Abstract
- Composite gel polymer electrolytes (CGPE) were prepared using 1,3 Dioxolane (DIOX)/Tetraethyleneglycol dimethylether (TEGDME) as a combination of plasticizers, comprising with PEO, lithium salt (LiClO<subscript>4</subscript>) with the addition of filler SiO<subscript>2.</subscript> The composite gel polymer electrolytes were prepared by simple solution casting technique in an argon atmosphere. The electrolyte films were subjected to thermal, structural, morphological and electrochemical ac impedance analysis. A Lithium symmetric cell (Li/CGPE/Li) was fabricated and interfacial resistance as a function of time was studied. The film was thermally stable up to 298 °C. The ionic conductivity of high conducting sample is obtained in the order of 10<superscript>−4</superscript> at ambient temperature. The transport properties of the gel polymer electrolyte were measured and the values are 0.6 which is sufficient for battery applications. The stability of the electrolyte film was analysed using the linear sweep voltammetry technique and the film was stable up to 3.4 V. [ABSTRACT FROM AUTHOR]
