A method for producing a lithium transition metal oxide particle, wherein the following steps: (a) Ni, at least one transition metal selected from Co and Mn, and optionally Ti, Zr. , Mo, W, Al, Mg, Nb and a step of providing a particulate mixed transition metal precursor comprising at least one additional metal selected from Ta, (b) the precursor being at least one lithium compound. And a method comprising mixing with a process additive containing at least one potassium, (c) treating the mixture obtained in step (b) at a temperature in the range 700-1000 ° C.
