How does my country electric car battery technology route? From the technical type of lithium-ion battery, lithium iron phosphate is an important technical type of my country's powered lithium-ion battery, while the three-yuan materials and manganese are important for Japan and South Korea. From the tendency of technology development, the three-yuan materials will gradually replace lithium iron phosphate, and become the mainstream technology route for the future my country's powered lithium-ion battery. Before the second half of 2014, the lithium phosphate ion battery is the mainstream battery route for pure electric passenger cars.

Since the second half of 2014, in addition to BYD and SAIC, mainstream passenger car companies have applied three-yuan lithium-ion batteries to listing models, including Changan, FAW, Beiqi, Chery, Jianghuai and Zhongtai. These models of battery capacity are 20-30kWh, and life is 150-250km. From a global point of view, the development and processing of ternary materials is moving forward.

In this process, the performance of the material has been greatly improved, and the application field continues to expand. Japan and South Korea companies are the leadership of the three-yuan material battery. Domestic three-yuan materials processing starts around 2015, has formed a number of large companies.

The ternary material has excellent capacity, low cost, good safety, and has good development prospects in the field of dynamic lithium. High energy density, the cost of ternary material is relatively low, within 3-5 years, the three-dimensional material for power lithium-ion batteries will become mainstream, high-end three-yuan material power lithium-ion battery will not seek. The league is the mainstream battery of the sedan.

Since the large-capacity battery of the passenger car is high, the car company turns 3 yuan is generally cautious, because the bus is a fixed route, in order to improve the energy density is not an emergency passenger car, so The lithium-ion battery is still mainstream of passenger car batteries in the next three years. .
