等で被覆している。Sealed batteries whose openings are joined by welding in this manner suffer from welding defects due to pinholes, weld cracks, etc. in the welded portions. These defective batteries are either rejected or the defective welded part or the entire welded part is coated with @-based anticorrosion paint, polymeric gold powder paste 1 solder, phenol lv resin, epoxy resin, etc.

池を使用していると、ピンホーμや割れ等の溶接不良箇
所から電解液の漏出又はソρティングを生じる。These coatings are chemically corroded by alkaline electrolytes, have poor adhesion strength, and lack durability. Therefore, when a battery is used for a long period of time, electrolyte leakage or sooting occurs from welding defects such as pinholes and cracks.

ある。Purpose of the Invention The present invention has been made in view of the above-mentioned conventional problems.
The object of the present invention is to provide a rectangular sealed battery that is prevented from electrolyte leakage or sorting or from rusting at welded parts.

膜な溶着したことを特徴とする角形密閉電池である。Structure of the Invention The present invention achieves the above-mentioned objects by applying metal foil to the welded portion of a battery which is formed by sealing the opening of a metal rectangular tube or can with a metal lid plate and a metal bottom plate by welding. This is a prismatic sealed battery characterized by a membrane welded to the battery.
実施例 以下、本発明の詳細について夾施例により説明する。Example Hereinafter, the details of the present invention will be explained with reference to examples.

2 is a metal lid plate, 3 is a bottom plate S4 is a welded portion, 5 is a metal foil film, 6 is a positive electrode terminal, and 7 is an insulating plate.
金属製の角形缶(電槽缶)に極板及ひセバレータよりな
る発電要素を挿入し、金m製蓋板をはめ込む。A power generation element consisting of an electrode plate and a separator is inserted into a rectangular metal can (container can), and a lid plate made of gold is fitted.
次に電檜缶と萱板の間隙をレーザ溶接により接合する。Next, the gap between the electric cypress can and the thatch board is joined by laser welding.

も同様である。The width of the laser weld is approximately 0.5 m. An alkali-resistant metal foil film such as Nutenless foil or nickel foil is welded to the upper part of this welded portion with a thickness of 10 to 50 μm. The welding method may be laser welding or arc welding. The width of the metal foil film is 1 to 5-
That's fine. By welding the metal foil film, leakage and corrosion can be prevented.
- Rust no longer occurs. The same applies to the bottom plate.
発明の効果
上述した如く、本発明は電解液の漏液又はソμティング
あるいは溶接部の錆を防止した角形密閉電池を提供する
ことが出来るので、その工業的価値は極めて大である。Effects of the Invention As described above, the present invention can provide a rectangular sealed battery that prevents electrolyte leakage, sooting, or rusting of welded parts, and therefore has extremely great industrial value.
