Synthesis and thermal decomposition kinetics of LiNiO2

A layered LiNiO2 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 LiNiO2 show that it has a reversible capacity of more than 168mA*h*g-1. It was found that with increasing temperature, LiNiO2 decomposed in air followed with three reaction stages, the apparent activation energies were 747.18±1.0kJ*mol-1, 932.46±1.0kJ*mol-1 and 1126.97±1.0kJ*mol-1 respectively, and the kinetic equations of the three reaction stages were obtained.
