Abstract
Olivine Li1-xMxFePO4(M=Cr3+、Mg2+、Mn2+、Ni2+)were synthesized by a polyacrylates-pyrolysis route.The structural and electrochemical properties of the as-synthesized cathode materials were investigated by powder X-ray diffraction(XRD),scanning electron microscopy(SEM),and electrochemical charge/discharge cycling.The results indicate that the metallic ions doped at low concentration do not affect the crystalline structure of the material,but considerably improve the rate capability and cycle performance of LiFePO4 at high rate.
