Abstract
- The mechanism of formation of lithium nickel oxide phases by solid state reaction of Ni and Li 2 CO 3 in the temperature range 700–800 °C was investigated. Cubic Li x Ni 1 − x O solid solution with nominal composition x = 0.30 was obtained throug the formation of hexagonal Li x Ni 1 − x O. However, hexagonal Li x Ni 1 − x O with x = 0.44 arose from cubic Li x Ni 1 − x O. To explain this behaviour, the existence of an equilibrium relationship between cubic disordered and hexagonal ordered Li x Ni 1 − x O phases is proposed.
