Influence of Ni/Co Ratio for LiCoxNi1-xO2 on Electrochemical Performance

    Graphical Abstract
    • Abstract
  • A series of LiNi1-xCoxO2 (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 LiNi0.8C0.2O2 has the best electrochemical performance, delivering specific capacities of 170-180 mAh/g and good over-charge resistance compared with LiNiO2.
