PERFLUOROALKYSULFONATES, SULFONIMIDES, AND SULFONYL METHIDES, AND ELECTROLYTES CONTAINING THEM

摘要

An electrolyte composition that includes a salt disposed in a matrix in which the salt has a formula selected from the group consisting of in which X- is -O-, -N-SO2Rf3, or (Rf5SO2)-C--(SO2Rf4); Z is -CF2-, -O-, -NRf8-, or -SF4-; Rf1 and Rf2, independently, are -CF3, -CmF2m+1, or -(CF2)q-SO2-X-M+; Rf3, Rf4, and Rf5, independently, are -CF3, -CmF2m+1, -(CF2)q-SO2-X-M+, or Rf8 is - CF3, - CmF2m+1, or -(CF2)q-SO2-X-M+; Rf6 and Rf7, independently, are perfluoroalkylene moieties having the formula -CrF2r; n is 1-4; r is 1-4; m is 1-12; q is 1-4; and M+ is a counterion.
