It is characterized in that the gap in the battery sealing part is sealed with a sealing material made of a polymer mainly containing zero isobutylene.
以下、本発明を添付図面に基づいてさらに詳しく説明す
る。Hereinafter, the present invention will be explained in more detail based on the accompanying drawings.
第１図は本発明の一実施例に係る電池の封口部を示す。FIG. 1 shows a sealed portion of a battery according to an embodiment of the present invention.

同様に、ガスケット２および封口板３により電池ケース
１の開口部を封口している。In the battery shown in the figure, a power generating element with a nickel hydroxide anode and a cadmium cathode is housed in a battery case 1 which also serves as an iron cathode terminal, and an appropriate amount of electrolyte consisting of a 30% potassium hydroxide aqueous solution is injected. ing. As with a normal battery, the opening of the battery case 1 is sealed with a gasket 2 and a sealing plate 3.

できる。A sealing material 4, which is a feature of the present invention, is sealed in a gap 5 in a sealing part of a battery. Since the sealing material 4 has appropriate fluidity, the gap 5 can be sealed by any filling method such as coating, dipping, brushing, or injection.
なお、本発明の利口部の間隙には、場合により封口板３
と電極（図示せず）との間隙も含まれる。In addition, a sealing plate 3 may be used in the gap between the clever parts of the present invention.
This also includes the gap between the electrode and the electrode (not shown).

難となるので好ましくない。The sealing material 4 is a polymer formed by polymerizing isobutylene as a main monomer, such as an isobutylene homopolymer or a copolymer of isobutylene and n-butene. These are easily available under the trade names of Nippon Petrochemicals Co., Ltd., such as 8-stone polybutene and Tehlux. Moreover, the average molecular weight thereof is preferably 700 to 10,000. If it is less than 700, the sealing performance is insufficient due to low viscosity. Moreover, if the average molecular weight exceeds 10.000, the viscosity becomes too high and handling operations such as coating become a national problem, which is not preferable.

る。The wax used in the present invention includes animal and vegetable waxes, but preferably includes hydrocarbon waxes such as paraffin wax, microcrystalline wax, polyethylene wax, and atactic polypropylene (APP) wax. Particularly preferred is paraffin wax. For example, paraffin wax is obtained by dewaxing a petroleum distillate. Moreover, polyethylene wax is obtained as a by-product that is a low molecular weight component during polyethylene production. Further, APP wax is obtained as a by-product during the production of polypropylene resin.
