Abstract: The present invention is related to a process for making a coated oxide material, said process comprising the following steps: (a) providing a particulate material selected from lithiated nickel-cobalt aluminum oxides, lithium cobalt oxide, lithiated cobalt-manganese oxides and lithiated layered nickel-cobalt-manganese oxides, (b) treating said cathode active material with a metal alkoxide metal amide or alkyl metal compound, (c) treating the material obtained in step (b) with moisture, and, optionally, repeating the sequence of steps (b) and (c), wherein steps (b) and (c) are carried out in a vessel of which at least one part rotates around a horizontal axis.

Abstract: The present invention is related to a process for coating anoxide material, said process comprising the following steps: (a) providing a particulate material selected from lithiated nickel-cobalt aluminum oxides, lithiated cobalt-manganese oxides and lithiated layered nickel-cobalt-manganese oxides, (b) treating said cathode active material with a metal alkoxide or metal amide or alkyl metal compound, (c) treating the material obtained in step (b) with moisture, and, optionally, repeating the sequence of steps (b) and (c), wherein steps (b) and (c) are carried out in a mixer that mechanically introduces mixing energy into the particulate material, or by way of a moving bed or fixed bed, and wherein steps (b) and (c) are carried out at a pressure that is in the range of from 5 mbar to 1 bar above normal pressure.
