摘要：
Li2.6Co0.4N anode material was prepared by solid-state reaction. The material was used to prepare Li2.6Co0.4N/natural graphite composite anode materials with the aim to improve the electrochemical performance of natural graphite. Natural graphite showed a low initial columbic efficiency of 69%, which was improved to -100% by adding 20 wt.% of Li2.6Co0.4N into the material. On the other hand, the composite materials showed better capacity retention than both pure Li2.6Co0.4N and natural graphite. The material containing 20 wt.% of Li2.6Co0.4N exhibited a reversible discharge capacity of 243 mAh g(-1) after thirty cycles, as compared to a capacity of 212 mAh g(-1) for natural graphite.
