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.-
