Abstract: Disclosed herein is a process for making a particulate (oxy)hydroxide of TM, where TM represents metals and includes nickel and at least one metal selected from cobalt and aluminum and manganese. The process includes the steps of:



(a) combining an aqueous slurry of metallic nickel and at least one metal selected from cobalt and manganese and aluminum with an oxidant selected from nitrate and peroxide in a reaction vessel under an atmosphere with less than 100 ppm O2, thereby obtaining an aqueous reaction medium with a pH value in the range of from 7.5 to 12 containing particles,
(b) removing the particles from step (a) from the liquid by a solid-liquid separation method, and drying the particles, and
(c) returning mother liquor obtained in step (b) to the reaction vessel.
