What are the differences between power lithium batteries and ordinary lithium batteries

　　Lithium ion batteries (hereinafter referred to as power lithium batteries) are chemical batteries that produce chemical reactions with lithium metal and oxygen. Because of its first component is lithium carbonate, it is also called lithium carbonate batteries. It has the advantages of high energy density, high power density, long circulation life, and low cost; it also has the shortcomings such as large volume (about 3 times the lead -acid battery) and heavy weight.

　　The use of power lithium batteries is widely used:

　　Electric vehicle power lithium batteries are mainly used for driving motors, used as energy storage equipment on pure electric vehicles; used as auxiliary power systems on hybrid vehicles; for other vehicles as spare power supply or mobile power stations. Global power lithium battery sales reached 47.75GWh in 2017, and it is estimated that it will exceed 50GWh in 2018. It is estimated that it will exceed 60GWh in 2019. It is estimated that by 2020, the output value of the global new power passenger vehicle will reach about 5 million vehicles

　　The proportion of pure electric models will exceed 80%. According to the statistics of the my country Automobile Industry Association, the output value of my country's new power passenger vehicles in 2017 was 794,000, with 879,000 units in 2018, and 599,000 vehicles in the first 10 months of 2019. In 2019, the growth rate of my country's new power passenger vehicles was about 30%, which was much higher than 23.3%in 2018. With the growth of electric vehicle sales in the future and the adjustment of the national subsidy policy, new power car companies in the "subsidy age" will face huge battles. Since 2018, mainstream domestic car companies have strengthened the R & D and production of ternary material batteries. After 2020, the advent of the subsidy age means that only companies that have mastered technical advantages survive and achieve rapid development and growth.
