چکیده انگلیسی
LiFePO4/carbon composite electrode was prepared and applied to the dry polymer electrolyte. Enhanced low-temperature performance of LiFePO4 was achieved by modifying the interface between LiFePO4 and polymer electrolyte. The molecular weight of the polymer and the salt concentration as the Li/O ratio were optimized at 3 × 105 and 1/10, respectively. Impedance analysis revealed that a small resistive component occurred in the frequency range of the charge transfer process. The reversible capacity of the laminate cell was 140 mAh g−1 (C/20) and 110 mAh g−1 (C/2) at 40 °C, which is comparable to the performance in the liquid electrolyte system.
