Abstract: A metallic plate and an electrode of, e.g., a polymer lithium ion secondary cell are welded to each other securely so as to further improve the reliability and durability. An upper metallic plate (7a) and a lower metallic plate (9a) of a positive plate are so welded to an electrode (3) of the positive plate that they vertically sandwich the electrode (3). Similarly, an upper metallic plate (7b) and a lower metallic plate (9b) are so welded to an electrode (5) of a negative plate that they sandwich the electrode (5). Thus defective electric resistance welding is prevented.

Abstract: PURPOSE:To simplify the forming process of a case body and to permit the formation of a cover part and the punching of a vent by using the same process and to facilitate production by providing the vent to the cover part allowing simple formation compared with the case body. CONSTITUTION:A vent 16 for filling an electrolyte is provided in an appropriate position of a cover part 14 for sealing the upper opening of a square case body 12. A sealing steel ball 18 is welded for sealing. The vent 16 is provided in the bottom part of a truncated cone-like recessed part formed on the cover part 14. In fabricating a sealed cylindrical battery 10, the upper opening of the body 12 housing electrode materials is covered with the cover part 14. Laser seam welding 24 is applied to the peripheral edge of the cover part 14 with the body 12 standed to fix the cover part 14 to the body 12. Next, the electrolyte is filled from the vent 16 with the body 12 retained under the same standing posture. The steel ball 18 having the diameter slightly larger than the aperture of the vent 16 is abutted to the vent 16. The ball 18 is welded by using the welding method such as resistance welding, etc., to seal the vent 16. Thus processes are simplified to enhance the productivity of battery fabrication work.
