PERFLUOROSULFONATE-POLYETHER BASED SINGLE-ION CONDUCTORS

New salts with monomer functionality and bearing a perfluorosulfonate group have been synthesized. These salts contain one or two carbon dou ble bonds and thus can be incorporated into crosslinked solvating iono mers. Another family possesses epoxy rings and can be copolymerized wi th ethylene oxide. The results, in terms of ionic conductivities and t hermal behavior are reported for these single-cation conductor polymer electrolytes. The conductivity values of these materials are markedly higher than those previously reported for other t(+) = 1 materials. T he loss in conductivity, as compared to the untethered salt complexes, corresponds approximately to that attributed to the anionic conductiv ity. Alkali metals rank in the order sigma(K)- > sigma(Na)- > sigma(Li +).
