Li-ion battery recycling will become critical to the management of end-of-life batteries from electric vehicles. Currently, it is a challenge create profitable process, which made more difficult by reduction in cathode cobalt content. Maintenance structure throughout process can yield increased revenues that may make profitable. This method require careful removal PVDF binder and carbon black, be achieved through thermal processing. It necessary mitigate effects fluorine on material. Herein, we report utilizes excess LiOH·H2O react with this thereby prevent lithium doping In addition, demonstrate one-step both remove relithiate
