１１の折曲により封口して製造している。 For example, a cylindrical nickel-cadmium battery 1 as shown in FIG. After being inserted into the shaped outer can 6, a seam portion 7 is formed in the outer can. Thereafter, the electrolytic solution is injected, the sealing lid 9 with the anode terminal cap 8 attached is attached to the opening of the outer can 6 via the insulating packing 10, and then the opening edge 11 of the outer can 6 is bent to seal it. Manufactured.

る。 In this manufacturing method, the outer diameter of the spiral electrode body 5 is made slightly smaller than the inner diameter of the outer can 6 so that the spiral electrode body 5 can be inserted smoothly into the outer can 6. This is to prevent the outer peripheral portion of the spiral electrode body 5 from coming into contact with the inner peripheral surface of the outer can 6 when the spiral electrode body 5 is inserted, thereby preventing the electrode plate from collapsing. Therefore, a small gap 12 is created between the outer can 6 and the spiral electrode body 5. However, due to the existence of this small gap 12, the spiral electrode body becomes loose after being inserted into the outer can, and the tightness of the negative and anode plates decreases, which adversely affects the battery performance. In order to eliminate this inconvenience and to simplify the assembly process, a method may be considered in which the outer periphery of the spiral electrode body is taped to maintain the tightness. However, in this method, since the small gap 12 remains and the spiral electrode body can swing within the outer can, the lead pieces 13,
New problems such as tearing of 14 will arise.

高さの管理上好ましくない。 Therefore, in order to deal with the above-mentioned problem, a method as shown in FIG. 2 can be considered. That is, FIG. 2 is a state diagram in which the cylindrical battery 1 is being penetrated through the through hole 16 of the die 15, and the battery 1 with the outer diameter dimension A is shrunk to the minimum opening dimension B of the die 15 by extrusion with the punch 17. It is something that goes through a period of time. The battery 1' manufactured in this way is reduced in diameter to the minimum opening dimension B of the die 15, as shown in FIG. As shown in the figure, the bottom surface 6 bulges downward, which is unfavorable in terms of battery shape and battery height management.

The cylindrical battery outer can has a main cylindrical portion having an outer diameter smaller than the insertion opening dimension of the die and larger than the minimum opening dimension of the die,
The diameter of the main cylindrical portion is reduced by forming the main cylindrical portion into a shape having a diameter-reduced cylindrical portion at the lower end having a diameter smaller than the minimum opening dimension, and passing the battery through the through hole of the die after battery assembly.

小さいものでもよい。 An embodiment of the present invention will be described below with reference to the drawings. Fig. 4 is a front view of a battery provided with a battery outer can used in the present invention. In this drawing, the battery 20 has an outer can 21, which has an outer diameter smaller than the opening dimension A of the through hole 16 of the die 15 and larger than the minimum opening dimension B of the through hole 16 shown in FIG. It is formed to have a main cylindrical portion 21a having a diameter C, and a lower end reduced diameter cylindrical portion 21b having a diameter equal to or less than the minimum opening dimension B. The battery 1 shown in Fig. 1 is placed in the outer can 21.
Similarly, the spiral electrode body 5 as a spiral electrode body is housed and sealed, and the battery 20 is assembled and formed.
This battery 20 is inserted into the through hole 16 of the die 15 as shown in FIG. The diameter is reduced to dimension B. The front view of the battery 20 whose diameter has been reduced in this way is shown in the sixth figure.
As shown in the figure. As is clear from this drawing, the present invention forms a lower end diameter-reduced cylinder portion equal to the minimum opening dimension B of the through hole 16 at the center of the bottom of the outer can.
Since the distortion of the outer can due to the diameter reduction can be absorbed by the side surface formed by the lower diameter reduced cylinder part and the bottom peripheral edge of the outer can, the bottom surface 21' of the outer can 21 does not deform.
Note that the diameter of the lower end reduced diameter portion 21b may be smaller than the minimum opening dimension B.

After assembling the battery,
Since the diameter of the main cylindrical portion is reduced by passing through the die, the distortion of the outer can due to diameter reduction can be reduced by reducing the diameter of the lower end diameter-reducing cylindrical portion provided at the center of the bottom of the outer can and the bottom periphery of the outer can. Since it can be absorbed by the side surface formed by the outer battery can, the bottom surface of the battery outer can does not bulge, and the diameter of the battery outer can can be reduced.
