Abstract

Abstract

LiFePO₄ cathode materials were prepared by microwave processing with a domestic microwave oven. LiFePO₄/C composites were synthesized by carbon-coated to improve the capacity and rate capability. The microstructure and electrochemical performance of the composite were studied by X-ray diffraction, scanning electron microscopy and constant current charge-discharge experiment. The results indicated that the LiFePO₄/C composite with 4% carbon exhibited a higher reversible specific capacity of 109 mAh/g at 40 mA/g and an excellent rate capability.
