Abstract: The present invention relates to an apparatus for coating particles by atomic layer deposition comprising (a) a first reactor capable of bringing particles in contact with a first reactive gas and (b) a second reactor capable of bringing particles in contact with a second reactive gas, wherein the first and the second reactor are separated by a first and a second gas lock and the particles can be conveyed from the first reactor through the first gas lock to the second reactor and at the same time the particles can be conveyed from the second reactor through the second gas lock to the first reactor.

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.
