摘要： A galvanic cell (10) is disclosed. Generally, the cell includes an alkali metal anode (12), which electrochemcially oxidizes to release alkali metal ions, and a cathode (14), which is configured to be exposed to an electrolyte solution. A water-impermeable, alkali-ion-conductive ceramic membrane (20) separates the anode (12) from the cathode (14). Moreover, an alkali-ion-permeable anode current collector (16) is placed in electrical communication with the anode (12). In some cases, to keep the anode (12) in contact with the current collector (16) as the cell (10) functions and as the anode (12) is depleted, the cell (10) includes a biasing member (22) that urges the anode (12) against the current collector (16). To produce electricity, the galvanic cell (10) is exposed to an aqueous electrolyte solution, such as seawater, brine, saltwater, etc.

摘要： A multi-functional battery separator comprises two or more active separator layers deposited from different polymer solutions to form a multilayered unitary structure comprising a free-standing film, a multiplex film on one side of a porous substrate, or separate films or multiplex films on opposite sides of a porous substrate. In a preferred embodiment, the cascade coating method is used to simultaneously deposit the active separator layers wet so that the physical, electrical and morphological changes associated with the polymer drying out process are avoided or minimized. The multi-functional separator is inexpensive to fabricate, exhibits enhanced ionic conductivity and ionic barrier properties, and eliminates gaps between individual layers in a separator stack that can contribute to battery failure.

摘要： The present invention provides compositions, formulations and methods providing for the effective dissolution of inorganic fluorides in solvents via incorporation of a dissociating agent component. Dissociating agents of the present invention participate in chemical reactions in solution, such as complex formation, acid-base reactions, and adduct formation reactions, that result in enhancement in the dissolution of inorganic fluorides in a range of solvent environments. Dissociating agents comprising Lewis acids, Lewis bases, anion receptors, cation receptors or combinations thereof are provided that significantly increase the extent of dissolution of a range of inorganic fluorides, particularly inorganic fluorides, such as LiF, that are highly insoluble in many solvents in the absence of the dissociating agents of the present invention.
