TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The cation species is alkalies, alkaline earths, lanthanides, yttrium, aluminum, or zinc. The anion species is hexafluorophosphide, chlorate, barium fluoride (BF4), CF3SO3, or arsenic hexafluoride. The first electrode member material is transition metal oxides, sulfides, phosphates, fluorides, alkali and alkaline earth metal-alloying metals and compounds, or open-structured carbonaceous materials. The cation species is lithium and the third electrode member material is lithiated transition metal oxide intercalation compound. The first electrode member material is lithium titanate (Li4Ti5O12). The second electrode member material is high surface area activated carbon powder. The dissociable salt is lithium hexafluorophosphide, lithium chlorate, LiN(CF3SO2)2, lithium perfluoroboride, LiCF3SO3, or lithium hexafluoroarsenide. The third electrode member material comprises lithium permanganate.    TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Component: The second electrode member material is pseudocapacitor, or double-layer capacitor electrode materials. The separator member comprises a microporous layer having a non-aqueous solution of the dissociable salt. Each member is bonded to contiguous members at its respective interface to form a unitary laminate structure. The electrode members are bonded to a respective electrically-conductive current collector (19) element.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The electrolyte comprises 0.5-2 M solution of at least one dissociable salt in an organic solvent from ethylene carbonate, diethyl carbonate, dimethoxyethane, sulfolane, and/or dipropyl carbonate. Preferred Composition: The electrolyte comprises 1 M solution of lithium hexafluorophosphide in 2:1 mixture of ethylene carbonate:dimethyl carbonate.    TECHNOLOGY FOCUS - POLYMERS - Preferred Material: The second electrode member material is foam, fiber, or fabric materials. The organic solvent can be dimethyl carbonate propylene carbonate diethoxyethane. The electrode members comprise a polymeric matrix with ion-intercalating and ion-adsorbing materials. The separator member layer comprises a polymeric membrane with pores or voids. EXAMPLE - A separator membrane (15) was cast from a composition comprising a solution of 6 g 88:12 poly(vinyl-idene fluoride-co-hexafluoropropylene) copolymer and 10 c compatible organizer plasticizer, propylene carbonate in 40 g acetone. An additional 4g powdered fumed silica was dispersed in the solution. The composition was cast and dried to a flexible membrane. The composition also included alternative plasticizer, e.g. dimethyl phthalate, diethyl phthalate, or tris butoxyethyl phosphate, and other inorganic filler adjuncts, e.g. fumed alumina or silanized fumed silica, to enhance the physical strength of the separator membrane and to increase the level of electrolyte solution absorption.
