Abstract: A solid-state method for recycling spent and/or scrap cathode material includes heating a cathode material comprising lithium nickel manganese cobalt oxide in an oxygen-containing atmosphere at a temperature T1 for an effective period of time t1 to convert the cathode material to a solid precursor, combining the solid precursor with a lithium compound, and heating the solid precursor and the lithium compound in an oxygen-containing atmosphere at a temperature T2 for an effective period of time t2 to form a product comprising monocrystalline lithium nickel manganese cobalt oxide having a formula LiNixMnyMzCo1-x-y-zO2, where M represents one or more dopant metals, x≥0.33, 0.01≤y
