摘要
介绍了锂离子电池基本构造、工作原理及回收现状。详细阐述了当前研究中正极材料的主流回收方法,综述了废锂离子电池回收技术的研究进展,其中包括回收工艺发展、回收产品、对环境负担的影响,以及电池退役后的选择,如二次利用、直接再生修复电极材料、湿法或火法冶金回收材料等。从电池材料回收率,循环利用再生体系,电解液、隔膜和负极材料等综合回收方面对现有废旧锂离子电池回收处理与再利用技术提出了改进意见。
In the paper,the basic structure,working principle and recycling status of lithium−ion battery are introduced,and the main recycling methods of positive electrode materials are discussed in detail.The latest progress of waste lithium−ion battery recycling technology was reviewed,including the development of recycling process,the products recovered and the impact of recycling on the environmental burden,as well as the options for decommissioning ion batteries,including battery secondary utilization,direct regeneration and repair of electrode materials,hydrometallurgical or pyrometallurgical recovery materials.This study suggests several future research directions for recycling technologies that will help academics and policymakers take the necessary steps to achieve a circular economy in the lithium battery value chain.Improvement suggestions have been proposed for the existing recycling and reuse technologies of waste lithium−ion batteries in terms of battery material recovery rate,recycling system,comprehensive recycling of electrolytes,separators,and negative electrode materials.
