摘要： The present invention is directed towards a process for making a lithiated transition metal oxide, said process comprising the following steps:



(a) providing a precursor selected from mixed oxides, hydroxides, oxyhydroxides, and carbonates of nickel and at least one transition metal selected from manganese and cobalt, wherein at least 45 mole-% of the cations of the precursor are Ni cations,
(b) mixing said precursor with at least one lithium salt selected from LiOH, Li2O, Li2CO3, and LiNO3, thereby obtaining a mixture,
(c) adding at least one phosphorus compound of general formula (I)

XyH3-yPO4  (I)

wherein

X is selected from NH4 and Li,
y is 1 or 2,

to the mixture obtained in step (b),

wherein steps (b) and (c) may be performed consecutively or simultaneously,

(d) treating the mixture so obtained at a temperature in the range of from 650 to 950° C.
