漏れ出る等の問題があつた。Structures of conventional examples and their problems In order to reduce the cost of storage batteries, the monoblock case molded from synthetic resin such as ABS resin was replaced with a case made of film or sheet thermoplastic resin, such as polyethylene, as shown in Figure 1. Several proposals have been made to replace the bag-like exterior body. In the figure, 1 is two polyethylene films, and 2 is a bag-like exterior body. In this case, an electrode plate group 7 consisting of a rectangular positive electrode plate 4, a negative electrode plate 5, and a separator 6, each having a resin-coated pole column 3, 3' welded to a part of the upper part, is acid-resistant and heat-welded. The pole column 3 is inserted through the bottom opening 2a of the bag-like exterior body 2 made of a polyethylene film with a high temperature, and is inserted through the top openings 2b, 2c of the bag-like exterior body 2.
3' protrudes outward, and then the bag-like exterior body 2
The space between the pole column 3 and the bottom opening 2a is sealed by thermal welding, and after sealing, an electrolytic solution is injected through the opening 2e of the unwelded convex portion 2d, which serves as a safety valve of the bag-like exterior body, to form a battery. there was. However, since the material of the exterior body is a thin film or sheet, the corner portion 8 of the lead alloy lattice body 8 of the electrode plate group 7
a, vibrations and shocks cause tears and pinholes in the bag-like exterior body 2, making it impossible to maintain airtightness. In the worst case scenario, the electrolyte inside the battery may leak out.
