Abstract

Lithium-ion batteries (LIBs) are the most popular energy storage devices due to their high energy density, high operating voltage, and long cycle life. However, green and effective recycling methods are needed because LIBs contain heavy metals such as Co, Ni, and Mn and organic compounds inside, which seriously threaten human health and the environment. In this work, we review the current status of spent LIB recycling, discuss the traditional pyrometallurgical and hydrometallurgical recovery processes, and summarize the existing short-process recovery technologies such as salt-assisted roasting, flotation processes, and direct recycling. Finally, we analyze the problems and potential research prospects of the current recycling process, and point out that the multidisciplinary integration of recycling will become the mainstream technology for the development of spent LIBs.

废锂离子电池回收技术及未来发展方向

锂离子电池（LIBs）由于其高能量密度、高工作电压和长循环寿命而成为最受欢迎的储能设备。然而，由于lib中含有Co、Ni、Mn等重金属和有机化合物，严重威胁人体健康和环境，因此需要绿色有效的回收方法。本文综述了废锂回收的现状，讨论了传统的火法和湿法回收工艺，总结了现有的盐助焙烧、浮选、直接回收等短流程回收技术。最后，分析了当前废lib回收过程中存在的问题和潜在的研究前景，指出多学科整合回收将成为废lib开发的主流技术。
