Abstract
The mechanism of formation of lithium nickel oxide phases by solid sta te reaction of Ni and Li2CO3 in the temperature range 700-800 degrees C was investigated. Cubic LixN1-xO solid solution with nominal composi tion x=0.30 was obtained throug the formation of hexagonal LixNi1-xO, However, hexagonal LixN1-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 LixN1-xO phases is prop osed.
