Abstract: The Li site doped cathod material Li1-xTixFePO4 (0≤x≤0.02)and LiFePO4/C were prepared by  solid-phase method.Crystal structures,surface morphologies,capacity performance,and rate performance of the two samples were compared.Through the comparison,it was found that both the two kinds of sample had olivine structure,and the particle sizes of them were both at 2~4 μm.By the test of electrochemical performance,the Li1-xTixFePO4 had better capacity and rate performance than those of LiFePO4/C.

Key words: LiFePO4, olivine, discharge capacity
