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.
A process for making a particulate (oxy)hydroxide of TM, wherein TM are metals and TM comprises at least 60 mol-% nickel, and wherein said process comprises the steps of:
A particulate (oxy)hydroxide of TM, wherein TM comprises at least 70 mol-% nickel, wherein said (oxy)hydroxide has an average secondary particle diameter (D50) in a range of from 2 to 20 μm, wherein TM includes 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, wherein said (oxy)hydroxide comprises in a range of from 0.05% to 1% by weight C as organic carbon, and wherein at least 60 vol.-% of the secondary particles comprise agglomerated primary particles that are perfectly radially oriented primary articles and primary particles whose deviation to a perfectly radial orientation is at most 5 degrees.
