Abstract
Disclosed herein are embodiments of systems and methods for recycling used solid feedstocks containing lithium powders for use in lithium-ion batteries. The used solid feedstocks may be Lithium Nickel Manganese Cobalt Oxide (NMC) materials. In some embodiments, the used solid feedstock can undergo a microwave plasma process to produce a newly usable, lithium supplemented solid precursor with augmented chemistries and physical properties.
