Abstract

The polyphosphazene, poly[bis(2-2-methoxyethoxy) ethoxy]phosphazene (I), shows excellent promise as a solid electrolyte host when LiCF3SO3 is used as the charge carrier. The ionic conductivity of the gamma irradiated crosslinked polymer/salt complexes was investigated through two complementary sets of polymer-electrolyte combinations. In one (series A) the salt was added to the polymer before irradiation, while in the second (series B) the salt was added to a solvent-swelled polymer after irradiation. These experiments were carried out to eliminate the possibility that the presence of LiCF3SO3 during irradiation would affect the ionic conductivity of the final product. Series A and B each consisted of six thin films of I with 0.25 equivalent of LiCF3SO3 per polymer repeat unit.
