Collectors are joined to the leads on both sides of the electrode plate group, and include connection protrusions formed so as to protrude outside. A bag-shape battery case containing the electrode plate group is joined to the collectors such that only the connection protrusions of the collectors are protruded outside the bag-shaped battery case. A battery module is constituted by placing a plurality of the cells, connected together, into a prismatic battery case.

摘要： A prismatic battery module includes a prismatic battery case having a plurality of prismatic cell cases connected to one another through separation walls, a planar electroconductive connector forming part of the separation wall between the cell cases, an electrode plate group arranged in each cell case, and an electrolyte placed in each cell case. Lead portions of positive electrode plates and negative electrode plates of the electrode plate group are directly connected to the electroconductive connector. The prismatic battery module requires fewer connection points and provides shorter electrical communication paths, thereby reducing internal resistance.

摘要： A prismatic sealed battery module includes: a prismatic battery case; an electrode plate group constituted by alternately layering positive and negative electrode plates with a separator arranged therebetween; and an electrolyte. The positive or negative electrode plates protruding from each end face of the electrode plate group are bonded to a collector member. A metal connector is fixed to the central part of the collector member facing the inner surface of the side end wall of the battery case. The collector member is connected, at the metal connector, to an external terminal using an externally connecting bolt.

摘要： A prismatic sealed battery has a prismatic battery case (3) which includes a plurality of prismatic containers (4) coupled in a row via partitions (5), electrode plate assemblies (8), and collectors (10) which are joined to lead portions on both sides of the electrode plate assemblies (8). Each container (4) contains the electrode plate assembly (8) to which said collectors 10 are joined. An opening (21) is formed in at least one side wall (20) of the prismatic battery case (3) and in a position where each partition (5) is disposed, in such a manner as to face the containers (4) on both sides, and a conductive connection member (23) disposed in the opening (21) is connected to the collectors (10, 10) on both sides of the partition (5). Since the current-carrying path between the electrode plate assemblies (8) becomes short, internal resistance decreases, and hence internal resistance per cell (2) is reduced. Even and full use of the whole electrode plate assembly (8) achieves higher power output.

摘要： A secondary battery comprises a power generating element, a battery case including a gas release hole, and a valve safety device configured to close the gas release hole and release gas out of the battery case when inner pressure in the battery case exceeds a predetermined value. The safety valve device comprises a valve member and a holding member. The valve member includes a sealing portion hermetically making contact with a sealed surface around the gas release hole, and the holding member is fixed to the battery case to elastically press the sealing portion by its elastic deformation.

摘要： The battery pack uses a restraining tool capable of secure restraint despite relatively low rigidity to achieve weight and cost reductions. The battery pack is formed of a plurality of parallel arranged battery modules (2), each consisting of a plurality of cells (5) electrically connected in series and coupled together in one piece with gaps (8) formed therebetween (5, 5), each cell being formed of elements for electromotive force encased in a prismatic case. The restraining tool includes connecting members (4) extending through the gaps (8) at both ends of the parallel arranged battery modules (2) and between two given cells (5, 5).
