Abstract: Disclosed herein is a process for the manufacture of coated cathode active materials including the steps of: (a) providing a particulate electrode active material based on a lithiated oxide according to general formula Li1+xTM1−xO2 and x is in the range of from zero to 0.2, (b) treating said particulate electrode active material with water, and subsequently removing the majority of the water by a solid-liquid separation method, thereby obtaining a solid residue, (c) treating the solid residue material from step (b) with a source of boron and with at least one compound of Mg, Ca, Sr, Ba, and Zn selected from the respective sulfates, oxides, and hydroxides, thereby obtaining an intermediate, and (d) treating the intermediate obtained from step (c) thermally.

Abstract: Described herein is a process for making an electrode active material according to general formula Li1+(TM1-yM1y)1-xO2, where TM includes a combination of Ni and at least one of Co, Mn and Al, M1 is selected from the group consisting of Nb, Ta, and at least one of Co, Mn and Al, y is in a range of from 0.001 to less than 0.01, and x is in a range of from zero to 0.2, said process including the following steps:



(a) mixing

(A) a mixed oxide or (oxy)hydroxide of Mn, Co and Ni, and
(B) at least one lithium compound selected from the group consisting of lithium hydroxide, lithium oxide and lithium carbonate, and
(C) an amorphous compound of Nb or Ta, and


(b) subjecting said mixture to heat treatment,
where at least 60 mole-% of a transition metal of TM is Ni.
