Abstract
Positive electrode material for a lithium battery comprises a lithiated metal layered oxide comprising metal elements arranged in layers of metal cations and lithium arranged in interlayers of lithium cations and, in part, in the layers of metal cations, the oxide has a stack arrangement 02 and corresponds to the formula (I): Li(a+b)NicMndCoeMfOg (I) wherein: *a represents the proportion of lithium in the interlayers, 0<a<1; *b represents the proportion of lithium in the layers of metal cations, 0<b<⅓; *c, d, e and f are between 0 and 1 and b+c+d+e+f=I; *1.9<g<2.1; *when f≠0, M is one or more of Al, Fe, Ti, Cr, V, Cu, Mg, Zn, Na, K, Ca, Sc; wherein the oxide is coated with an oxide of the formula (II): MnhM'iO2 (M) wherein: *0<h≤1.5, preferably h=1; *M′ is one or more of Ni, Al, Fe, Ti, Cr, V, Cu, Mg, Zn, Na, K, Ca, Sc; *0≤i≤1.5.
