    摘要: A sealed cell having a safety mechanism is provided. The safety mechanism has a non-resealable valve structure formed in a sealing plate that seals the cell. The valve structure is broken as soon as the internal pressure reaches or exceeds a predetermined value so as to permit the internal gas to be released outside. The valve structure has at least one dome protruding toward the interior of the cell, which in turn has at the periphery thereof a break groove for facilitating the breakage of the valve structure. This makes the valve structure highly responsive to the internal pressure and causes to form a break-opened orifice of a sufficient area at the time of operation in response to the increased internal pressure. The valve structure is not unnecessarily broken by the impacts of, for example, dropping. As a result, the safety of the sealed cell is significantly improved.

    摘要: A method for manufacturing a sealed battery for the invention uses an outer can 15 with an opening and a sealing plate 16 provided with a rising part which rises perpendicularly from the middle of a flange on the entire circumference of or a part of the fitted face with the battery outer can 15. The method includes inserting the sealing plate 16 into the opening of the battery outer can 15 so that the top faces of both the battery outer can 15 and the flange of the sealing plate 16 are substantially in the same plane, and irradiating the fitted part of the opening of the battery outer can 15 and the sealing plate 16 with a high energy beam for welding.

    摘要: A negative electrode terminal includes an outer terminal of a solid flat rivet shape and an inner terminal of a hollow flat rivet shape. A hollow axle portion of the inner terminal is inserted in a first insulating member, an opening bored in a sealing plate, and a second insulating member so as to be insulated from the sealing plate. A columnar axle portion of the outer terminal is inserted into the hollow axle portion of the inner terminal and crimped thereto, so that a radially bulge-deformed portion is formed in an intermediate portion of the columnar axle portion. The hollow axle portion deforms into a shape matching the radially bulge-deformed portion and is crimped to the columnar axle portion, and its tip is curling-formed to match a curved surface between a brim portion and the columnar axle portion of the outer terminal.

    摘要: A cell safety valve which has a thin valve plate formed on a sheet-shaped sealing plate for sealing the cell such that if the inner pressure of the cell exceeds a predetermined value, the valve plate breaks to release a gas in the cell to the outside, in which the valve plate has a dome-shaped dome portion formed thereon and, at its middle or near it, a break groove formed for facilitating the breaking of the valve. By this construction, it is possible to prevent the electrolyte from leaking while reducing the cell-to-cell difference in the operating pressure of the safety valve and ensuring a sufficient open area at the time of the operations of the safety valve.
