Lithium-ion battery is currently on the market the most common energy storage technology, widely used in a variety of personal electronic products, mobile devices and even electric car battery. Usually we say Lithium Battery that lithium-ion batteries, according to the general use is divided into energy storage Lithium Battery and power Lithium Battery. Energy storage battery is generally used in electric vehicles, the internal resistance of small, charge and discharge speed, generally can reach 3 ~ 5C, the price is about 1.5 times more expensive than the energy storage battery.
Energy density, power density, safety performance, charging time, environmental protection and high temperature is the evaluation of lithium battery performance of the five indicators, China's lithium battery technology has been initially four points, but in the energy density on the need for further sophisticated technology, Waiting for progress. March 1, 2017, the Ministry of Industry, Development and Reform Commission, Ministry of Science and Technology and the Ministry of Finance four ministries jointly issued the "promotion of automotive power battery industry development action program", "program" requires power battery key materials and spare parts made a major breakthrough. By 2020, positive and negative, diaphragm, electrolyte and other key materials and parts to achieve world-class level, the upstream industry chain to achieve balanced and coordinated development, the formation of a core competitiveness of the innovative backbone enterprises. The program for the battery than the energy requirements will inevitably lead to a new round of high energy density material boom.
The current hot lithium titanate material is also worthy of attention. It can replace graphite as a negative material. Although the energy density is not high, but the lithium titanate can make the battery to achieve high magnification charge and discharge, and excellent safety performance, long cycle life. It is reported that Yin Long is now developing the fourth generation of high-energy density lithium titanate battery, compared with the third generation cost reduction of 40%, energy density increased by 60%. Industry optimistic that the future of lithium titanate battery may be with the three yuan lithium battery and lithium iron phosphate battery to form a three pillar of the situation.
Although the high cost of lithium-ion battery industry is facing serious challenges, but many companies have been committed to improving the cost-effective lithium-ion battery. According to EnergyTrend analyst Duff (Lv Li Shun) on the price of lithium battery analysis results, lithium battery prices in 2017 the first, second and third quarters have a little rally, but overall, in recent years with the market for Lithium Battery Demand continues to expand, mass production of Lithium Battery, the cost is declining year by year, the current price is sufficient to be commercial development and extensive use.
In addition, the power lithium battery attenuation to the initial capacity of 80% or less, you can use the energy storage area, further reducing the cost of energy storage Lithium Battery.
