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 an electrode active material, where said process includes the following steps:
(a) Providing a hydroxide TM(OH)2 or an oxyhydroxide of TM, where TM is one or more metals and contains Mn, optionally, Co, and from 85 to 95 mol % Ni, referring to the sum of Ni, Co and Mn;
(b) Drying said hydroxide TM(OH)2 or oxyhydroxide of TM at a temperature in the range of from 400 to 600° C., thereby obtaining an oxide or oxyhydroxide of TM with a residual moisture content of from 200 to 500 ppm;
(c) Mixing said oxide or oxyhydroxide from step (b) with a source of lithium, at least one compound of Mg or Al, and at least one compound of Ti or Zr; and
(d) Treating the mixture obtained from step (c) thermally at a temperature in the range of 550 to 875° C.-

Abstract: Described herein is a process for making a particulate (oxy)hydroxide of TM, where TM are metals and TM includes at least 60 mol-% nickel, and where said process includes the steps of:
(a) providing an aqueous solution (α) including water-soluble salts of Ni and of at least one metal selected from the group consisting of Co and Mn, and, optionally, at least one further metal selected from the group consisting of Ti, Zr, Mo, W, Al, Mg, Nb, and Ta, and an aqueous solution (β) an alkali metal hydroxide and, optionally, an aqueous solution (γ) including ammonia,
(b) combining the solution (α) and the solution (β) and, if applicable, the solution (γ) at a pH value in a range of from 11.0 to 13.0 in a stirred tank reactor, thereby creating solid particles of a hydroxide containing nickel, said solid particles being slurried.
