The mechanism of formation of lithium nickel oxide phases by solid state reaction of Ni and Li2CO3in the temperature range 700-800°C was investigated. Cubic LixNi1-xO solid solution with nominal composition x = 0.30 was obtained throug the formation of hexagonal LixNi1-xO. However, hexagonal LixNi1-xO with x = 0.44 arose from cubic LixNi1-xO. To explain this behaviour, the existence of an equilibrium relationship between cubic disordered and hexagonal ordered LixNi1-xO phases is proposed.
