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.

Abstract: Process for making a partially coated electrode active material wherein said process comprises the following steps: (a) Providing an electrode active material according to general formula Li1+x, TM1+XO2, wherein TM is a combination of Ni, Co and, optionally, Mn, and, optionally, at least one metal selected from Al, Ti and Zr, and x is in the range of from zero to 0.2, wherein at least 60 mole-% of the transition metal of TM is Ni, and wherein said electrode active material has a residual moisture content in the range of from 50 to 1,000 ppm, (b) treating said electrode active material with a metal alkoxide or metal halide or metal amide or alkyl metal compound, (c) treating the material obtained in step (b) with moisture, (d) repeating the sequence of steps (b) and (c) twice to ten times, (e) performing a post-treatment by heating the material obtained after the last step (d) at a temperature from 200 to 400° C.
