Abstract

Disclosed herein is a process for the manufacture of a coated cathode active material comprising the steps of:

(a) providing a particulate electrode active material according to general formula Li1+xTM1−xO2, where TM is a combination of metals including Ni and Mn, and, optionally, at least one element selected from Al, Mg, or transition metals other than Ni and Mn, and x is in the range of from zero to 0.2, where at least 50 mole-% of the metal of TM is Mn,(b) treating the particulate electrode active material with an aqueous solution of at least one salt of Sn2+,(c) removing the water, thereby obtaining a solid residue, and(d) treating the residue obtained from step (c) thermally.
