Abstract:The steadily growing lithium-ion batteries (LIBs) market brings the critical question of the future treatment of tremendous waste from end-of-life (EoL) LIBs. Therefore, recycling of EoL LIBs has become an urgent need to overcome the foreseen environmental and economic challenges. Herein, we propose a direct recycling process to regenerate NCA cathode active material (CAM) from spent LIBs. A gentle heat pretreatment at a low temperature is applied to facilitate the recovery of the CAMs. The cathode strips from… Show more
