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 present invention aims to provide a method for insulatively covering the side surfaces and bottom of a prismatic outer can in a simple manner. This can be realized by adopting the following configuration: a prismatic cell including a prismatic outer can having an opening at the top thereof; a sealing body for sealing the opening; and positive and negative electrode external terminals that are protruded from and insulated from the sealing body, wherein the prismatic outer can is covered on the side surfaces and entire bottom with a piece of folded insulation sheet. Preferably, the bottom of the prismatic outer can is covered with only one piece of the insulating sheet, and all edges of the insulating sheet is positioned above the bottom of the outer can.

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.
