The present invention is related to a process for coating an oxide 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 or metal halide or metal hydride at a pressure that is in the range of from 5 mbar to 1 bar above ambient pressure, (c) deactivating the material obtained in step (b) with a moisture or a HF containing gas at ambient pressure, wherein step (b) is carried out in a mixer that mechanically introduces mixing energy into the particulate material, or by way of a moving bed or fixed bed. |
