Abstract: Systems and methods for configuring tabs on a rechargeable battery may include a current collector comprising one or more collector foil and one or more tabs connected to the collector foil for conveying generated current from the current collector. The tabs may be configured to extract greater capacity from the battery electrodes so that the resulting battery may exhibit higher performance. The tabs may be configured so that the length of the tab is greater than the height of the collector foil so the tab may cover the height of the collector foil and may protrude from the foil.

Abstract: A magnesium battery electrode assembly is described, including a current collector comprising a carbonaceous material and an electrode layer comprising an electrode active material disposed on the current collector.

Abstract: A water-soluble binder useful for preparing an electrode for either primary or secondary batteries, having either aqueous or non-aqueous electrolyte, contains polyacrylamide and at least one copolymer selected from carboxylated styrene-butadiene copolymer and styrene-acrylate copolymer. The water-dispersible binder eliminates or reduces the need for organic solvents during preparation of an electrode made of a particulate active electrode material. The binder exhibits good chemical resistance, adhesive properties, flexibility and resilience, making it well suited for use in preparing batteries having a spirally wound electrode assembly.

Abstract: An electrolyte for nonaqueous cells containing a solvent comprising at least one diether containing the sequence O.sub.1 C.sub.1 C.sub.2 O.sub.2 wherein two or three contiguous atoms are part of a five-, six- or seven-member ring system having as the remaining ring atoms carbon, or carbon and hetero atoms, with a methyl group bonded to an oxygen atom O.sub.1 and/or O.sub.2 when said oxygen atom is not included in the ring structure.

Abstract: Low temperature molten compositions comprised of a mixture of a metal halide, such as aluminum trichloride, and a hydrocarbyl-saturated onium salt, such as trimethylphenylammonium chloride, are useful as electrolytes in electrochemical cells.

Abstract: The invention relates to the use in a non-aqueous electrochemical cell of a conductive electrolyte comprising an ionizing solute dissolved in a mixture of a selected halide of an element of Group IV to Group VI of the Periodic Table and a cosolvent. The selected halide serves the dual function of acting as a solvent for the solute and as the active cathode depolarizer of the cell.
