Study on Recycling and Reuse of Waste Battery of Electric Vehicle

摘要

In recent years, with the rapid development of the electric vehicle market, the number of waste lithium ion battery has also risen rapidly. The waste lithium ion power battery contains a lot of toxic and harmful substances, so it is of great significance to recycle and harmless treatment. This paper summarizes the main processing of waste lithium ion battery, including three steps: pretreatment, two treatment and deep treatment. Among them, the two processing and deep processing steps are the core part of the whole process, which has the greatest influence on the recovery effect of the whole battery. Finally, through the comparison of the main wet process and fire process, the process of treating waste lithium ion power battery with wet process and fire method is put forward, and the development direction of the waste lithium ion power battery recycling technology in the future is prospected.
