Li1-xTixFePO4(0≤x≤0.02)制备表征及电化学性能研究

Abstract

Abstract: The Li site doped cathod material Li_1-xTi_xFePO₄ (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 Li_1-xTi_xFePO₄ had better capacity and rate performance than those of LiFePO₄/C.

Key words: LiFePO₄, olivine, discharge capacity
