ABSTRACT:
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 which are joined to the leads on both sides of the electrode plate group, and include connection protrusions formed so as to protrude outside, and a bag-shape battery case containing the electrode plate group joined to the collectors such that only the connection protrusions of the collectors are protruded outside. A battery module is constituted by placing a plurality of the cells in a prismatic battery case while the connection protrusions of the collectors of the cells are connected with each other, thereby making the current-carrying path between the electrode plate groups straight and short and increasing the output.
