摘要	LiFePO4/C and LiFePO4/C+Ag samples were prepared by sol-gel method. Samples were characterized by XRD, SEM, EIS and electrochemical discharge and charge tests. Silver modification does not affect the olivine structure of LiFePO4, but enhances its electrochemical performance in terms of discharge capacity and rate capacity. Discharge capacities are improved from 130.8 mAhg(-1) of LiFePO4/C to 149.8mAhg(-1) of LiFePO4/C+Ag cathodes. EIS measurements show that Silver modification slightly decreases the charge transfer resistance of LiFePO4/C, and lithium ion diffusion coefficient is enhanced from 2.89 x 10(-14) to 8.17 x 10-(13) m(2) s(-1).
