摘　　要：本文采用高温固相法合成锂离子电池正极材料LiNixCo1-xO2,主要探讨了x值及烧成温度对LiNixCo1-xO2的影响。通过XRD、SEM及电化学性能测试(恒流恒压充放电)等对其进行表征。结果表明:焙烧温度为760℃、x=0.8时制备的锂离子电池正极材料LiNi0.8Co0.2O2的结构和电化学性能最好。LiNixCo1-xO2 material as anode for lithium battery was synthesized by high-temperature solid reaction method. The effects of the value of x and the synthesis temperature were studied in emphases. The materials were characterized by XRD, SEM and electrochemical performance tests （constant current/constant voltage charge-discharge）. The results indicated that LiNixCo1-xO2 cathode material sintered under 760℃ showed better electrochemistry properties than others.
