In this paper, a novel composite microporous polymer electrolyte that is made of poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) and mesoporous SBA-15 was prepared(designated as SBA-15 CMPE). Electrochemical impedance spectroscopy(EIS) was applied to investigate the effects of the storage time, cyclic voltammetry (CV) measurement, constant current polarization and ambient temperature on the Li/SBA-15 CMPE interface properties. The polymer film composite integrative electrode (designated as MCMB./SBA-15 CMPE) was prepared through a process that the membrane solution was cast directly on the mesocarbon microbead(MCMB) electrode with water-solubility bond. The result of CV shows that the model cell with three-electrode based on the MCMB/SBA-15 CMPE displayed a good,cyclical performance. The EIS result reveals the process of formation, growth and stabilization of. solid electrolyte interphase (SEI) film on MCMB/SBA-15 CMPE electrode during the first cathodic polarization.
