, air and water pollution, as could any sensory feel it has great hidden, so did not receive due attention. At present, China's battery production and consumption to become a big country, and used batteries pollution is an urgent need to address a major environmental problem.

According to environmental experts, in the recovery of waste batteries per 1,000 grams of metal, of which there are 82 grams of mercury, 88 grams cadmium, can be said that disposal of waste batteries recycling is not only addressed the sources of pollution, but also achieve the recycling of resources. In developed countries the recycling of spent batteries and use very seriously. Many countries in Western Europe, not only in stores, but also directly on the street are equipped with a special battery recycling box, and used dell inspiron 8600 battery are 95% of the material can be recycled, particularly in high-value metal recovery. Such as the Foreign Secondary Lead industry developed rapidly, the current lead 55% of all production comes from regenerated lead. The Secondary Lead Industry in dealing with the regeneration of waste lead-acid batteries account for a substantial portion. 100 kg of waste lead-acid batteries can be recycled 50 to 60 kilograms of lead. Cadmium batteries for the regeneration of waste treatment technology abroad, have been more mature to deal with 100 kilograms of cadmium battery scrap recycling about 20 kg of metal cadmium, mercury dell inspiron 9300 battery are mainly used for the environmentally sound processing means to prevent the pollution of the environment . However, there are in this area of management rather weak.
