Summary:Process for the recovery of transition metal from cathode active materials containing nickel and lithium, wherein said process comprises the steps of (a) treating a lithium containing transition metal oxide material with a leaching agent (preferably an acid selected from sulfuric acid, hydrochloric acid, nitric acid, methanesulfonic acid, oxalic acid and citric acid), (b) adjusting the pH value to 2.5 to 8, and (c) treating the solution obtained in step (b)with metallic nickel, cobalt or manganese or a combination of at least two of the foregoing.
