Methods and systems for direct recycling and upcycling of phosphate-based cathode active materials

Abstract

Some embodiments are directed to systems and methods for direct recycling and upcycling of cathode materials. In one aspect, a method for direct recycling of cathode materials includes obtaining spent phosphate-containing cathode active materials (CAM). The method includes purifying the spent phosphate-containing CAM to obtain purified phosphate-containing CAM. The method also includes regenerating the purified phosphate-containing CAM to obtain regenerated phosphate-containing CAM. In some embodiments, the regenerating includes preserving a morphology and chemical composition of the purified phosphate-containing CAM. In some embodiments, the regenerating includes varying either one or both of the morphology and chemical composition of the purified phosphate-containing CAM.
