Regeneration of LiNi_1/3Co_1/3Mn_1/3O₂Cathode Active Materials from End-of-Life Lithium-Ion Batteries through Ascorbic Acid Leaching and Oxalic Acid Coprecipitation Processes

One of the emerging issues in solving the electronic waste problem is to address the growing amount of end-of-life Li-ion battery (LIB) waste. In this work, the regeneration of LiNi1/3Co1/3Mn1/3O2 (NCM 111) cathode active materials from end-of-life LIBs was successfully carried out via an easy, fast, and environmentally friendly recycling process that comprised three main stages, i.e., ascorbic acid leaching, oxalate coprecipitation process, and...
