ABSTRACT:
A single-ion electrolyte achieves conductivity greater than 10.sup.-3 S/cm at 20.degree. C. by employing repeating mer units which are functionalized by fluoroalkylsulfonate groups. Preferred backbones for the electrolyte include polysiloxanes, polymethacrylates and poly(alkylene oxides). More preferred backbones have the structure ##STR1## wherein A is selected from the group consisting of C and Si such that when A is C then R.sup.4 is (CH.sub.2).sub.1-100' and when A is Si then R.sup.4 is O; R.sup.1 and R.sup.2 are independently selected from the group consisting of hydrogen, lower alkyl, lower alkoxy, fluorinated lower alkyl, fluorinated lower alkoxy, and fluoroalkylsulfonate; and R.sup.3 is null or selected from the group consisting of O, (O).sub.1-100, O--CH.sub.2, (O).sub.1-100 --(CH.sub.2).sub.1-100.
