Patent ID: 8080328

Claim:
A secondary battery module having a single battery housed in a battery container made of a flexible member or a plurality of unit cells each being disposed in a layer-stacked state, housed in a battery container made of a flexible member and connected to one another in series or in series and parallel comprising: a connecting member placed so as to face a single battery or a unit cell disposed at one end of said plurality of unit cells and to connect said single battery or said unit cell disposed at one end of said plurality of unit cells with an external output terminal; and a pushing member placed between said single battery or said unit cell disposed at one end of said plurality of unit cells and said connecting member; wherein said pushing member, when said single battery or any one of said plurality of unit cells expands, breaks off the connection established by said connecting member between said single battery or said unit cell disposed at one end of said plurality of unit cells and said external output terminal, wherein said connecting member comprises a first connecting member having through-holes being placed so as to face said single battery or said unit cell disposed at one end of said plurality of unit cells and a second connecting member disposed on a side of said first connecting member opposite to said pushing member so as to face said first connecting member and having a coupling portion with said first connecting member, and wherein said pushing member has projected portions being able to pass through said through-holes formed in said first connecting member, and wherein one of said first connecting member and said second connecting member is connected to said single battery or said unit cell disposed at one end of said plurality of unit cells and another of said first connecting member and said second connecting member is connected to said external output terminal and, when said single battery or any one of said plurality of unit cells expands, said projected portions of said pushing member pass through said through-holes formed in said first connecting member to cause rupture of said coupling portion, and wherein a central portion of said second connecting member is projected to a side of said first connecting member and said coupling portion is formed in the projected central portion.
