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

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...

Zusammenfassung: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 °C under 0.1 C‐rate and 10 C‐rate, respectively.
