废旧锂离子电池湿法冶金回收工艺进展

Progress in Hydrometallurgical Recovery Process for Spent Lithium-Ion Batteries

废旧锂离子电池中含有大量的钴、镍、锂等有价金属,具有非常高的回收价值。本文综述了废旧锂离子电池的湿法冶金回收工艺,包括预处理、有价金属浸出和有价金属分离提纯等,最后对废旧锂离子电池湿法冶金回收工艺进行展望。

Spent lithium-ion batteries contain a large amount of valuable metals such as cobalt,nickel,and lithium,and have a very high recycling value.In this paper,the hydrometallurgical recovery process of spent lithium-ion batteries is reviewed,including pretreatment,valuable metal leaching,and valuable metal separation and purification,and finally the hydrometallurgical recovery of spent lithium-ion batteries is prospected.
