TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Composition: The electrolytic composition comprises aprotic polar solvents; a conductive salt (greater than 0.5, preferably 0.5-2 moles/L); and perfluoropolyether additive (higher than 10, preferably 10-500 meq/L). The ionic species are at least partially dissolved or dispersed in a matrix material.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Materials: The conductive salt cation is alkaline, alkaline-earth metal, trivalent metal, or tetraalkylammonium. The anion is hexafluorophosphate (PF6-), perchlorate (ClO4-), hexafluoroarsenate (AsF6-), tetrafluoroborate (BF4-), (Rf1SO2)(Rf2SO2)N-, or RfvSO3-Rf1, Rf2, Rfv = 1-4C perfluoroalkyl optionally containing heteroatoms.The aprotic polar solvents are 1,2-dimethoxyethane, 1,2-diethoxyethane, 1,3-dioxolane, 2-methyl-1,3-dioxalane, 4-methyl-1,3-dioxalane, tetrahydrofuran, 2-methyltetrahydrofuran, 1,4-dioxane, N,N-dimethylformamide, dimethylsulfoxide, or preferably ester carbonates. The ester carbonate is dimethylcarbonate, diethylcarbonate, propylenecarbonate, or ethylenecarbonate.    TECHNOLOGY FOCUS - POLYMERS - Preferred Materials: The matrix material is in the form of solid, liquid polymer, gel or porous membrane. The solid polymer is polyethylene oxide, polyester, polyacrylate, polyvinylidenefluoride, or polyacrylonitrile. The porous solid membrane is polyethylene or polypropylene having a surface tension of 28-35 mN/m. The perfluoropolyether additive is obtained by conversion of the fluorosulfonyl groups -SO2F into -SO3M groups carried out on the homopolymers of the monomer CF2=CFOCF2CF2SO2F or on the copolymers of the monomer with perfluoro olefins (tetrafluoroethylene and/or perfluoropropene). EXAMPLE - A perfluoropolyether-lithium sulfonate was dissolved in 1 N concentration in a mixture of ethylenecarbonate/propylenecarbonate (50/50 by weight). A low density polyethylene plate was dipped into the prepared solution. The advancing dynamic contact angle and the recession angle were both less than 5 degrees during the fourth cycle. The surface tension value was 21 mN/m. An imide salt solution in ethylene-carbonate/propylene-carbonate gave a surface tension value of 31 mN/m. The advancing dynamic contact angle and the recession angle during the fourth cycle were 67 and 25, respectively.
