Double Carbon Coating of LiFePO4 as High Rate Electrode for Rechargeable Lithium Batteries

Micrometer-size LiFePO4 spheres with homogeneous double carbon coating layers have been prepared as potential electrode materials for battery applications. The double carbon-coated LiFePO4 electrodes in a lithium-ion cell exhibited discharge capacities of the order of 160 mAh g(-1) and 115 mAh g(-1) at 25 degrees C under 0.1 C-rate and 10 C-rate, respectively.
