A process for recycling degraded oxide cathode materials is disclosed. The process comprises comminuting degraded oxide cathode material under conditions to provide a substantially homogenised comminuted degraded cathode material. The comminuted degraded cathode material is then combined with stoichiometric amounts of one or more transition metal sources to replenish any transition metals in the mixture to provide a metal loaded comminuted degraded cathode material having a desired composition of transition metal elements. If the transition metal sources used in the preceding step are salts, the loaded comminuted degraded cathode material is sintered under conditions to produce an oxidised metal loaded cathode precursor material. The metal loaded comminuted degraded cathode material and/or the oxidised metal loaded cathode precursor material is then reacted with a stoichiometric amount of a lithium salt under conditions to provide a replenished lithium nickel manganese cobalt oxides cathode material.
