TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The process further comprising separating the shaped article from the heat and/or pressure. The vessel is a continuous plasticating extruder. The shaped article is formed by casting a film or sheet by passing the plastically formable composition through an extrusion die. Preferably the shaped article is formed from the plastically formable composition by calendering, thermoforming, injection molding, or compression molding. The further comprising, the step of forming a layered structure comprising the shaped article.Preferred Components: The polymer comprises 4-12 mol.% of perfluoroalkenyl monomer units. X is 0, M+ is an alkali metal cation, preferably a lithium cation, a = 0 or 1, R = CF3, R' = F, and b = 1. The polymer further comprises up to 20 mol.% of monomer units selected from tetrafluoroethylene, trifluoroethylene, chlorotrifluoroethylene, vinyl fluoride, hexafluoro-propylene, perfluoromethyl vinyl ether, perfluoroethyl vinyl ether, ethylene, propylene, 1-octene, isobutylene, ethyl vinyl ether, acrylic acid and the alkyl esters, and methacrylic acid and the alkyl esters, and mixtures.Preferred Composition: The composition comprises a weight ratio of aprotic liquid to ionomer of 0.5 part aprotic liquid to 1 part of ionomer, to 12 parts aprotic liquid to 1 part ionomer, preferably the composition comprises a weight ratio of aprotic liquid to ionomer in the range of 4 parts of aprotic liquid to 1 part of ionorner, to 2 parts of aprotic liquid to 1 part of ionomer. The composition comprises 5-20 wt.% of the ionomer, 10-60 wt.% of the aprotic liquid, further comprising 45-80 wt.% of one or more electrode-active materials selected from carbon, metal oxides, lithium alloy-forming compounds, transition metal oxides, sulfur compounds, and electronically conductive polymers; and 1-12% of one or more conductive particles selected from carbon, metal, conductive metal oxides, and electronically conductive polymers. The aprotic liquid is selected from linear and cyclic carbonates, esters, diesters, lactones, amides, sulfoxides, sulfones, and ethers. The composition further comprises up to 50 wt.% on the total weight of ionomer plus aprotic liquid an inert filler selected from polyvinylidene fluoride homopolymer, polytetrafluoroethylene homopolymer, polyolefins, polyvinylidene fluoride-hexafluoropropylene copolymers, polyurethanes, polyalkylene oxides, polyacrylonitriles, polyfficthylacrylates, TiO2, SiO2, or Al2O3.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: The process further comprising up to 15 wt.% on the total weight of ionomer plus aprotic liquid of a mobile lithium salt selected from of LiPF6, LiPFxRfy, LiBF4, LiAsF6, LiClO4, LiSO3Rf, LiN(SO2Rf)(SO2Rf), LiC(SO2Rf)(SO2Rf)(SO2Rf) and mixtures, where f denotes partial or complete fluorination. The Rf groups are electron withdrawing, and may respectively be the same or different from one another.
