Abstract: Process for making an electrode active material according to general formula Li1+xTM1−xO2, wherein TM is a combination of Mn, Co and Ni, optionally in combination with at least one more metal selected from Al, Ti, and W, wherein at least 50 mole-% of TM is Ni, and x is in the range of from zero to 0.2, said process comprising the following steps: (a) mixing (A) a mixed oxide or oxyhydroxide or hydroxide of TM, and (B) at least one lithium compound selected from lithium hydroxide, lithium oxide and lithium carbonate, and so that the molar ratio of Li to TM is in the range of from 0.70 to 0.97. (b) Subjecting said mixture to heat treatment at a temperature in the range of from 300 to 900° C., (c) Mixing with at least one lithium compound (B), so that the total molar ratio of Li to TM is in the range of from 1.0 to 1.1, (d) Subjecting said mixture to heat treatment at a temperature in the range of from 700 to 1000° C.
