In present paper, composite polymer electrolyte (CPEs), which are composed of poly(ethylene oxide)-poly(methyl methacrylate) (PEO-PMMA) matrix, lithium perchlorate (LiClO4) as a salt, nano-sized TiO2 as the inorganic filler were prepared in order to study the influence of TiO2 content on the electrochemical characterization of the composites. The effect of addition of TiO2 on the properties of the CPEs is evaluated by DSC, XRD, SEM, AC impedance and cyclic voltammetry(CV). It is found that the ionic conductivity of the CPE is significantly improved by addition of TiO2. The enhanced ionic conductivity was dependent on the decreased crystallinity and the changed morphologies. |
