金属封口板で絶縁バッキングを介して金属容器の開口部
を内方へ折曲し、絶縁密封口していた。The conventional battery sealing method involves placing an anode mixture in a metal container that also serves as an anode terminal, an electrolyte consisting of caustic potash or caustic soda aqueous solution for alkaline batteries, propylene carbonate solvent for organic solvent batteries, gelled zinc, metallic lithium, etc. The opening of the metal container was bent inward through an insulating backing with a metal sealing plate that also served as a cathode terminal to form an insulating seal.

。However, with this type of conventional battery, during use or storage, the electrolyte leaks to the outside from the WR edge of the metal sealing plate, causing a short circuit in the battery and corrosion of external equipment using the battery. There were many accidents that caused the battery's discharge capacity to decrease.

する製造法があった。For this reason, insulating backings made of various materials have been considered in the past.Furthermore, an adhesive solution containing asphalt pitch or microcrystalline wax dissolved in a solvent has been applied to the surface, or the insulating backing has been immersed in the solution and attached. There was a manufacturing method in which a thin film of adhesive was formed by drying a solvent at high temperature, and the film was interposed between the periphery of the cathode sealing plate and the metal container to seal the container.
しかし、この製造法では接着剤で絶縁パブキングが互に

寄りが大きくなるため、薄い部分において亀裂が多く発
生した。However, in this manufacturing method, the insulating paperbacks are bonded to each other with adhesive, and when they are separated into individual backings, the adhesive layer partially peels off. Cracks occurred.This tendency was more common as the shape of the insulating backing was more complex, and in particular, as the local thickness of the adhesive layer became uneven, more cracks occurred in thin parts.
このためこのような接着剤層を有する絶縁バッキングを
用いて密封口した従来の電池は、密封効果が低く、漏液
藺止効果に不安定な欠点があった。For this reason, conventional batteries sealed using an insulating backing having such an adhesive layer have a drawback that the sealing effect is low and the leakage prevention effect is unstable.

た電池を提供するものである。In the present invention, an insulating backing whose surface is coated with a thermoplastic adhesive solution containing a pressure-sensitive adhesive is frozen and solidified at a low temperature, air-dried, and sealed with a sealing pressure of 1-5 Kp/1. By doing so, the above-mentioned conventional drawbacks are eliminated and a battery with excellent leakage resistance is provided.

て接着剤層２を形成する。In the figure, 1 is an insulating backing made of nylon 6 or nylon 66, etc., and this insulating backing 1 is immersed in a solvent solution of an alkali-resistant, thermoplastic, and pressure-sensitive adhesive dissolved in toluene, isopropyl alcohol, etc. Then, pull it up to make the surface of the insulating pubking l an adhesive solution layer, then leave it at -40°C for 5 minutes to freeze the adhesive solution layer and make the surface of the insulating pubking l non-tacky. was air-dried for 1 hour under a humid condition at 50° C. to form adhesive layer 2.

化でき、より優れた密封状態を作り出せる。In the present invention, an adhesive solution layer is formed on the surface of the insulating backing, and this is subjected to freezing air-drying treatment in a low-temperature chamber. Therefore, in the adhesive layer 2, only the solvent on the surface dries, and the inside has an unevaporated solution layer. As a result, fine racks will not occur in the adhesive layer 2, and since the adhesive layer 2 is used to seal the opening, the unsmoked adhesive solution layer will be removed when the forceps are pressed. It is infiltrated and filled into the periphery of the separator 4, the metal sealing plate 8, or the minute gap with the metal container 6, thereby ensuring sufficient sealing. In addition, since pressure-sensitive adhesive is used, 1 to SKI/d
Since the seal is sealed with a pressure of , the adhesive sealing property is increased, and furthermore, the bottom surface of the insulating backing 1 and the periphery of the separator can be adhesively integrated, and a more excellent sealing state can be created.

である。In terms of mass production, the surface of the adhesive solution layer can be dried instantly by air-drying the adhesive solution layer using a freezer.
The backings do not stick to each other, and a large amount of insulating backing can be processed at once without any trouble. Handling is extremely simple, and the workability of battery assembly can be greatly improved.
