    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： Each battery module 100 includes a holder 20 accommodating cells 10 and made of a thermal conductive material, and a rectangular solid case 30 accommodating the holder 20. The holder 20 includes containers 21, in each of which one of the cells 10 is accommodated. The case 30 has a first side surface 30a and a second side surface 30b, which are parallel to side surfaces of the containers 21 of the holder 20, and face each other. The battery pack 200 is formed by stacking the battery modules 100 in a direction that the first side surface 30a and the second side surface 30b overlap each other. Spacers 50a and 50b, each of which has a predetermined width, are provided between adjacent two of the battery modules 100, at both ends of the first and second side surfaces 30a and 30b of the case 30 in a width direction, along a direction perpendicular to the width direction. The spacers 50a and 50b form a gap 60, through which a cooling medium flows, between the first and second side surfaces 30a and 30b.
