Abstract: Disclosed herein is a process for making a particulate (oxy)hydroxide of TM including the steps of:
(a) providing an aqueous solution (α) containing a water-soluble salt of nickel, one metal selected from cobalt and manganese, a compound of at least one metal selected from Ti, Zr, Mg and Nb, an α- or β-hydroxy carboxylic acid or ascorbic acid or of an amino acid selected from glycine, alanine and serine, or their alkali metal salts, an aqueous solution (β) containing an alkali metal hydroxide and, optionally, an aqueous solution (γ) containing ammonia,
(b) combining the solution (α), the solution (β), and, if applicable, the solution (γ) at a pH value between 11.0 and 13.0 in a stirred tank reactor, thereby creating solid particles of a hydroxide containing nickel, said solid particles being slurried.-

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.
