At present, there are two main technical routes for Chinese lithium battery industry, one islithium-ion ferrous phosphatebattery, one is lithium manganate battery. Each technology route has advantageand disadvantage. Lithium manganate battery is started early, technology is relatively mature, the weakness is short battery life, full charge and discharge is 2000 times, and high temperature resistant performance is poor. Lithium-ion ferrous phosphatebattery is the technical route that domestic enterprises always adopt at present, the weakness is that the two core technologies of a patent one is in U.S. and one is in Canada, and China develop the lithium-ion ferrous phosphate cannot avoid these two core technologies, thus there has intellectual property concerns.
Low temperature resistant performance is poor, material consistency control is difficult.Anyway, lithium battery technology route should be determined by the market mechanism, development trend should be high security, long life, lightweight, low prices.
About the existing problems in the development of lithium battery industry, mainly include: one, strategic positioning is wrong.Speaking of lithium batteries, we always think about the electric cars, in fact, the electric cars just have a part of 兴发娱乐xf938-Application field of the lithium battery. Lithium-ion batteries are widely used in communication power supply, electric cars, wind energy, solar energy, smart grid and other storage power station,not just the electric car parts, and the scientific planning should not be placed underthe science and technology ministry of the electric car, and should be single listed. Two, management system is not clear. Vast majority of small and medium-sized enterprises produce lithium-ion batteries, and industries chaos and unhealthy competition. Lack of management department, included in the industry ministry cannot sure which department will charge. Three, Lack of standard system. Even to say there is no standard for the lithium battery industry.Now the lithium battery production enterprises design the products according to the requirements of customers, the shape is diverse. A set of model costs hundreds of thousands, and a lot of model is only used once that caused great waste. Testing project is unreasonable, and testing cost is so high.
Lithium-ion batteries are widely used in information,energy, transportation, military and other fields.Great 兴发娱乐xf938-Application spacewill produce a great demand for lithium resources in the future.In recent years, thedemand of global market for lithium batteries increased by an average of 20%. About 40,000 tons of lithium productsconsumption in 2009 (lithium chemical products and metallic lithium), 80% is lithium chemical products consumption in various 兴发娱乐xf938-Application fields, 20% is used in alloy, ceramic and glass industries. Consumption of lithium resources grows in all areas with different range, it will transform from the "industrial monosodium glutamate" to "energy metal".
China is the great power of lithium resources, 兴发娱乐xf115-Storage Energy of lithium resources is 1.1 million tons, output is 3500 tons in 2008.Salt lake lithium brine is mainly distributed in Qinghai, Tibet, Hubei and other places, lithium ore is mainly distributed in Sichuan, Jiangxi, Hunan, Xinjiangand other places. With the further promotion of electric vehicles, the demand for lithium has risen sharply, the battery industrywill become the largest market of lithium carbonate in the future.Therefore, China should project lithium development from the strategic resources stage.
Lithium battery has advantages of high density, no memory, high conversion efficiency, light weight, long service life, no pollution, and its costs is lower thanlead-acid batteries from the whole life cycle.As a result, power lithium batteries will become the development direction of a new generation of power battery.
