Part b) in Figure 2 shall be satisfied,
A heat-shrinkable resin tube having an inner diameter slightly larger than the outer diameter of the sealing plate was used for the lower sealing packing, and the battery was assembled by heating the tube to bring it into close contact with the outer edge of the sealing plate.

The heat-shrinkable resin has a height C that is larger than the height d of the folded part of the sealing plate, and has a thickness e that is extremely smaller than the thickness a' (in Fig. 2) of the conventional insulation sealing Ropanoking. The tube is placed over the upper end of the folded portion of the sealing plate 7', which has a larger outer diameter than the conventional sealing plate 7', and the resin tube is shrunk by applying hot air.
The resin tube and the sealing plate are brought into close contact with each other, and the lower side of the folded part of the sealing plate is covered with the lower sealing packing 6.
b. Further, the lower sealing packing 6a was positioned up to the upper side of the folded portion of the sealing plate.
