    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： A method for manufacturing a rectangular cell is provided in which a rectangular case containing a power generating element is hermetically sealed by laser welding a sealing plate to an open end of the rectangular case. A sealing plate 2 formed into the same shape as the upper open end of a rectangular case 1 is laid on the upper open end, laser beams 3a to 3d are applied in a downward direction from the horizontal to a line of contact 4 comprising sides “a” to “d” including respective corners “e”, and the line of contact 4 is scanned with laser beams 3a to 3d thereby sealing the open end of the case with the sealing plate.

    摘要： To present a processing apparatus capable of forming an annular support portion for mounting a sealing plate on an elliptical battery case can at high precision and high productivity, and a structure of an elliptical battery using an elliptical battery case can.An elliptical battery case can 10 is rotatably held by a case can support mechanism 13. The battery case can 10 is rotated about its tubular center by a case can rotary mechanism 18. Two groove forming rollers 23, 24 are mounted on an oscillatable roller support lever 28. The roller support lever 28 traces the shape of the outer circumference of the battery case can 10, and oscillates within a plane orthogonal to the tubular center of the battery case can 10, and receives a pressing force from a pressurizing device 29 to press the both groove forming rollers 23, 24 against the outer circumference of the battery case can 10. As a result, an annular groove 50 is formed in the outer circumference of the elliptical battery case can 10, and an annular support portion 40 is formed in the inner circumference.
