Abstract

Lithium nickel oxide, used as the positive electrode in lithium batteries, crystallizes in the rhombohedral system (SG:R3¯ m) with a layered structure. In fact, stoichiometric has never been reported. The true formula is (0.00 < z < 0.20); z is dependent on the experimental conditions. This nonstoic...
