摘要： In a secondary battery (1) comprising a battery case (2) for accommodating an electrode plate group (3) and an electrolyte, with one open end of the battery case (2) being sealed with an assembled sealing plate (11) that accommodates a safety mechanism (17) for exhausting pressure in the event of pressure build-up in the battery case (2) exceeding a predetermined level, at least one part (13a) of vent holes (13a, 13b, 13c) in the assembled sealing plate (11) facing the inside of the battery case (2) is constituted of an aperture that results from formation of a turned-out portion (23), the distal end of the turned-out portion (23) being allowed to abut on an insulating plate (4a) that makes contact with one end of the electrode plate group (3) so as to restrict movement of the electrode plate group (3). This can prevent malfunctioning due to displacement of the electrode plate group (3) when an impact or vibration is applied.

The electrode unit includes a positive electrode and a negative electrode, each made up of a collector and electrode material paste coated thereon, wound around with a separator interposed therebetween. The closure assembly includes a metallic filter that forms an internal terminal and accommodates a safety mechanism provided in case of abnormal pressure rise caused by overcharging etc, a resin inner gasket, and a metallic cap that forms an external terminal superposed upon one another. A resin inner gasket is attached to the metallic filter and the end edge of the metallic filter is crimped to provide a seal. The metallic filter and all the metallic parts encased in the metallic filter are joined together by welding. This closure assembly design enables high power output and high-current discharge of the battery with low resistance.

摘要： A battery pack is made up of a plurality of flat prismatic batteries arranged face to face, each battery having one electrode terminal protruding from one end face in the height direction of the battery case and this end face or a side face of the battery serving as the other electrode terminal. The connector for electrically connecting adjacent prismatic batteries includes a flat part that is welded to one electrode terminal of one prismatic battery of the adjacent prismatic batteries, and a cylindrical part that is fitted onto and welded to the other electrode terminal of the other prismatic battery. The cylindrical part is formed in an attachment part that extends from the flat part through an upright part in the direction in which the batteries are aligned. The connector enables reliable electrical connection of the prismatic batteries despite possible variation in height of the electrode terminals.
