Shi introduced rechargeable batteries power three times as much zinc oxide lithium battery
Switzerland ReVolt company recently introduced a rechargeable zinc-oxide 312-0292 batteries, build capacity lithium battery 3 times, and cost only half of its lithium batteries. ReVolt The company plans next year, such small-scale batteries for hearing aids, and then extended to mobile phones and electric bicycles, the last may be applied to electric vehicles.
According to Yale University web site reports that this technology is based on Science and Technology Industrial Technology Research Institute Norway (SINTEF) design. Ordinary batteries containing reactant internal energy, while the zinc-oxygen cell using activated carbon adsorption of oxygen in the air as the cathode active material, zinc as the anode, to rely on ammonium chloride or caustic soda solution as the electrolyte. Compared with conventional batteries, zinc oxide battery is not easy explosion, build capacity is Inspiron 2200 greater.

ReVolt company said rechargeable battery to overcome the traditional zinc oxide zinc oxide battery a number of serious shortcomings, such as multiple charge the battery several times after power-on failures.

In addition, the company has also mastered the ReVolt in the electrolysis process to reduce the loss of electrode technology. Company CEO James? Mike Tao plus (JamesMcDougal) said that such a zinc-oxide cell battery can be recharged 100 times or more. He hoped for mobile phones and electric bicycles before the number of charge cycles can be achieved between 300 and Inspiron 1000 500 times.

Battery Electrolyte

Domestic battery manufacturers supporting electrolyte has been basically achieved domestically. Main raw materials for the electrolyte lithium hexafluorophosphate, accounting for about 50% of the cost of the electrolyte, its production cost is 10 yuan / ton, priced at 40 yuan / ton, gross margin as high as 75%, but the market was largely Kanto Electric the chemical industry, SUTERAKEMIFA, Morita chemistry, several Japanese companies a monopoly. Therefore, the urgent need to solve the most critical Inspiron 2000 lithium battery electrolyte lithium hexafluorophosphate electrolyte composition (LiPF6) large-scale production problems. Only the key technology to achieve breakthroughs in China's auto power lithium battery industry chain can be close to perfect.

Now the world's lithium battery electrolyte balance between market supply and demand, lithium battery electrolyte requirements of the relatively high, but the volume are few. For example a mobile phone battery with only 3 grams, the proportion of small, 2,000 tons of electrolyte can be produced 600 million mobile phone batteries. Vehicle power battery is not the case, and a car is necessary to 40 kg. Once the rise of electric cars will bring the explosive growth in the electrolyte.

China engaged in the production of lithium battery electrolyte enterprise mainly Juhua, Shanshangufen, Huarong Chemical Co., Zhuhai race Wei electronics, Tianjin, Taurus, Shantou golden, Guangzhou and a heaven-sent and so on more than 10. Among them, Huarong Chemical Co., Zhuhai race weft electronic positioning high-end market, other companies can only do low-end market.

Juhua (600.16 thousand): At present, very few companies able to produce lithium hexafluorophosphate, and in this one Juhua walking in the forefront of domestic enterprises, already have well-fluorine chemical industrial chain, advanced technology and rich fluorine chemical fluoride raw material. Lithium hexafluorophosphate production of raw materials anhydrous hydrogen fluoride, W0465 will be leading the development is of Jiangsu Guotai, Shanshangufen electrolyte lithium battery manufacturers and other upstream industry, the prospects are rather broad, it is worth focusing on.

4. Diaphragm:

Li Sheng-mao believe that with the gradual promotion of new energy vehicles, the future demand for power lithium battery materials will be detonated. Divide the Department of Li-ion materials technology, the highest barriers to a high-value-added material, gross profit margin is usually 70% or more, accounting for 20-30% of the cost of lithium batteries. Accordance with the terms of a car can be used in 1000-2000 m2 membrane. Divide the market is currently a serious shortage of supply, most dependent on imports, the market dominated by Japanese Asahi Chemical Industry, Tonen Chemical, and the United States Celgard dominate. Membrane with a typical "high-tech, high-capital" characteristics, and the project cycle is very long, the investment risk greater enthusiasm for investing in domestic enterprises is not high. At present, the domestic companies able to produce membrane only star-source technology, Jinhui High-Tech two technologies are relatively mature.

Fosugufen (000,973): In 2006, BYD Fosugufen co-financing with the 2.81 million U.S. dollars, set up Foshan Jin Hui Hi-Tech Optoelectronic Material Co., Ltd., which Fosugufen accounted for 55% of the shares. It is this company, it would Fosugufen and BYD conceptual link up. At present, the domestic annual demand is about 130 million square meters, while Jinhui company to 1,200 million square meters. Nevertheless, Jinhui company's annual 12 million square meters of membrane, which is used in the car on the little battery power, most of the battery is still used in communications. BYD, including sales to the membrane, it is mainly used in mobile phone use Latitude X300 lithium batteries. Financial data show that the establishment only three years, Jinhui company profits showed strong growth trend in 2008 has brought Fosugufen million profit in 2000.

Zhongda shares (600,074): Fosugufen up shares of peers in the membrane is king. Largest shareholder in Shin-tat-tat of shares in the Technology Innovation Group, a breakthrough in the search for new, independent research and development of new materials, production of solar photovoltaic, battery separation film and a number of leading international standard projects. Up shares in China's new materials, polymer soft plastic faucet, producing BOPP film, BOPET film, CPP film three series of products, production scale of China's leading, but these are mostly low-profile products, packaging materials used for to do, while the polyolefin film If used in lithium-ion separation membrane, thin-film solar cells will be worth a hundred times, the shares reached a Fosugufen like potential.

Power lithium battery and broad development prospects

According to the Investment Advisor "issued by China's new energy vehicles 2008-2010 Industry Analysis and Investment Consulting BAT3151L8 report" shows that the situation with China's energy resources and the development trend of the international automotive technology is expected by 2012, annual production will reach a new energy vehicles 1 million, while projected that by 2025, China accounted for regular gasoline vehicle holdings of passenger cars will be only around 50%, and advanced diesel and gas vehicles, bio-fuel vehicles such as the rapid development of new energy vehicles will be.

The future of new energy vehicles instead of the traditional automotive trend will become a necessity, power lithium batteries as a new energy vehicles in the "heart" will be spawned huge industrial and economic effects on the battery raw material suppliers and manufacturers who are huge commercial cake.

Is expected that by 2012 the annual production of new 1G222 energy vehicles will reach 1 million, according to each new energy automotive batteries costs 7 million power lithium battery cathode material lithium iron phosphate 52 kg, 41 kg anode material, electrolyte 40 kg calculations. 1 million hybrid vehicles will drive the 52,000 tons cathode material, anode material for 41,000 tons, 40,000 tons electrolyte needs. For domestic battery manufacturers, this would be a gross output value of 70 billion yuan of the big cake. If calculated according to passenger cars, this value will increase three times - each hybrid passenger car battery demand is four times that.

Power lithium battery will follow the rapid development of

By the international financial crisis, General Motors, Chrysler and other auto giant suffered heavy losses. To be born again, Laptop Battery car prices on the one hand cut through layoffs, selling assets, such as Brokeback to survive, while sparing no effort in the development of new energy vehicles in order to carry a downturn, China's new production cars by 2012 there were 10% of energy-saving and new energy vehicles The goal is clear-cut. New energy electric car the most important components is the driving force batteries, electric motors and energy conversion control systems, while the power battery to achieve fast charging, security and other high-performance, high technical threshold, but also the most concentrated part of the profits.

The new energy vehicles demanding on the battery, you must have a high specific energy, high specific power, fast charging and deep discharge performance, and requires the cost as low as possible, the use of Shou as long as possible. The traditional lead-acid batteries, nickel-cadmium batteries and nickel-metal hydride battery technology itself is relatively mature, but they are used in automotive batteries as a power, then there exists a larger problem. At present, more and more car manufacturers to choose from Presario 2100(compaq 2100) lithium batteries as a new energy car battery power.

Li-ion battery has the following advantages: small size, light weight, high voltage (which is nickel-cadmium batteries, nickel-hydrogen batteries 3 times) than the energy of large (up to 165WH / kg, nickel-hydrogen batteries 3 times), loop-shou long, self-discharge rate is low, no memory effect, no pollution, safety and good.

Development of power lithium battery

The future of new energy vehicles gradually replace traditional gasoline car has become a consensus of countries to develop the automotive industry, as a core component of the motive power by businesses and investors are more optimistic. Power battery is the key to the development of new energy vehicles: hybrid electric vehicle is the best transitional product, but a pure battery-powered cars is the future direction of development, core technology, a breakthrough in battery technology. At present many well-known car manufacturers are working to develop 319411-001 battery-powered electric vehicles, such as Ford, Chrysler, Toyota, Mitsubishi, Nissan, Hyundai, France, Courreges, Ventury so. While the domestic car manufacturer BYD, Geely, Chery, Lifan, ZTE and other car firms also have their own hybrid and pure electric vehicle powered by lithium battery power.

China's new energy automotive battery industry, Europe and the United States began late in the day, but the development is very fast, in the lithium battery research and development has also invested a great deal of financial and material resources. 863 plans to set up an electric vehicle major projects, Institute of Physics, Chinese Academy of Sciences, Beijing Nonferrous Metal Research Institute, China Electronics Technology Group Corporation 18th Research Institute, and other units participating in the project were the development of EV and HEV with two types of motive power batteries, Some units have adopted a security system of cathode active materials of manganese. "Eleventh Five-Year",F4812A 863 electric vehicles on the major projects also HEV, PHEV (plug-in hybrid vehicles), FCV (fuel cell vehicle) with power lithium-ion battery and battery research and development of key materials for support.

Bottleneck in the development of lithium battery power

Currently impeding the development of lithium-ion battery power bottlenecks are: safety performance and vehicle power battery management system.

Safety performance, because the lithium-ion battery with energy density and working temperature is high, poor working conditions and other reasons, coupled with the safety of people-oriented concept, so the battery safety of users made a very high demand. Auto power battery management system, since the vehicle power battery voltage is 12V or 24V, but a single power lithium-ion battery voltage is 3.7V, the battery must be by a number of series and increase the voltage, but because of the battery is difficult to achieve completely homogeneous charge and discharge, leading to a number of battery packs in series within a single battery charge and discharge occur imbalance, the battery charge will appear under and over-discharge phenomenon, and this situation will lead to a sharp deterioration in F4809A battery performance and ultimately resulted in the entire group of cells does not work, or even scrapped, thus significantly affect battery life and reliability.

China auto industry analyst with investment advisers that Sheng-mao, power lithium-ion battery to get a good application, which is technically required from the material, batteries, management systems, taking into account the mechanical processing and other aspects. Therefore, the need for upstream and downstream enterprises to work together with the battery as the core of the material, the management system requests formation of an industry group, more conducive to technological advances and system costs.

Power lithium battery industry and company analysis

Lithium battery materials can be divided into electrode (positive / negative) materials, separator and electrolyte. Li-ion battery cathode material is the core of the current lithium cobalt oxide, lithium manganese, lithium and nickel-cobalt-manganese-based lithium iron phosphate. Ze Yi graphite anode material, F4098A solid carbon particle-based; in the middle of positive and negative electrodes while the battery electrolyte and separator.

1. Cathode Materials:

Prior to this, the reason why the cost of lithium batteries is higher than nickel-metal hydride batteries, the main reason lies in its use of cathode materials based on precious metals as raw materials cobalt lithium cobalt oxide, lithium manganese oxide and lithium iron phosphate is more obvious because of cost advantages; however, and lithium manganese compared to the capacity of lithium iron phosphate higher density, the former 100-115mAH / g, the latter 130-140mAH / g; charge and discharge are living longer, the former is 500 times more than the latter up to 1500 times above; operating temperature range greater, the former from 0 to 50 ℃, which was -40 to 70 ℃. Thus, in lithium-ion batteries, lithium iron phosphate batteries the most promising.

In the lithium battery industry chain, the current capacity comparison, due to high barriers to entry,
Hp laptop battery lithium battery cathode material is the smallest capacity, which is the whole industry chain, the most promising aspect. Cathode materials currently in production companies are: China Baoan, CITIC Anhe Shanshangufen, BYD.

Shanshangufen (600,884): The company controlled by Shanghai Shanshan Science and Technology, lithium-ion battery cathode material sales revenue has become the largest the world's top three of the cathode material suppliers. However, its gross margin in 2008 was lower than the industry should have a minimum level, gross margin was only 14.21%. It is understood that Shanshangufen lithium cathode material, its production capacity both lithium and cobalt-manganese, lithium is not the industry's most promising lithium iron phosphate, but technically do the tracking. Cathode materials, high-profit, Shanshan was "only income not do profits", the negative electrode materials have technical advantages, but a lower gross margin less than the level of support for 4834T the overall performance of Li-ion battery production.

CITIC Guoan (000,839): As the owner of a small lithium battery industry two key links in the chain - upstream and downstream of the lithium carbonate lithium-ion battery company. Qinghai CITIC Guoan currently holds 99.375% stake in national security, mainly engaged in Qinghai Salt Lake, West taijnar lithium, potassium, boron, magnesium and other resources of the comprehensive development. West taijnar Salt Lake Qaidam Basin is located in the middle, according to design capacity calculations, the above resources available to the company for at least 25 years of mining, the potential economic value of 170 billion yuan. Addition to the upper reaches of lithium resources, holding 90% of CITIC Guoan, a subsidiary of CITIC Guoan Mengguli company, is currently the largest lithium-ion secondary battery cathode material of lithium cobalt oxide and lithium manganese oxide production enterprises, accounting for lithium cobalt oxide Products for 40% of the domestic market share.

China Baoan (000009): The company has equity participation 2834T Tianjiao Technologies is a set of lithium batteries are grade material research and development, production and sales of high-tech enterprise, the company's leading product is the current nickel-cobalt-manganese lithium battery cathode material (cathode triple materials).

2. Cathode Materials:

Compared with the cathode material, anode material for lithium battery costs accounted for the proportion of low-and domestic-oriented industries has been realized, the negative electrode materials, graphite, solid carbon particle-based. Currently engaged in lithium battery cathode material production enterprise in China, the top three national security, Shanshangufen, Long Sand Sea capacity, at present anode material able to basically meet the needs of the domestic market, but with the increasing popularity of new energy vehicles, the future market for this one a huge gap in demand will occur.

China Baoan (000009): Shenzhen Baoan Bei Terui is 55% owned subsidiary, is the carbon anode materials for lithium battery standard-setter. Latitude LS Of its production capacity of carbon anode material is 6,000 tons / year, the price of 6 yuan / ton, up to 80% market share, ranking second worldwide. Clients include Panasonic, Hitachi, Samsung, TCL, BYD, etc. more than 130 manufacturers. In 2008, Bei Terui the acquisition of Tianjin Railway Prudential to carbon anode materials for cost reduction by 30%. Although a subsidiary of battery materials business is booming, but the overall size of the market by the restrictions on listed companies in China Baoan, the contribution from the performance of battery materials is difficult to rely on. China Baoan main business is real estate, medicine, first half of 2008 accounted for more than 90% of income, including lithium, including other income accounted for less than 9%.

Shanshangufen (600,884): Bei Terui Shanshangufen is a great competitor. Owned subsidiary of the company, Shanghai Shanshan Science and Technology, 1,200 tons of production capacity anode material for lithium batteries - mesophase carbon microspheres (referred to as CMS). CMS project is a national 863 high-tech research and development projects, has been listed as a national high-tech industry demonstration projects.
