    Abstract: Process for making a particulate (oxy)hydroxide of TM wherein TM represents a combination of metals, and wherein TM comprises nickel and at least one metal selected from cobalt and aluminum and manganese, wherein said process comprises the steps of: (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, wherein said second reaction vessel contains a slurry of a hydroxide of TM, wherein the pH value in step (b) is higher than in step (a) and the temperature is in the range of from 45° to 80°C, thereby forming and growing particles of hydroxide of TM, (c) removing the particles from step (b) from the liquid by a solid-liquid separation method, and drying the particles, (d) returning liquid phase obtained in step (c) to the first reaction vessel.
