Abstract:

With the large-scale decommissioning of lithium-ion batteries (LIBs), the secondary hazards of used batteries to the environment have become an urgent problem, and the recycling of valuable metals has received widespread attention and research. This paper reviews the latest progress in LIBs recovery processes, analyzes and summarizes the problems existing in recovery processes such as pyrometallurgy and hydrometallurgy. We focus on comprehensively analyzing and sorting out the current status of mechanochemical (MC) recovery of valuable metals in cathode materials, including study of mechanochemical techniques for recycling lithium iron phosphate (LFP), lithium cobaltate (LCO), lithium nickel manganese cobalt ternary (NCM), lithium manganese oxides (LMO), and other cathode materials, which provide references to the progress of the recovery process of LIBs.

Key words: lithium-ion batteries, mechanical chemistry, cathode materials, valuable metals

摘要:

随着锂离子电池(LIBs)大规模退役,废旧电池对环境的二次危害已成为一个亟待解决的问题,且其中的有价金属回收受到了广泛关注和研究。针对LIBs回收工艺的最新进展进行了综述,分析总结了火法冶金、湿法冶金等回收工艺存在的问题。重点对机械化学法(MC)回收正极材料中有价金属的现状进行全面分析和梳理,包括机械化学技术回收磷酸铁锂(LFP)、钴酸锂(LCO)、镍钴锰三元锂(NCM)、锂锰氧化物(LMO)等正极材料方面的研究,为LIBs回收工艺进展提供了参考。
