The preparation of LiFePO4/C materials with particle size ranging from 10 π m to 100-200nm was attempted by controlled crystallization-carbothermal reaction, which has been experienced as an effective process for mass production of electrode materials. The structure, morphology and electrochemical performance of different materials were carefully characterized. With the decrease of particle size for LiFePO4 powders, the LiFePO4/C composite exhibit better capacity performance at high current density. This paves an effective way to synthesize size-controllable LiFePO4/C materials by mass production.
