The recycling of Li(Ni 1/3 Co 1/3 Mn 1/3 )O 2 (NCM) and LiCoO 2 (LCO), which are cathode materials for Li-ion batteries, was demonstrated via a chlorination-based Li extraction technique. The recycling process follows a chlorination - washing/filtering - drying - mixing - re-synthesis process. Aroun...
