摘要：

Polymer gel electrolyte with addition of fumed silica was prepared by the UV polymerization of methyl methacrylate, oligomer of ethyl glycol dimethacrylate and liquid electrolyte. The effect of fumed silica on the interfacial stability of lithium electrode and polymer gel electrolyte membrane was studied by environmental scanning electron microscopy (ESEM), FTIR and electrochemical AC impedance. The addition of fumed silica has an effect on morphology of polymer gel electrolyte membrane. The silica is interactive with solvent and polymer matrix and it can trap impurities in the polymer gel electrolyte. All of them are beneficial to the interfacial stability, which is confirmed in the AC impedance spectrum. (C) 2002 Published by Elsevier Science B.V.
