中文摘要：
应用固相反应法在惰性气氛下合成橄榄石型LiFePO4,然后制成聚苯胺掺杂C-LiFePO4复合正极材料.XRD,交流阻抗及电化学方法等测试表明,聚苯胺掺杂对LiFePO4电化学性能有一定的改善.当放电倍率为0.1C时,掺杂10%聚苯胺的（C-LiFePO4）0.9（PANI）0.1样品的放电容量达到164 mAh.g^-1,且循环稳定性良好.在0.5C和1C的放电倍率下,也可以分别达到121.6 mAh.g^-1和110.1 mAh.g^-1的放电比容量.
英文摘要：
The olivine LiFePO4 cathode materials were synthesized using the solid state method in an inert atmosphere by doping polyaniline into the C-LiFePO4. It was found that the electrochemical performance of polyaniline-doped C-LiFePO4 slightly improved. At a low discharging rate （0.1 C）, the capability of （C-LiFePO4）0.9 （PANI）0.1 reached 164 mAh · g^-1 When the charge-discharge rate is increased to 0.5C and 1.0C, the showed capacities of 121.6 mAh · g-1 and 110.1 mAh · g^-1 were obtained, respectively.
