摘要

Electrolyte compsns. (III) comprise a matrix contg. a salt of formula (Rf1)(Rf2)N(CF2)nSO2X-M+ (I) or Z(Rf1)(Rf2)N(CF2)nSO2X-M+ (II); X- = O-, -H-SO2Rf3 or (Ff5SO2)-C--(SO2Rf4); Z = CF2, O, NRf8 or SF4; Rf1 and Rf2 = -CF3, -CmF2m+1 or -(CF2)q-SO2-X-M+; m = 1-12; n, r and q = 1-4; Rf3, Rf4 and Rf5 = any Rf1, (i) or (ii); Rf6 and Rf7 = perfluoroalkylene of formula CrF2r; Rf8 = any Rf1; M+ = a counter ion.
