TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The hydrocarbon radical is a radical having a 6-30C chain optionally substituted by ether oxygen(s), or is a radical formed from poly(ethylene oxide) of molecular weight 100-2000 Dalton. It can be derived from dodecane. The olefinically unsaturated fluorocarbon is in the form of sulfonate, imide or methide.The electrolyte liquid comprises dimethyl carbonate, diethyl carbonate, ethyl methyl carbonate, propylene carbonate, ethylene carbonate, methyl acetate, ethyl acetate, methyl formate, methyl propionate, ethyl propionate, gamma-butyrolactone and/or dimethyl succinate.    TECHNOLOGY FOCUS - POLYMERS - Preferred Polymer: The electrolyte polymer is polyether, polyether(meth)acrylate, comb-shaped polyether, polyvinyl ether and/or poly(bis-(methoxyexothyethoxide)phosphazene), preferably polyethylene oxide or poly(polyethylene glycol) methyl ether acrylate. The separator is an ionomer or a copolymer of polyvinylidene fluoride and hexafluoropropylene or an aliphatic polyether or a polyether acrylate. Preferred Definitions:    Z = F or H (preferably F);    a, b = 1;    c = 0 or 1;    X = F.    When Z is H, a = 0.    EXAMPLE - Perfluoro(3,6-dioxa-4-methyl-7-octenesulfonyl fluoride)-grafted dodecane (25.7 g), and anhydrous tetrahydrofuran (150 ml) were charged to a flask. After all grafted dodecane dissolved, lithium hydride (1 g) was added. The reaction mixture was cooled to 0degreesC and a solution of malononitrile (4.15 g) in tetrahydrofuran (50 ml) was added for 2 hours. After addition, the mixture was allowed to warm to room temperature. Methanol (20 ml) was added and the solvent was removed. The viscous yellowish liquid was further processed to obtain yellowish amorphous solid (9 g).    Solutions of this compound in propylene carbonate showed conductivities: 0.125 M: 1.03 mS/cm, 0.25 M: 1.41 mS/cm, 0.5 M: 1.37 mS/cm. A 1.0 M solution in a 2:1 solution of ethylene carbonate and dimethyl carbonate gave 1.3 mS/cm. An electrolyte solution containing the composition was used in the assembly of a coin cell. The cell showed a cycle life of 165 cycles.
