The LiFePO₄/C composites have been successfully synthesized by adopted Li₂CO₃ and LiOH·H₂O as mixed lithium source, the carbon content of the as-prepared LiFePO₄/C materials have been optimized. Since the melting point of LiOH is lower than that of Li₂CO₃, adopt mixed lithium source can achieve better melting state at the same temperature, and favors the conductivity of lithium ions during the high temperature synthetic process to obtain pure LiFePO₄ structure. The carbon content of LiFePO₄/C composites were optimized to improve the electroconductivity and control the particle size. The LiFePO₄/C cathode displayed excellent crystal structure, processability and electrochemical performances. The discharge capacity of the as-obtained LiFePO₄/C composites is as high as 158.2 mAh·g^-1, after 100 days storage, the capacity retention of full cells is still maintained higher than 94.0%, representing the superior long-term reliability of the optimized LiFePO₄/C material.
