Polymer electrolytes prepared from poly (ethylene oxide) and lithium hexafluoarsenate with varying compositions of dibutyl sebacate and ethylene carbonate were studied by X-ray diffraction and A.C.impedance methods. Electrolyte composition (PEO)8-LiAsF6-(DBS)0.4-(EC)0.1 has been arrived as an optimum composition as evident from its freestanding ability with reasonably high conductivity. The temperature dependence of the complex electrolytes obeys the Arrehenius law. The activation energy for the film with the platicized polymer electrolyte 0.81 KJ/mol, is considerably lower than the value 10 KJ/mol obtained for the unplasticized electrolyte
