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.
