摘要： It is aimed to provide a battery pack capable of securing safety by preventing A battery contained in the battery pack from entering a burning state even if the battery releases high-temperature gas in an abnormal state. An exhaust duct 1C for permitting the flow of gas released from the battery is provided and the gas is exhausted to the outside after reducing the temperature thereof in the exhaust duct 1C. A flow passage area of the exhaust duct 1C is in the range of not less than 0.5 mm2 and not more than 15 mm2 per 1 Ah of the battery capacity. The exhaust duct 1C is provided with a gas cooling portion 1L and a spark trapping portion 1M.

摘要： A positive electrode plate and a negative electrode plate are spirally wound with a separator interposed therebetween to form an electrode group 3 having a circular shape or an oval shape. Next, a center core member 2 for applying a pressure to the electrode group 3 is inserted in a winding core hole 6 of the electrode group 3. Thereafter, the electrode group 3 is deformed into a flat shape. Then, the flat electrode group 3 is accommodated in a rectangular flat armoring can 4 with a base and an opening portion of the armoring can 4 is sealed, thereby producing a rectangular flat secondary battery.

摘要： The present invention relates to an improvement to an assembled sealing member used for batteries. The present invention intends to reliably stop charging and discharging particularly in a battery with high capacity and high output performance, when a trouble occurs in the battery. An assembled sealing member for a battery according to one embodiment of the present invention includes: (i) a conductive cap having an external terminal; (ii) an electrically conductive film disposed so as to face a power generation element and being connected to one of electrodes included in the power generation element; (iii) an electrically conductive valving member disposed between the cap and an electrically conductive film; and (iv) a thermally expandable material disposed between the valving member and the electrically conductive film. The electrically conductive film and the valving member are bonded to each other in an electrically connected state at least one predetermined point, and when the thermally expandable material is expanded to be predetermined times larger, the bond between the electrically conductive film and the valving member ruptures to break the electrical connection between the electrically conductive film and the valving member.
