Abstract

PURPOSE:To prevent the leakage of an electrolyte from an electrode pole seal section and the dissipation of the electrolyte from a film by covering an electrode plate group with a laminated film, connecting part of a lead film or a lead plate to an electrode pole, and sealing them with lead or lead alloy. CONSTITUTION:An electrode plate group is covered with a three-layer laminated film 4 applied with a lead film 1 on the center section, a polypropylene film 2 on the thermal deposition surface, and a polyester film 3 on the outer surface. An insulating layer 7 not containing the lead film is used for the film at the center section of a battery to maintain the insulation of a positive electrode plate 5 and a negative electrode plate 6. An electrode pole seal section connects and seals the periphery of an electrode pole 8 to the electrode pole 8 with solder at the lead film 1 and the solder section 9 at the center section of the laminated film 4, epoxy resin 10 is poured into the upper section, and chlorinated polypropylene is coated on the epoxy resin 10 to make the thermal deposition complete. The periphery of the laminated film 4 is then thermally deposited with a thermal deposition section 11. The leakage and dissipation of the electrolyte can be thereby prevented.

点を有していた。Problems to be Solved by the Invention In such a pole-column sealing method, it is possible to completely prevent electrolyte from leaking from the pole-column sealing portion, and reliability is particularly low in the negative pole. In addition, because the film is thin, even if a film with low water vapor permeability such as polyvinylidene chloride is used, dissipation of electrolyte from the film cannot be completely removed in high temperature and low humidity environments, resulting in shortened battery life. It had

The film in the center of the battery is an insulating layer 7 that does not contain lead film in order to maintain insulation between the anode plate 5 and the cathode plate 6. The electrode plate group had a scraped plate configuration using one anode plate 5 and one cathode plate 6. The pole pillar sealing part is, as shown in FIG.
Next, the lead film 1 in the center of the laminate film 4 and the solder portion 9 were connected and sealed around the pole pillar 8 with solder, and then an epoxy resin 10 was poured into the upper part. Furthermore, in order to complete thermal welding, chlorinated polypropylene was applied on top of the epoxy resin IO. Thereafter, the periphery of the laminate film 4 was heat-welded at a heat-welded part 11 as shown in FIG.
