摘要：
In recent years, with the “carbon peak”, “carbon neutrality” and other goals being proposed, new energy electric vehicles are developing rapidly, demand for lithium-ion batteries has soared. The use of a large number of lithium-ion batteries will also usher in the explosive elimination of lithium-ion batteries, resulting in a large number of waste lithium-ion batteries to be recycled. Lithium batteries can be roughly divided into four categories: NCM, LFP, LCO, LMO, the main recovery methods are pyrometallurgical technology and hydrometallurgy technology. In this paper, the research status of the recovery of the positive metal of lithium ion batteries in recent years was described, various processes were analyzed from many aspects, such as the difficulty of the process, the extraction efficiency of the target metal, and whether the pollution gas or waste liquid was generated to the environment. Finally, the advantages and disadvantages of different metallurgical processes were summarized and the future prospects were prospected. © 2024 Central South University of Technology.
