Recycling of used power batteries

In recent years, the rapid development of China's new energy vehicle industry has also led to the rise of many industries upstream and downstream of the industry chain. According to incomplete statistics, as of 2018, China has been at the top of the global new energy vehicle production and sales list for four consecutive years. At present, the number of new energy vehicles in China has exceeded 2.2 million, with more than 140 GWh of power batteries assembled, and the development of the power battery industry has advanced by leaps and bounds. However, at the same time, the issue of power battery decommissioning and recycling is also testing the development of the industry. It is understood that since 2019, China's new energy power batteries will gradually step into the scale of the retirement wave.


Wang Wei, assistant director of Shenzhen New Energy Vehicle Application Promotion Center, has said that it is expected that by 2020, China's retired power batteries will reach a total of about 25 GWh, and the retired power batteries are mainly concentrated in the Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta regions where new energy vehicle ownership is large. It is reported that when the battery capacity decays to less than 80% of the rated capacity, the power battery will no longer be suitable for electric vehicles and can be shifted to the field of secondary use. According to the power battery capacity, 100% to 80% of the capacity meets the car power use, 80% to 20% of the capacity meets the secondary use, and below 20% of the capacity is subject to end-of-life recycling.

Once the power battery enters the end-of-life recycling process, if these waste batteries are not properly disposed of and allowed to enter informal circulation channels, it will have many adverse effects on the environment and public safety. If not properly disposed of, used power batteries will pose safety hazards such as electric shock, explosion and corrosion, posing a greater threat to the ecological environment and personal health. At the same time, the lithium, nickel, cobalt, manganese and rare earth metals contained in used power batteries, if not fully recycled, will also greatly cause a waste of resources.
Recycling enterprises accelerate the binding of channels to seize the recycling entrance

As a vital part of the new energy vehicle industry chain, the market for power battery recycling is not yet mature, and many power battery recycling companies are growing in exploration. Power battery recycling field has not yet appeared iconic leading enterprises, but the future market dividend is still clearly visible, many capital and power battery-related enterprises have been aimed at this piece of cake, competing to layout the power battery recycling field, in advance to seize the f
In recent years, some listed companies have increased their efforts in the field of power battery recycling and have been running around, taking the lead in binding high-quality used power battery channel resources before the outbreak of power battery decommissioning, accelerating the expansion of power battery recycling direction of business, seizing the recycling entrance and establishing a good brand effect. Previously, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, the Ministry of Environmental Protection, the Ministry of Transport, the Ministry of Commerce, the General Administration of Quality Supervision, Inspection and Quarantine, and the National Energy Administration jointly issued the "Interim Measures for the Management of New Energy Vehicle Power Battery Recycling" has also been clearly put forward, will continue to encourage automobile manufacturers, battery manufacturers, end-of-life vehicle recycling and dismantling enterprises and comprehensive utilization enterprises through a variety of forms, cooperation and common The recycling channels for waste power batteries.

The cooperation between power battery recycling enterprises and car enterprises and battery manufacturers is getting closer and closer, such as Hunan Bump and BMW, Greenmax and BYD and Beiqi Penglong, Ganzhou Haopeng and BAIC New Energy, etc. Guanghua Technology is in a short period of time quickly and Guangxi Huaao, Nanjing Golden Dragon, Chery Wanda, Wuzhoulong Automobile and many other car enterprises to establish a partnership, in the field of power battery recycling to start a series of strategic cooperation.

Alleviate the high external dependence of upstream resources

Waste power batteries are rich in valuable metal resources such as lithium, nickel and cobalt, and the recycling of power batteries is vital to the effective realisation of resource recycling. A comprehensive power battery recycling system is important for effectively reducing battery production costs, avoiding the risks of upstream raw material scarcity and price fluctuations, and ensuring the healthy and stable sustainable development of China's new energy vehicle industry.
