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.
