Abstract
Layered LiNiO2 compounds are synthesized using a variety of conditions. Lithium hydroxide (LiOH·H2O) and nickel oxide (NiO) are used as precursors. Heat treatment at 750°C in oxygen is found to be an optimum synthesis condition. Excess lithium (Li:Ni=1not, vert, similar1.1 in molar ratio) is essential to produce LiNiO2 compounds with good electrochemical performance. According to DTA/TG analysis, the LiNiO2 can decompose to Li1−xNi1+xO2, which has a detrimental effect on the electrochemical reactivity of the LiNiO2 compound. The kinetic parameters of LiNiO2 electrodes are characterized by AC impedance spectroscopy.
