Cycling Performance of LiFePO4 as the Cathode Materials for Lithium Polymer Batteries
The cycle behavior and rate performance of C-LiFePO4/SPE/Li cell have been investigated at 25 °C. Carbon coated LiFePO4 (C-LiFePO4) was employed as cathode and 25PVDFLiClO4EC10PC10 was used as solid polymer electrolyte (SPE). The C-LiFePO4/SPE/Li cell exhibited above 140 mAh/g of discharge capacity at 0.1 mA/cm2 and excellent reversible cyclability with a stable capacity on cycling. In addition, the discharge capacity of C-LiFePO4/SPE/Li cell was 150 mAh/g at 0.1 C (0.02 mA/cm2) and 130 mAh/g at 1 C (0.2 mA/cm2), respectively.
