摘 要: 基于“Web of Science核心合集”和引文分析软件Citespace，对退役锂电池回收领域的研究概况、热点及演进趋势进行分析。结果表明：该领域正处于快速发展阶段，中国已出现数家强势研究机构，形成了优秀的科研团队，成果产出和影响力均处于世界领先地位，但跨地区、跨机构的科研合作还需继续加强。目前退役锂电池回收的研究热点集中在金属湿法富集/提取工艺研究、电极材料解离分析研究、资源循环可持续研究三大方向。经过10年不断发展，该领域逐渐实现前期预处理、有价资源综合回收、回收产品资源化利用的闭环工艺体系。该领域将朝着资源综合利用、经济效益与生态环境保护协同推进的方向继续发展。

Abstract:A detailed knowledge map analysis of documents related to the recycling of waste lithium-ion batteries situation, focus and trend was carried out based on the ‘Web of Science Core Collection’ database and software Citespace. The results show that this field is in a stage of rapid development. China has many powerful research institutions and excellent teams. Their research achievements and influence are both in the leading position, but thecross-regional and cross-institutional cooperation still needs to strengthen. The research focus is concentrated in three directions: hydrometallurgical concentration and extraction process, electrode material dissociation analysis and resources recycling and sustainable research. For ten years of continuous development, this field gradually realizes the closed-loop system of pre-treatment, valuable resources comprehensive recovery, and recycled product resource utilization. The field will develop in the direction of comprehensive utilization of resources, economic benefits and ecological environmental protection.
