Аннотация:Nanocomposite polymer electrolytes based on polyethylene glycol diacrylate and 1 M LiBF4solution in -butyrolactone with addition of SiO2 nanoparticles were synthesized and studied.Resistance measurement at the Li/electrolyte and Li/nanocomposite electrolyte interface bythe time-resolved electrochemical impedance showed its signifi cant decrease in the presenceof SiO2 nanoparticles. Charge-discharge cycling of prototypes of Li/LiFePO4 batteries for50 cycles also showed the advantage of using nanocomposite polymer electrolytes over electrolyteswithout SiO2 additives.
