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.
