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.

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.
