A layered LiNiO 2 with high crystallinity was synthesized by sintering the finely prepared mixture of lithium hydroxide and nickel hydroxide in the oxygen atmosphere. The electro chemical properties of LiNiO 2 show that it has a reversible capacity of more than 168?mA·h·g -1 . It was found that with increasing temperature, LiNiO 2 decomposed in air followed with three reaction stages, the apparent activation energies were 747.18± 1.0?kJ·mol -1 , 932.46± 1.0?kJ·mol -1 and 1?126.97± 1.0?kJ·mol -1 respectively, and the kinetic equations of the three reaction stages were obtained.
