摘要	LiFePO4/C cathode materials were synthesized by carbothermal reduction method, using Fe2O3, LiH2PO4 as starting materials, glueose as carbon source. The effect of the amount of lithium in reactant on the electrochemical properties of LiFePO4/C cathode materials was investigated. The structure, morphology and electrochemical properties of LiFePO4/C were analyzed by XRD, SEM and galvanostatic charge-discharge method and cyclic voltammetry (CV), respectively. The results indicate that when excess additional amount of lithium element is 10% of theoretical value, the sample has optimal electrochemical properties and exhibits a initial discharge capacity of 156.3 and 137.5 mAh/g at 0.2 and 1 C (1 C=170 mA/g) rates, respectively, there is no significant capacity fade after 20 cycles.
