ABSTRACT:
An electrolyte composition that includes a salt disposed in a matrix in which the salt has a formula selected from the group consisting of ##STR1## in which X.sup.- is --O.sup.-, --N.sup.- SO.sub.2 R.sub.f.sup.3, or ##STR2## Z is --CF.sub.2 --, --O--, --NR.sub.f.sup.8 --, or --SF.sub.4 --; R.sub.f.sup.1 and R.sub.f.sup.2, independently, are --CF.sub.3, --C.sub.m F.sub.2m+1, or --(CF.sub.2).sub.q --SO.sub.2 --X.sup.- M.sup.+ ; R.sub.f.sup.3, R.sub.f.sup.4, and R.sub.f.sup.5, independently, are --CF.sub.3, --C.sub.mf.sub.2m+1, --(CF.sub.2).sub.q --X.sup.- M.sup.+, ##STR3## R.sub.f.sup.8 is --CF.sub.3, --C.sub.m F.sub.2m+1, or --(CF.sub.2).sub.q --SO.sub.2 --X.sup.- M.sup.+ ; R.sub.f.sup.6 and R.sub.f.sup.7, independently, are perfluoroalkylene moieties having the formula --C.sub.r F.sub.2r ; n is 1-4; r is 1-4; m is 1-12; q is 1-4; and M.sup.+ is a counterion.
