10 Claims

1. Process for making a lithiated transition metal oxide, said process comprising the following steps:

(a) providing a precursor selected from mixed oxides, mixed hydroxides, mixed oxyhydroxides, and mixed 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 a lithium salt and the lithium salt is Li₂CO₃, thereby obtaining a mixture,

X_yH_3-yPO₄ (I)

wherein:

X is selected from NH₄and 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.; and

wherein step (d) is performed in an atmosphere of oxygen or oxygen-enriched air.
