Abstract
Nanocomposite polymer electrolytes based on polyethylene glycol diacrylate and 1 M LiBF4 solution in γ-butyrolactone with addition of SiO2 nanoparticles were synthesized and studied. Resistance measurement at the Li/electrolyte and Li/nanocomposite electrolyte interface by the time-resolved electrochemical impedance showed its significant decrease in the presence of SiO2 nanoparticles. Charge-discharge cycling of prototypes of Li/LiFePO4 batteries for 50 cycles also showed the advantage of using nanocomposite polymer electrolytes over electrolytes without SiO2 additives.
