摘要： The present invention provides a flat cell that employs strip-shaped electrode plates on which an active material layer has been formed by coating paste or by electrolytic deposition on both sides or one side of a core material consisting of a metal foil. By constructing an electrode group having an oval cross section by spirally winding in a manner folding, a strip-shaped positive plate having a striped recessed portion of a predetermined width of which the center is positioned on the line of folding formed on the active material layer at least the inner side of at least the inner-most folded portion close to a core portion, and a strip-shaped negative plate with a separator interposed, reduction in the battery capacity due to breakage of the electrode plates and/or peeling off and dropping of the active material layers and failure due to internal short circuit as has previously been caused when assembling an electrode group having an oval cross section can be completely eliminated, thus drastically improving the reliability of flat cells, especially flat type lithium-ion secondary batteries.

摘要： A secondary battery exhibiting a long cycle life and comprising a negative pole activating material made of lithium or zinc is provided, the battery at least having a negative pole made of lithium or zinc serving as the negative pole activating material, an electrolyte (electrolytic solution), a separator, a positive pole made of a positive pole activating material, a collecting electrode and a battery case, wherein at least the surface of the negative pole is covered with a film having a structure which allows ions relating to the battery reactions to pass through. Since growth of dendrites of lithium or zinc at the time of charge can be prevented, short circuiting between the negative pole and the positive pole can be prevented. Therefore, the charge/discharge cycle life can significantly be lengthened. As a result, a lithium secondary battery, a nickel-zinc secondary battery, an air-zinc secondary battery, a bromine-zinc secondary battery and a silver oxide-zinc secondary battery of long cycle life can be manufactured.

摘要： A dry preunit (10), includes a plurality of cells (110, 112, 114) in a true bipolar configuration, which are stacked and bonded together, to impart to the device an integral and unitary construction. Each cell (114) includes two electrically conductive electrodes (111A, 111B) that are spaced apart by a predetermined distance. The cell (114) also includes two identical dielectric gaskets (121,123) that are interposed, in registration with each other, between the electrodes (111A, 111B), for separating and electrically insulating these electrodes. When the electrodes (111A, 111B), and the gaskets (121, 123) are bonded together, at least one fill gap (130) is formed for each cell. Each cell (114) also includes a porous and conductive coating layer (119, 120) that is formed on one surface of each electrode. The coating layer (119) includes a set of closely spaced-apart peripheral microprotrusions (125), and a set of distally spaced-apart central microprotrusions (127). These microprotrusions (125, 127) impart structural support to the cells, and provide additional insulation between the electrodes. An energy storage device (10A) such as a capacitor, is created with the addition of an electrolyte to the gap (130) of the dry preunit (10) and subsequent sealing of the fill ports.

摘要： Systems and methods which provide flexible zinc ion (Zn-ion) battery configurations with shape memory are described. For example, embodiments of flexible shape memory yarn batteries (SMYBs) may be fabricated using shape memory material wire, filament, and/or fiber and flexible conductive material yarn as flexible substrate materials. In accordance with some embodiments, Nickel-Titanium-based alloy wire may be coated with a zinc material to provide a flexible anode electrode for a SMYB. Additionally or alternatively, flexible stainless steel (SS) yarn may be coated with a manganese dioxide (MnO2) material to provide a flexible cathode electrode for a SMYB of embodiments. An aqueous electrolyte may be combined with the flexible cathode and anode electrodes to provide a SMYB in accordance with the concepts herein. The aqueous electrolyte may, for example, comprise a polymer gel electrolyte (e.g., gelatin-borax polymer gel electrolyte).
