Abstract: Described herein is a process for making a nickel composite hydroxide with a mean particle diameter d50 in the range from 3 to 20 μm including combining



(a) an aqueous solution of water-soluble salts of nickel and of at least one of cobalt and manganese, and, optionally, at least one of Al, Mg, B, or transition metals other than nickel, cobalt, and manganese,
(b) an aqueous solution of an alkali metal hydroxide and
(c) an aqueous solution of alkali metal (bi)carbonate or ammonium (bi)carbonate in the molar ratio of 0.001:1 to 0.04:1, and, optionally,
(d) an aqueous solution of alkali metal aluminate,

in a continuous stirred tank reactor or in a cascade of at least two continuous stirred tank reactors.
