低共熔溶剂浸出废旧锂离子电池正极材料中的有价金属

Deep eutectic Solvents for Leaching Valuable Metals from Spent Lithium-ion Batteries Cathode Materials

锂离子电池优良的工作性能使其应用越来越广泛,随之产生的废旧锂离子电池的数量也逐年增加。废旧锂离子电池若不能得到及时的处理,一方面会对环境带来极大的危害,另一方面废旧锂离子电池中有价金属的回收能够有效缓解锂离子电池生产中资源短缺的问题。本综述详细介绍了低共熔溶剂在回收废旧锂离子电池正极材料、负极材料、铝箔的优点以及对未来的展望。

The excellent working performance of lithium-ion batteries makes them more and more widely used,and the number of spent lithium-ion batteries is also increasing year by year.If spent lithium-ion batteries cannot be treated in time,on the one hand,it will bring great harm to the environment.On the other hand,the recovery of valuable metals in spent lithium-ion batteries can effectively alleviate the shortage of resources in the production of lithium-ion batteries.In this review,the advantages of deep eutectic solvents in recycling cathode materials,anode materials and aluminum foils of waste lithium-ion batteries are introduced in detail,and the future prospects are also discussed.
