Title: PROCESS FOR COATING AN OXIDE MATERIAL
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 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 vessel of which at least one part rotates around a horizontal axis.
