Shaolin car has developed three types of models, the initial plan this year, production of 2000 units, and gradually developed into 5,000 units.

Electric Vehicle Program China First Tractor is in the early preparation.

January 24, the provincial government takes the initiative in creating the League of Henan electric vehicle industry. At the meeting, provincial director of the Office of Industry and Information Sheng Yang Tao, Zhengzhou, Henan based on four major auto manufacturers (hippocampus, Yutong, Nissan, Shaolin) to build the production base electric vehicles in the five major M8403 A1079 battery manufacturers have Xinxiang (Golden Dragon, Universal Group, the electricity of the air lithium, etc.) to build electric car production base of batteries. The eventual realization of “equipment, equipment, Henan, Henan” goal. After passing through the bottleneck techniques, ran on the Central Plains will be built in Henan are electric vehicles.

Solid reaction method of state was used with lithium, iron, phosphate salts as raw materials, raw materials grinding dry, baked at high temperatures in an inert atmosphere or reducing to a certain temperature to accelerate heating temperature, reaction time after cooling to produce the necessary powder iron phosphate lithium Sony VGP-BPL8 Sony VGP-BPL8A. Our core technology is the use of mixed ion doping process (Fig. 1) and liquid carbon coated technology. Lithium iron phosphate through the iron fence put up little silicon, the introduction of oxygen potential of fluorine, chlorine, sulfur and other elements doped, resulting in a lithium-ion Holidays, substantial increase in the conductivity of iron phosphate bulk lithium ion, one stroke solve the iron phosphate lithium large magnification poor performance, poor low temperature performance gaps.

With “liquid carbon coating” process, effectively improve the distribution of particle surface morphology LiFePO4 and carbon, has considerably improved the electronic conductivity of LiFePO4 and achieve its nano-particle technology.

Get this powder process of lithium iron phosphate has the following structural parameters: D10 ≥ 0.8μm; D50 ≈ 2.00 ~ 3.00μm; D90 ≤ 20μm; tap density of 0.8 ~ 1.0 g/cm3 and that the area of 18 ~ 20 m2 / g, the morphology of micro-enterprises, see electron microscopy. Showed a spherical particle, the particle size of 200 ~ 500nm, the second spherical particles, dispersion, excellent with an average particle size of about 2 ~ 3μm. Vostro 1500 battery Vostro 1700 battery

As the electronic conductivity of lithium iron phosphate and ionic conductivity have been greatly improved, so the battery displayed an excellent performance. 2032-half of such cells, 0.2C on the following capacity to 145mAh / g, 0.2 ~ 10C under the voltage drop of only 0.25 V, the capacity fell only 25mAh / g , 10C, 300 cycles, the retention capacity was 95%;

Phosphate LiFePO4 cathode material, among others, Li3V2 (PO4) 3 is also good for security and electrochemical properties are also ideal, is to become the EV and HEV Li-material ion battery cathode. Li3V2 (PO4) 3 with monoclinic structure, and its relatively high ionic conductivity compared to LiFePO4, but its electronic conductivity is still low, usually through carbon coated to improve its electronic conductivity. We are prepared using solid phase reaction of carbon coated Li3V2 (PO4) 3, respectively, and citric acid (citric acid), sugar (glucose), polyvinylidene fluoride (PVDF) and starch (starch ) as the pyrolytic carbon reduction after the agent, excessive carbon may also act as agent driver. Finally found that the use of citric acid powder obtained has a high capacity to 3.0-4.3V at 0.2C charge and discharge, the availability of 118mAh / g reversible capacity, and not after 100 cycles the capacity decay, obtained from the PVDF powder magnification excellent performance in the discharge 5C under magnification will always be able to reach 95mAg / h capacity.

3 high anode material securities – the materials anodic oxide metal

Calorimetry studies have shown that metal oxides such as Li4Ti5O12, Fe2O3, so that the graphite anode shows better thermal performance security. Li4Ti5O12 because of the good structural stability known as the zero material strain, high load and platform discharge (1.5 V vs. Li + / Li) to match the thermal reaction of the electrolyte compared to the reaction Lithium intercalation of graphite with the electrolyte from the heat much more relaxed, and can reduce the transport of ions through nano-based way to improve the performance of battery power, so this material also showed the power of Battery broad application prospects, is expected for high density power system battery.

By thermal polymerization of acrylic acid were prepared nano-powders Li4Ti5O12, the powder sintered at 750oC average particle size of 120 nm, good performance of the electrochemical properties of the loop 100 times, the reversible capacity is still as high as 160 mAh / g, but also in the 10C Under the flow can reach 122 mAh / g capacity.

To facilitate industrialization, we have also been achieved using solid-phase synthesis of Li4Ti5O12, due to lack of access to the nanoscale solid phase method of powder to obtain a magnification of good performance, we use the name of the composition of Cu-doping to prepare Li4Ti5CuxO12 powder X +, and get the best composition of x = 0.15 when the powder Li4Ti5Cu0.15O12.15, this material contains two types of structure spinel, namely Li4Ti5O12 and Li2CuTi3O8 first lithium intercalation process, Li2CuTi3O8 through the following reactions produce the same quality of Cu, Cu resulting uniformly distributed in the electrode, the electrode significantly increased the electronic conductivity, thus improving performance of battery power.

Li2CuTi3O8 + 2 Li = 0.6 Li4Ti5O12 + Cu + 0.8Li2O

Nano metal oxide transition as anode materials for lithium-ion batteries can significantly improve the battery charge or discharge capacity and performance of the new generation of lithium-development of ion battery in a direction important, with good development prospects. We have developed a simple synthetic method and practice – the heat curing acrylic, and particle size were prepared using this method, homogeneous and nano-Fe2O3 nano-composite Fe-oxides Li By optimizing the precursor liquid formulations, the calcination temperature, electrode formulation and so on, we have prepared a good electrochemical performance of nano-Fe2O3-based anode for lithium-ion G5266 HD438 battery after 200 cycles, the electrodes were able to meet that capacity 1300mAh / g or more. And we use it for industrial batteries, through testing short-circuit the negative than the usual graphite anode has a better safety performance.

4 The high-security system of the electrolyte

Electrolyte contains high activity of flammable organic solvents led to lithium-security issues of Ion battery is an important reason, developing the electrolyte of high security, to solve its security problems are the most direct and effective. As of dimethyl methylphosphonate (DMMP) has a higher than the TMP and other phosphorus content of phosphate, should be more efficient flame retardant, DMMP high viscosity and low dielectric constant possible to ensure that the electrolyte electrochemical performance is not affected, while the low freezing point most likely to improve properties of existing low temperature electrolyte, in addition to the price advantage DMMP widely used to increase their weight.

. This electrolyte at low temperatures showed more than usual electrolyte (1M LiPF6/EC + DEC (1:1 wt.)) A higher conductivity in the cathode half cell LiCoO2/Li established a greater discharge capacity and better performance at low temperature. PP2182L HSTNN-LB31

DMMP compatibility problems even though it may be, and, like many other additives, it is extremely difficult, and graphite negative, but more effective flame retardant in reducing the amount of fire retardant characteristics to facilitate the contradiction between the graphite-compatible and can be adopted (1) The use of modified graphite surface, (2) and forming compound additive are two ways to resolve this contradiction. By adding 5% of film forming electrolyte additives, vinyl ethylene carbonate (VEC), the electrolyte and the spherical MCMB graphite and amorphous carbon-coated graphite (SMG) of the compatibility between the marked improvement in LiCoO2 / MCMB and LiCoO 2 / SMG best performance throughout the performance of the cell cycle, LiCoO2 / SMG full battery in the loop 50 times, the capacity retention rate of 82% or more.

Structural stability of the anode and the DMMP-based electrolyte Li4Ti5O12 there is greater stability, we Li4Ti5O12 the LiNi0.5Mn1.5O4 with 5V cathode material with the formation of a new 3V battery, using the aforementioned high DMMP security based on the electrolyte in the absence Canadian film-forming additives which may be more compatible with the positive and negative electrodes, and demonstrated throughout the cell may be comparable to the performance of conventional battery electrolyte, which for High security in the use of the anode electrolyte lithium titanate power the field of batteries and battery energy storage to display a broad application prospects.

Accelerate technological upgrading and product updates, held in Beijing recently loudest voices of the Ninth China International Battery Fair. Experts say some Chinese still need to improve product quality, VGP-BPS2A VGP-BPS9A batteries need to upgrade industrial technology, the electric vehicle batteries, zinc-manganese batteries urgent need to adjust the product structure.

The experts also said, my batteries are very dependent on international markets, particularly in solar cells, more than 95% of exports, 90% dependent on imported raw materials, “two thirds” Market risk is too high but have also created nonprofit industry-shifting. Relatively backward industrial base of raw materials, key materials still rely on imports, high energy consumption of China and the high pollution in exchange for only a very low cost effectiveness. Such as manufacturers of solar cells, the average profit margin is only 8% if the deduction of tax rebates on exports, the core business unprofitable.

Battery Industry is an overall advantage of traditional industries, but with new materials, new processes, new technological developments, the battery industry is increasingly one of the emerging industries in high technology. According to reports, in recent years the development of the battery industry, China has shown the following characteristics: production has steadily improved, the rapid export growth, technological progress, accelerated product structure more reasonable, diversified companies, the large-scale development, and equipment levels gradually increased, overall strength improved markedly. Battery industry has also led to the development of electronics in China, not non-ferrous metals, chemicals, mining, machinery and other related industries, construction in the national economy has played an important role.

The survey showed that nearly five years, sales of batteries from China more than 20% rate of annual growth rate of output growth of about 10%, well above the world average. In the past, my batteries low in the main traditional products now mercury-free alkaline manganese batteries, lithium batteries, sealed maintenance-free valve-regulated lead acid batteries, solar cells Dengjun experienced rapid development. That industrial restructuring in the world in recent years, China is developing in the global battery production, processing and commercial center, is the world’s leading producer of batteries.

However, by the international financial crisis since the second half of 2008, China’s commercial battery industry growth rate of exports has continued to decline, sales of batteries accounts receivable to increase, the economic decline . While mobile phones, cars, electrical bicycle battery accessories such as the contraction in output and sales volume, the growth rate of production of the battery decreases. Some staff members to participate in the show business of the company, now face the plight of battery cost increases are mainly caused by the less competitive market, corporate profits have fallen sharply.

China Light Industry Information Center, according to parties involved in the first quarter, China’s battery industry as a whole race showed the following characteristics: Although the output of a recovery in manufacturing growth above battery designated output size of 9.87 percent over last year, but the international market, depressed the first quarter exports battery last year fell by 31.86 percent against. The toys affected by the export trade, the fourth button cell alkaline manganese exports continued to decline, the cylindrical cell alkaline manganese export volume decreased slightly, other alkaline manganese batteries to accelerate the decline of exports. At the same time, business costs, lower profits. 1 ~ 2 months of this year, the battery industry, these enterprise-wide total profit fell 68.78 percent, the battery industry, these enterprise-wide face a loss of about 31.19 %, total loss of 7.85 billion yuan, compared with losses last year rose 215.78%. And the expansion of trade deficits, corporate operational difficulties. Effects of tax adjustment of China’s export rebate policy is not yet clear, but the green barriers abroad, the impact of the battery industry in China continues. According to the Official Journal of the EU “directives issued by the batteries, batteries lead, cadmium, mercury objective fact, more demanding and requires commitment fees for cost recovery. REACH Regulations and guidelines to improve the registration fee of battery charge and ROSH test, the substantial increase in cost of battery production and marketing costs for export, some companies have been for economic reasons and technical reasons, to abandon foreign markets. hp Pavilion dv2000 battery  hp Pavilion dv6000 battery

Currently, the battery industry in China is facing an industrial upgrading overall. China Battery Industry Association, said the Secretary-General Wang Jingzhong, recently adopted the “restructuring of light industry and the revitalization of the planning will contribute to the restructuring of the battery industry and industrial modernization. The battery industry should take this as an opportunity to work for the localization of technical equipment to make significant progress and has formed a group with strong international competitiveness of key enterprises, so that the national product and market development The value added of exports significantly improved, more diverse marketplace. While promoting the largest producer of electric vehicles, power tools power from the battery to form a new industrial scale, making China the world of rechargeable batteries, the solar cell production to maintain the global leader and accelerate market development and gradually alleviate the shortage and the variety of low battery increase exports, improve product quality and value. “Strengthening the internal force is the key.” Jingzhong Wang said. PA3383U-1BRS PA3395U-1BRS

According to reports, the next few years, the Chinese battery industry will accelerate the technological upgrading and product upgrades to improve effectively the risks of industry resistance capacity and international competitiveness, and strengthen the capacity of independent innovation and strengthening the brand, a perfect business system to support innovation, and the subsequent implementation of the technology and equipment domestic production, diversifying markets for accelerate industrial battery manufacturing power in the world in a global manufacturing power forward. Physics, Chinese Academy of Sciences, experts said the creation of the National Research Center for the battery industry, the integration of the industry to improve the capacity of independent innovation, promote the industry, technological advances, we should focus on progress in electric vehicles, vehicle batteries and battery materials, key technologies and key research and industrialization. Chinese market for electric bicycles to developing lithium-ion battery industry has provided opportunities. “Electric vehicle battery is the most critical components, but also brings together multi-disciplinary results of scientific research, companies need the government to focus on a selection of high quality support.” In the exhibition, many companies made such a request.
