摘要： A cell includes an electrode plate group which is formed by laminating a positive electrode plate and a negative electrode plate with a separator interposed between them, and includes leads protruding toward directions opposite to each other from one side of the positive electrode plate and the negative electrode plate. 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.
