Due to the development of new energy vehicle industry, the global power battery industry is developing rapidly. According to iiMedia Research, the global installed capacity of power batteries reached 92.5GWh in 2018, up 45.8% year on year. The market share of the world's top ten power battery enterprises reached 88.7%, and Ningde times, Panasonic and BYD have occupied the top three positions in the market for two consecutive years. Meanwhile, China's power battery industry has entered a stage of rapid development. In 2018, the scale of China's power battery market has exceeded 82 billion yuan, and China's power battery market is highly concentrated. The installed capacity of top ten enterprises has reached 83.2% of the total. As a derivative industry of the power battery industry, China's battery recycling industry is at the initial stage, and has formed two models of producer-led recycling and professional third-party recycling. In general, the automobile power battery industry presents four trends: first, the production and sales volume continue to grow rapidly, and the industry concentration increases in the competition; Second, the sales price of power battery system has been greatly reduced, and the upstream material has become a key factor; Third, the development of power battery is good, but the frequent occurrence of negative events is still worrying; Fourth, the recycling route of power batteries is becoming clearer, and the commercial system still needs to be improved.
