Electrode Material Recovery Mode and Economic Analysis of Lithium-Ion Power Battery

Lithium-ion batteries in China will soon enter the tide of decommissioning. It is of great significance to deal with the used batteries reasonably for environmental protection and resource utilization. In this paper, the technology of dry and wet recovery of electrode materials which was widely used in the market was introduced. According to the investigation and analysis of the production cost and the income data of the recovery process, the economic profit obtained was calculated and analyzed. Results showed that the wet recovery technology of ternary material batteries was more economical, while the recovery of lithium iron phosphate batteries was profitable with improved dry recovery technology.
