はない。Next, the manufacturing method will be described. First, as shown in FIG. 1, the flange portion 11B 1 and the skirt portion 1 are made to project outward from the entire circumference of the open end of the thin cup-shaped container main portion 11A.
1B 2 and a container main body 11 in which a sealing overhanging part 11B is formed, and a lid main part 12A that covers the opening of the container main part 11A.
A lid member 12 including a sealing cylinder portion 12B is prepared as a constituent member of the battery container 10. Next, in a glove box (not shown), the electrode laminate 13 is stored in the container main portion 11A of the container main body 11, and then the electrolytic solution 17 (for example, SOCl containing solute LiAlCl 4 1.5M is contained in the container main portion 11A).
2 ) is injected, and the lid member 12 in which the cathode terminal 21 is attached to the skirt portion 11B 2 of the overhanging portion 11B of the container body 11
The closing cylinder part 12B is fitted. At this time, the lid member 12
Is lightly tapped with a wood punch to cause the flange portion 11B 1 and the sealing cylinder portion 12B to overlap with each other, and the tip end edge portion of the skirt portion 11B 2 and the tip end edge portion of the sealing cylinder portion 12B are butted against each other to form the lid member 12. The container body 11 is positioned and fixed.
When the flange portion 11B 1 and the sealing cylinder portion 12B come into contact with each other, the electrolytic solution 17 in the container body 11A oozes out by a capillary phenomenon through the overlapping portion 19 between the flange portion 11B 1 and the sealing cylinder portion 12B. Since the progress of the electrolytic solution is blocked by the void a, the electrolytic solution 17 hardly leaks within a few minutes. Further, since the skirt portion 11B 2 of the container body 11 is provided with a taper, the tubular portion 12B of the lid member 12 is firmly fitted to the skirt portion, and the lid member 12 is easily separated from the container body 11. There is no.

進める必要がある。After attaching the lid member 12 as described above, the battery container 10 is taken out from the glove box, and the abutting portion 18 between the tip end edge portion of the skirt portion 11B 2 and the tip end edge portion of the sealing tube portion 12B is provided around the entire circumference. The battery container 10 is sealed by laser welding over a short time. When carrying out this laser welding, the temperature of the battery rises rapidly due to heat conduction from the welded portion, so it is necessary to proceed with the work while cooling with a cooling gas (air or nitrogen gas).

Further, when the bending process is performed in this manner, the welded portion is hidden behind the peripheral wall portion of the container main portion 11A, so that it is possible to prevent an external force from acting on the welded portion and prevent damage to the welded portion. [Effects of the Invention] According to the present invention, the gap can extend the time until the electrolytic solution oozes out from the polymerized portion between the sealing overhanging portion and the sealing tubular portion due to the capillary phenomenon. Therefore, the electrolytic solution does not leak from the polymerized part of the battery container until the abutting part of the leading edge of the skirt part and the leading edge of the sealing tube is welded, and the amount of the electrolytic solution is It is possible to prevent the amount of the gas from decreasing or the electrolytic solution from being decomposed by heat during welding to generate corrosive gas or toxic gas.
