Abstract: Disclosed herein is a process for the manufacture of a cathode active material with a coreshell structure. The process includes the steps of: (a) providing a particulate electrode active material according to a general formula Li1+xTM1−xO2, where TM is a combination of metals and includes Ni and Mn, and, optionally, at least one element selected from Al, Mg, Ba and transition metals other than Ni and Mn, and x is in the range of from 0.075 to 0.2, where at least 50 mole-% of the metal of TM is Mn, (b) treating the particulate electrode active material with an aqueous buffer solution with a pH value in the range of from 2.0 to 10.5, (c) removing the liquid phase by a solid-liquid separation method, and (d) treating the residue from step (c) at a temperature in the range of from 180 to 750° C.

Abstract: Disclosed herein is a process for making a particulate (oxy)hydroxide of TM, where TM represents a combination of metals and includes nickel and at least one metal selected from cobalt and aluminum and manganese. The process includes: (a) combining an aqueous slurry of metallic nickel and at least one metal selected from aluminum and transition metals other than nickel with an oxidant selected from oxygen and nitrate in a first reaction vessel or in a first group of reaction vessels at a temperature of from 5° to 40° C., (b) transferring aqueous reaction medium from the first reaction vessel to a second reaction vessel, where the second reaction vessel contains a slurry of a hydroxide of TM, (c) removing the particles from step (b) from the liquid by a solid-liquid separation method, and drying the particles, and (d) returning liquid phase obtained in step (c) to the first reaction vessel.
