ZERO WASTE CLOSED-LOOP GREEN LITHIUM-ION BATTERY RECYCLING

A method for recycling catalytic metals comprising: collecting a plurality of spent catalytic metals, wherein the spent catalytic metals contain cathodes of NMC111, NMC622, NMC811, NCA, LCoO, LiNi0.5Mn1.5O, LiMnO, LiNiO, LiMnO, and/or LiMnOcompositions; subjecting the plurality of spent catalytic metals to a green mixture, wherein the green mixture includes dihydrogen phosphite and water, phosphoric acid and water, sulfuric acid and water, hydrogen chloride and water, or nitric acid and water, at temperatures of between 80 and 120° C. to form a metal leachate solution; and recovering lithium (Li) from the metal leachate solution.
