Abstract

Abstract

A series of LiNi_1-xCo_xO₂ (0<x< 1) were synthesized by solid state reaction. The effect of Co³⁺ substitution on Ni³⁺ content was investigated by XRD and electrochemical techniques. It is shown that LiNi_0.8C_0.2O₂ has the best electrochemical performance, delivering specific capacities of 170-180 mAh/g and good over-charge resistance compared with LiNiO₂.
