  • Patent number: 7172832
    Abstract: A sealed battery (100) includes a power generation element (120), a battery case (110), and an external positive terminal (150) fixed to a first case wall (110a). Case side faces (110c, 110d) serve as external negative electrode portions providing an electrical connection to a negative electrode of the power generation element (120). The external positive terminal (150) has extended joint portions (155) extending in a direction perpendicular to the first case wall (110a). The extended joint portions (155) are laid to overlap from outside with and connected to the external negative electrode portions when the external positive terminal (150) of the sealed battery (100) is brought into contact with a second case wall (110b) of another sealed battery (100).

  • Patent number: 7160643
    Abstract: A battery pack includes a plurality of batteries interlocked linearly through a connector. The connector includes an inner peripheral portion to be welded to one battery, and an outer peripheral portion, provided outside the inner peripheral portion, to be welded to the other battery. The inner peripheral portion and the outer peripheral portion have a step in between, and the step places the inner peripheral portion in a concave portion of the connector. The inner peripheral portion of the connector is located interiorly of a caulking convex strip provided at an end face of one battery, and an inner peripheral portion is connected to the battery end face through welding without coming in contact with the caulking convex strip. The outer peripheral portion is connected to an outer peripheral portion of a battery end face of the other battery through welding.

  • Patent number: 7090945
    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.
