    摘要: By combining crimping fixing and laser welding, a collector attached to a substrate of an electrode assembly is fixed to a terminal. A negative electrode terminal 19A has a terminal portion formed on one side of a flange portion, and a cylindrical crimping member 19b on the other side. The cylindrical crimping member 19b is inserted through openings formed in a first insulating member, a sealing plate, a second insulating member, and a negative electrode collector 18a. The cylindrical crimping member 19b is crimped in a diameter-increasing direction, and is mechanically fixed in a countersunk hole 18c of the negative electrode collector 18a. A peripheral portion of a thin-walled portion 19d having a thickness smaller than those of other portions formed at the tip end portion of the cylindrical crimping member 19b is thoroughly adhered and welded by a high energy beam to the edge of the countersunk hole 18c.

    摘要: The method for manufacturing a sealed battery of the invention includes an ultrasonic fusion process whereby layers of a positive electrode substrate exposed portion 11 are ultrasonically fused to form a positive electrode fused portion 11a at the positive electrode substrate exposed portion 11, and layers of a negative electrode substrate exposed portion 12 are ultrasonically fused to form a negative electrode fused portion 12a at the negative electrode substrate exposed portion 12; and an electrode body formation process whereby a high-energy beam is directed at the positive electrode fused portion 11a to weld a positive electrode collector to the positive electrode fused portion 11a, and a high-energy beam is directed at the negative electrode fused portion 12a to weld a negative electrode collector to the negative electrode fused portion 12a, thus forming an electrode body in which a positive electrode collector is welded to one end of the electrode group and a negative electrode collector is welded to the other end. Thereby, the required weld strength is obtained despite a reduction in the energy for welding, and a sealed battery is obtained which has low internal resistance and in which internal short-circuiting is prevented.

    摘要: An object of the present invention is to provide a high-output prismatic secondary cell that excels in current collecting efficiency and provides for reliable and highly productive welding with a lower welding current at the time of resistive welding of a current collecting plate onto a core exposed portion of a flat electrode assembly having at both ends a positive electrode core and a negative electrode core. This object is realized by a prismatic secondary cell including: a flat electrode assembly comprising a plurality of first electrode cores and a plurality of second electrode cores, the first electrode cores protruding from one end of the flat electrode assembly while being directly laminated on top of each other, the second electrode cores protruding from another end of the flat electrode assembly while being directly laminated on top of each other; and a first current collecting plate arranged in a first electrode core collected area where the mutually directly laminated first electrode cores protrude, the first current collecting plate being resistive-welded on one plane parallel to a plane on which the first electrode cores are laminated. A first electrode core melt-attached portion where the mutually directly laminated first electrode cores are melt-attached is formed in an area distanced from the area in which the first current collecting plate is attached.
