Characterization of Li1-xNi1+xO2 prepared by using tartaric acid as a complexing agent

Li1-xNi1+xO2 powder was prepared by using tartaric acid as a complexing agent. A 1 : 1: 2 mole ratio of Li : Ni : tartaric acid was used to form carboxylate precursors which were calcined at 650-800°C for 14-48 h. TGA of the precursors showed that formation of Li1-xNi1+xO2 initiates at 600°C and abo...
