| 中文摘要: |
| 锂电池新能源汽车行业快速发展，大量含有贵金属的废旧锂电池（LIBs）进入退役期。目前废旧锂电池预处理及有价金属回收技术面临能源消耗量大、电池种类泛化性弱等问题。本文介绍了锂电池生命周期、组成及失效机理，综述了国内外废旧锂电池预处理及有价金属回收技术现状。总结了目前预处理技术中放电、破碎及分选工艺的不足，分析了有价金属回收再利用技术中湿法冶金和火法冶金回收工艺的优缺点。提出了废旧LIBs预处理方法和有价金属回收技术的研究方向。 |
| 英文摘要: |
| With the rapid development of the Lithium-ion batteries new energy vehicle industry, a large number of used Lithium-ion batteries (LIBs) containing valuable metals have entered the decommissioning period. At present, the pretreatment methods and valuable metals recycling technology for used LIBs are faced with the problems such as large energy consumption and insufficient generalization of battery types. This paper introduces the life cycle, composition and failure mechanism of LIBs, and summarizes the current situation of pretreatment and valuable metal recycling technology of the used LIBs at home and abroad. The shortcomings of discharge, disassembly and separation processes in current pretreatment technologies are summarized, and the advantages and disadvantages of hydrometallurgy and pyrometallurgical recovery processes in valuable metal recycling technologies are analyzed. The research direction for the pretreatment method and valuable metal recycling technologies of the used LIBs are proposed. |
