摘要： The object of the present invention is to provide a closed battery capable of rapidly releasing the internal pressure thereof and at the same time disconnecting the current to effectively prevent itself from temperature rising and exploding so that in such a completely closed battery it may assure the safety and reliability thereof, when the internal pressure is elevated due to short circuit, overcharge, reverse charge, or the like. A valve element 5 is provided with a slit 3 between the circumference thereof and a metal substrate 1. When the internal pressure of a battery is elevated, the valve element 5 is smoothly raised up together with a metal foil 2 from a bending fulcrum portion 4 to thereby cut a lead wire 6 or permit a braze portion 8 to detach from the lead wire 6, thus disconnecting the current reliably. Then, the metal foil which usually closes the slit formed around the circumference of the valve element 5 is allowed to burst stably and accurately at a prescribed pressure to thereby form a valve opening portion 7 so that the internal gas of the battery can be discharged.

The formation of a valve element 5 whose center is eccentric to the center of a metal substrate 1 produces a slit 3 having a large width portion around the circumference of a valve element 5. When the internal pressure of a battery is elevated, the valve element 5 is smoothly raised up together with a metal foil 2 from the bending fulcrum portion 4 to thereby cut a lead wire 6 or permit a braze portion 8 to detach from the lead wire 6, thus reliably disconnecting the current. Then, the metal foil is allowed to burst stably and accurately at a prescribed pressure to thereby form a valve opening portion 7 so that the internal gas of the battery can be discharged. Thus, the battery can previously be prevented from exploding.

摘要： Clad material comprises a metal substrate which is provided with a multiplicity of perforated openings therein and a metal foil which is laminated on the metal substrate to close the perforated openings. To produce such a clad material, at least one surface of the metal substrate and corresponding one surface of the metal foil are respectively subjected to a dry etching and the metal substrate and the metal foil are laminated in such a manner that the etched surfaces face each other. Alternately, only one surface of the metal substrate is subjected to a dry etching and the metal substrate and the metal foil are laminated in such a manner that the etched surface of the metal substrate defines a laminating surface. It may be possible to provide a nickel plating on the metal substrate or the metal foil. The clad material can be effectively used for producing safety valve chips which rupture accurately at low pressures which fall in a stable pressure range on a mass production basis.
