Method & Evidence

AimTo develop and validate a rapid and efficient method for recovering and resynthesizing Lithium Nickel Cobalt Aluminum Oxide (NCA) cathode material from scrap waste.

MethodExperimental investigation and material synthesis.

ProcedureThe study involved leaching of NCA cathode scrap using strong acids (HCl, H2SO4, HNO3) at high solid loading rates, followed by co-precipitation of mixed metal hydroxides. The precipitated material was then heat-treated to resynthesize NCA. The efficiency of metal leaching and the properties of the recycled NCA (RNCA) were analyzed, including its crystalline structure and electrochemical performance in a full cell.
