The rapid progress of the lithium battery industry has supported the improvement of the overall performance and competitiveness of electric vehicles. Driven by both policy and market, the new energy vehicle and power battery markets are more than a match for each other. However, at the same time, China's power battery market also appeared supply tension and overcapacity coexist phenomenon.

Data show that in 2017 China's power battery production capacity has exceeded 200GWh, but the overall capacity utilization rate is only 40%, the market polarization is very obvious, the supply of high-end high-quality production capacity is insufficient, the low-end production capacity is under-ordered, the production and operation is difficult, showing a structural overcapacity.

Globalization of power battery competition is becoming increasingly fierce, Chinese companies will gradually expand from the domestic market to the international market, and Japanese and South Korean companies will further to the Chinese market, China will become the main battlefield of the power battery competition, Europe and the United States, although the companies in this round of competition has lost its position, but they have already been in the next stage of the competition to do the layout is potentially a strong competitor.
