TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Cation: The cation in the surfactant salt is lithium, sodium, calcium, barium, aluminum, europium, samarium, tetraethylammonium cation, tetramethylammonium cation, N-butyl pyridinium cation, or N-ethyl-N'-methyl-imidazolidinium cation. Preferred Conductive salt: The conductive salt comprises (CF3SO2)3C- anion, and anion of formula RfVSO3-, where RfV is 2-4C perfluoroalkyl.Preferred Amount: The molar ratio of conductive salt to surfactant salt in the electrolyte composition, is 99:1-90:10. The amount of the surfactant salt in the electrolyte composition is 10 weight percent (wt.%) or more based on the weight of the conductive salt.Preferred System: The electrochemical system comprises electrolyte composition comprising conductive salt and surfactant salt at a concentration of 0.5-1.5 mole/l and 10-100 mmol/l, respectively and a non-aqueous matrix material. The electrochemical system is a (rechargeable) battery, preferably a lithium battery. Preferred Definitions:    Rf0 = perfluoromethyl;    Rf = 4-12C perfluoroalkyl;    Rf' = 1-8C perfluoroalkyl;    M+n = alkali metal, alkaline earth metal, transition metal, rare earth metal, a group IIB metal, a group IIIB metal, tetraalkylammonium, N-alkylpyridinium or N,N'-dialkyl imidazolinum.    SPECIFIC COMPOUNDS - The conductive salt is lithium perfluoroethanesulfonate, lithium tris (perfluoromethanesulfonyl)methide, lithium bis(perfluoroethanesulfonyl)imide, lithium (perfluorobutanesulfonyl)(per-fluoromethanesulfonyl) imide, lithium, and/or perfluorobutane sulfonate, preferably lithium bis(perfluoromethanesulfonyl)imide. The surfactant salt is fluorinated imide salt chosen from (C8F17SO2)N-(SO2CF3) Li+, (C4F9SO2)2N-Li+, (C8F17SO2)2N-Li+, (C8F17SO2)N-Li+, (SO4C4F9)Li+, or ((CF3)2NCF2CF2SO2)2N-Li+.    EXAMPLE - A cathode comprising 44 g of lithium cobalt oxide (LiCoO2) with 5 g of conductive carbon VXC72 (RTM) and 1 g of polyvinylidene fluoride resin Kynar 461 (RTM), was manufactured. An anode comprising 21 g of XP3 petroleum coke, 1.2 g of Super S conductive carbon and 3 g of polyvinylidene fluoride, was manufactured. Battery separators made of polypropylene membrane and polyethylene membrane, were manufactured. A fluorinated imide surfactant salt ((C8F17SO2)N-(SO2CF3) Li+) at a 1 molar concentration was added to a 50/50 blend of propylene carbonate/ethylene carbonate to form a liquid electrolyte. The electrolyte was applied to the surface of the polyolefin separators. An electrochemical system comprising separators between cathode and anode, was manufactured. The contact angle initially and after 500 seconds of contact of electrolyte with the polyethylene separator were measured and were found to be 47 and 0. The liquid electrolytes comprising imide salts with perflourinated chains, has excellent wetting performance after contact for 500 seconds.
