中文摘要：
以介孔分子筛SBA-15为造孔剂和填料，研究出一种无需使用增塑剂制备复合微孔型聚合物电解质（SBA-15 CMPE）的新方法．组装Li／SBA-15 CMPE／Li对称电池，并利用电化学阻抗谱（EIS）技术研究了存放时间、循环伏安（CV）扫描、恒电流极化以及环境温度等对Li／SBA-15 CMPE界面性质的影响．通过将成膜浆料直接浇铸在用水性粘合剂制备的中间相微球碳（MCMB）电极片上，制备附有SBA-15 CMPE的一体化电极（MCMB／SBA-15 CMPE）．用该MCMB／SBA-15 CMPE所组装的三电极模拟电池具有良好的循环性能，EIS研究揭示了其首次阴极极化过程中碳电极上SEI膜的形成、生长和稳定的过程．
英文摘要：
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.
