摘　　要：提升废旧动力电池再生利用水平是“十四五”循环经济发展规划的重点任务,对保障国家能源资源安全具有重大意义。目前,三元锂废旧电池再生利用率仅约22.5%,磷酸铁锂废旧电池几乎没有再生利用。本文介绍了动力电池市场发展与报废回收现状、再生利用的资源与经济价值,综述了企业产能、技术现状与存在问题,重点分析了主要技术经济问题。高杂质、低浓度锂盐溶液提锂技术创新,三元锂废料选择性优先浸锂方法研究,有助于实现废旧电池提锂技术产业化。It is a key task of the national 14th Five Year Plan for the development of circular economy,to improve the recycling level of waste power batteries,which is of great significance for ensuring national energy and resource security.At present,the recycling rate of the waste ternary lithium batteries is less than 22.5%,and there is almost no recycling rate of the waste lithium iron phosphate batteries.The market development and recovery status of the power batteries,the resources and economic values,as well as the enterprise production capacity,technological status and problems of the battery recycling,were mainly introduced.The current technology and its economic analysis were focused on,to recommend that technical breakthroughs of lithium extraction from the solution of high impurities and low concentration lithium,as well as method research of the selective leaching of lithium for ternary lithium waste,would contribute to the industrialization of lithium extraction from waste batteries.
