摘要： The present invention relates to a construction of an explosion-proof safety vent for small-size non-aqueous electrolyte batteries such as prismatic lithium-ion secondary batteries or with an oval cross section hence with a small area of seal plate, and to a method of producing a seal plate. It aims at securing safety of a battery by allowing an explosion-proof vent to operate without fail with a simple construction at no sacrifice of the capacity. In order to fulfill this aim, it provides an explosion-proof safety vent wherein upper peripheral edge of an opening of a bottomed cell container made of metal and the periphery of a seal plate made of metal are hermetically sealed by laser welding, a rivet serving as a terminal is inserted in a through hole provided on the central portion of the seal plate and hermetically fixed by crimping via a gasket, an exhaust hole is provided between the terminal and the periphery of the seal plate, and the exhaust hole is closed by a metal foil. With such a simple structure, it allows the vent to operate without fail to prevent accident and also proposes a method of continuously producing seal plates in the form of a hoop.

摘要： Battery with a flexible laminate casing includes a means for fixing the electrode assembly (2) within the casing (1, 18). The fixing means may be a frame (19, 33, 38, 50, 54) attached to the periphery of the electrode assembly, or an insulating spacer (59, 69, 70, 77, 78) encased within the casing together with the electrode assembly such as to fill a space between one end of the electrode assembly and the casing. Alternatively, the fixing means may be constructed of a material with which the casing and the electrode assembly are joined together by applying heat and pressure, or may be an abutting surface (87h) provided to the casing (87) itself such as to make contact with one end face of the electrode assembly within the casing.

摘要： The present invention provides a sealed battery having a large capacity by using a thin safety valve device so as to increase a volume of a cell element. The sealed battery has a high safety owing to the thin safety valve device having an elastic valve element comprising an ethylene-propylene elastomer and thermoplastic resin particles dispersed in the ethylene-propylene elastomer. The elastic valve element is produced by mixing thermoplastic resin particles with an ethylene-propylene elastomer material, molding the mixture into a predetermined shape and, at the same time, crosslinking the ethylene-propylene elastomer material.
