Process for making an electrode active material

Abstract

Disclosed herein is a process for making an electrode active material, where said process includes the following steps: (a) providing an (oxy)hydroxide or oxide of TM, where TM is a combination of metals, and where TM contains Ni and at least one of Mn and Co; (b) treating said oxide or (oxy)hydroxide from step (a) with a non-aqueous or aqueous solution of a compound of M2, where M2 is selected from the group consisting of Ti, Zr, Nb, and Ta; (c) removing the solvent(s), thereby obtaining a solid residue; (d) mixing the solid residue from step (c) with a source of lithium and, optionally, at least one compound of Ti or Al or Zr; and (e) treating the mixture obtained from step (d) thermally at a temperature in the range of from 550 to 900° C.
