废旧锂离子电池正极有价金属的分离和提取方法

Separation and Extraction Technologies of Valuable Metals from Spent Lithium-ion Batteries Positive Electrode Materials

介绍了废旧锂离子电池回收处理的意义和必要性,对溶剂萃取法、化学沉淀法、电沉积法、络合离子交换法等提取和分离正极中钴、铝、镍、锂等有价金属的研究现状进行了评述。

This paper introduced the importance and necessity of recycling spent lithium-ion batteries. The research progress of separating and extracting valuable metals （Co, Al, Ni, Li, etc.） from spent lithium-ion batteries positive electrode materials through solvent extraction, chemical precipitation, electrochemical deposition and complex ion exchange methods were reviewed.
