TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compositions: The ionomer contains up to 150 (preferably 5-90) short chain branches per 1000 methylene groups in the backbone. The composition is mixed with 50 % by weight of silica particles having an average particle size of less than 1 microns. The concentration of ionic radicals is 1-20 mol % (preferably 2-10 mol %). The ionically conductive ionomer also consist of an electrically microporous insulating polymer film or sheet which the gel is imbibed within the micropores. Preferred Preparation: The ionomer is mixed with at least one electrode active material and imbibed by an aprotic solvent from organic carbonates or their mixtures. Preferred Electrode: The electrode is a carbon black having a ratio of 0.05:0.8 (preferably 0.01:0.2) with the ionomer. Preferred Solvent: The solvent is a mixture of ethylene carbonates and at least one from dimethyl carbonate, methyl ethyl carbonate or diethyl carbonate. But it is especially water or methanol. Preferred Product: The ionomer is in the form of film, sheet or gel.    TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Electrochemical Cell: The electrochemical cell comprises anodes and cathodes with a separator in-between, and a connector to the outside source. Preferred Definitions:    X = O;    a = 0;    Rf = -O-((CFRf'CF2)x-Oy)m-;    Rf' = perfluoroalkyl or fluorine (preferably fluorine);    x = 0-3 (preferably 1 or 2);    y = 0 or 1 (preferably 0);    m = 0-3 (preferably 1 or 2);    Rn = -(CH2)z- (preferably (CH2)4, Rf(CF2)x);    z = 2-6 (preferably 4);    R = ethyl, propyl, or butyl;    M+ = alkali metal cation (preferably lithium cation)    EXAMPLE - 0.2 g dried ionomer was placed in a sealed flask with 7 g tetrahydrofuran (THF), stirred for 2 hours at 400 rpm and 70degreesC. 0.5 g carbon black was added while stirring for 15 minutes. The slurry were cast on to silanized Mylar and allowed the THF to evaporate. A 12 mm diameter of a positive electrode was punched from the graphite film and dried under vacuum at 100degreesC, giving a mass of 11.6 mg having a thickness of 160 microns. A separator (11.5 mg, 43 microns) was punched from the separator film from above. The material was soaked in excess anhydrous EC/DMC for 10 minutes, absorbing 21.8 mg of liquid. They were assembled with a lithium foil negative electrode into a size 2325 coin cell. The cell was discharged at a constant current of 0.5 mA and 0.01 V with a capacity of 2.42 mAh on its discharged. The cell was charged at 0.5 mA, 1.2 V whose capacity was 1.97 mAh, indicating 81% efficiency in the first discharge/charge cycle.
