産業上の利用分野
本発明は、有機電解液系のリチウム電池、アルカリ電解
液系の酸化銀電池、水銀電池、アルカリマンガン電池、
及び空気亜鉛電池等の密閉電池の封口部の改良に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to organic electrolyte-based lithium batteries, alkaline electrolyte-based silver oxide batteries, mercury batteries, alkaline manganese batteries,
The present invention also relates to improvements in the sealing part of sealed batteries such as zinc-air batteries.
従来例の構成とその問題点
この種密閉電池の絶縁バッキングは、（１）有機電解液

う、耐薬品性の強い樹脂により形成２ぺ−３
すること、（２）密閉効果が高く、機械的強度の強い樹
脂により形成することが、必要条件とされている。Structure of conventional examples and their problems The insulating backing of this type of sealed battery must (1) be made of resin with strong chemical resistance so as not to be decomposed by electrolytes such as organic electrolytes or alkaline electrolytes; , (2) It is a necessary condition that it be formed of a resin that has a high sealing effect and strong mechanical strength.

で、絶縁バッキングは、密度の低い状態で存在しており
、従って電池の耐漏液性能が低下し、それがため電池特
性の劣化を生じさせるという欠点があった。Conventional insulating backings for sealed batteries fully satisfy (1) chemical resistance, but do not fully satisfy (2) mechanical strength, and when the battery is sealed, the battery case and sealing plate The insulation backing protrudes from between the battery case and the sealing plate, and the insulating backing exists in a low density state between the battery case and the sealing plate, which reduces the leakage resistance of the battery, which affects the battery characteristics. It has the disadvantage of causing deterioration.

たバッキングである。Figure 1 shows an example of a conventional organic electrolyte-based lithium battery. 1 is a battery case made of stainless steel, 2 is a sealing plate made of the same material, and 3 is a grid bonded to the inner surface of the sealing plate. 5, and a negative electrode lithium sheet 4 is pressure-bonded to this surface.5
The positive electrode is a disk-shaped mixture of 100 parts by weight of fluorinated graphite, 10 parts by weight of acetylene black as a conductive material, and 5 parts by weight of SBR as a binder, and is in contact with a titanium grid 6 welded to the inner surface of the case. are doing. 7 is 37

ため電池特性の劣化を生じさせるという欠点があった。Polypropylene has relatively good impact resistance, but
If a backing made of polypropylene is used because its tensile yield point stress is low, the backing will protrude from between the battery case 1 and the sealing plate 20 at the time of battery expiry, and the backing will be damaged between the battery case 1 and the sealing plate 2. The stable existed in a low state. Therefore, there has been a drawback that the leakage resistance of the battery is lowered, resulting in deterioration of battery characteristics.
発明の目的
本発明は、上記のような欠点を解消し、絶縁バッキング

の向」二をはかることができる。According to this configuration, since the mechanical strength of the rising part of the insulating sealing donkey king is strong, it is possible to prevent the insulating backing from protruding from between the battery case and the sealing plate when the battery is due, and the battery case and the sealing plate can be prevented from protruding. It is possible to interpose a high-density insulating backing between the batten and the batten. Therefore, the insulating backing made of resin with high electrolyte resistance in the brim can also be interposed in a high-density manner between the battery case and the sealing plate. As a result, the leakage resistance performance of the battery can be improved.
