Abstract
Ionic conductivity of poly(vinylchloride) (PVC)/poly(methylmethacrylate) (PMMA) blended electrolytes containing LiCF3SO3 and LiBF4 has been studied using a.c. impedance spectroscopic technique. The variation of conductivity has been investigated as a function of polymer blend ratio, plasticizer content, ethylene carbonate (EC) and propylene carbonate (PC) and lithium salt concentration at 25, 40, 50 and 60°C. Electrolyte films showing conductivities in the 10−3 S cm−1 region have been obtained. A 7:3 PMMA/PVC blend electrolyte at 70% plasticizer content has been found to possess optimal properties in terms of conductivity and mechanical strength.
