LiFePO4/C composite was synthesized by high temperature solid2state reaction using iron (Ⅱ) oxalate, ammonium di2hydrogen phosphate and lithium carbonate with a kind of carbohydrate dissolved in the dispersant (eth-anol) as carbon sources added to the synthetic precursor. The samples were characterized by X2ray diff raction (XRD), scanning elect ron microscopy observations (SEM), charge/ discharge test, cyclic voltammet ry(CV) and carbon analysis. The result s show that the synthesis of LiFePO4/C has ordered olivine st ructure. The carbon has two advantages: optimizing particle size of LiFePO4 and increasing the elect ronic conductivity and high Li+diffusivity. The cathode material can demonst rate a charge/discharge flat voltage of 3.4V (vs Li+/Li). Especially the active material with 15% and 20% carbohydrate added according to the final product of lithium iron phosphate shows very good elect rochemical performance delivering about initial 150.2 mA·h·g-1 and 162.0 mA·h·g-1 specific capacity respectively at 0.1 C rate and the carbon contents in the final production are only 5.17% and 5.29%, respectively.
