摘要： A secondary battery includes a battery can 1 and a battery lid that seals an opening of the battery can 1. In a space defined by the battery can 1 and the battery lid 3, a power generation element group 6 formed by winding a positive plate and a negative plate are disposed. The battery can is formed in a shallow, bottomed rectangular shape, in which a length of one side perpendicular to a bottom of the shallow bottomed rectangle is smaller than lengths of other two sides. In the opposite ends of the power generation element group 6, uncoated sections 6A and 6B where no active material mix is coated are exposed. The power generation element group 6 is disposed so that the uncoated sections 6A and 6B are positioned directly above the through holes 1B. The connection members electrically and mechanically connected to the uncoated sections 6A and 6B are included to provide electrical continuity with an outside of the battery through the through holes 1B.

摘要： A secondary battery includes a battery casing accommodating an electricity-generating element group, and a battery cover having through-holes and sealing an opening in the battery casing. A first face at one end of each of positive and negative electrode connecting plates, which are each formed from a single plate of metal, is connected to a non-coated section of the electricity-generating element group. A second face at the other end of each of the positive and negative electrode connecting plates is a face onto which a busbar is welded, and the second face is exposed outward from one of the through-holes. Insulating base materials are interposed between THE positive and negative electrode connecting plates and an outer circumference of each through-hole, the insulating base materials and the battery cover are connected by brazing, and the insulating base materials and the positive and negative electrode connecting plates are connected by brazing.

摘要： A secondary battery includes a gas release valve located at a battery container housing a power generating element, wherein: the gas release valve includes a valve disk caused to expand outward by internal pressure in the battery container; wherein a plurality of grooves are formed at the valve disk in order that a plurality of valve element pieces become fractured along the grooves when the valve disk expands due to the internal pressure; and a scatter-deterring portion is formed at the valve disk in order to prevent the fractured valve element pieces along the grooves from scattering away from the valve disk.
