Abstract: Process for making an at least partially coated particulate material, said process comprising the following steps: (a) providing a particulate material selected from lithiated nickel-cobalt aluminum oxides and layered lithium transition metal oxides, (a) treating said cathode active material with a metal alkoxide or metal amide or alkyl metal compound in a fluidized bed, (b) treating the material obtained in step (b) with moisture in a fluidized bed, and, optionally, repeating the sequence of steps (b) and (c), wherein the superficial gas velocity in the fluidized beds in steps (b) and (c) decreases with increasing reactor height.
