Provided is a non-aqueous electrolyte containing a non-aqueous electrosolvent and a lithium salt, wherein the non-aqueous solvent includes a carbonate solvent, the lithium salt contains a fluorine-containing cyclic sulfonylimide salt represented by general formula (1): (in the formula, R.sup.f each may be the same or different and each represent a fluorine atom or a C4 or lower perfluoro group), and a fluorine-containing sulfonamide compound represented by general formula (2): H(CR.sub.2).sub.mSO.sub.2NHM.sup.2 (in the formula, R each may be the same or different and each are a fluorine atom or a trifluoromethyl group, M.sup.2 is Li, Na, K, H, or NH.sub.4, and m is 1 or 2) is contained in an amount of 1,000 mass ppm or less relative to the total amount of non-aqueous electrolyte.

The invention relates to a novel synthesis method for forming superacid functional molecules that include monomers, as well as new polymers and copolymers formed from the monomers, and uses for these superacid molecules, polymers, and copolymers. The superacid molecules have an alpha, alpha-difluorosulfonic acid functionality that can be obtained by a reaction between various Grignard reagents and an alkyl(2-fluorosulfonyl)-1,1-difluoroacetate, such as methyl (2-fluorosulfonyl-1,1-difluoroacetate. The molecules, polymers and copolymers would be expected to have enhanced ion conductivity, and would be useful in a variety of applications, including as ion-conductive materials, surfactants, and ion exchange resins.
