電池の改良に係り、封口蓋の集電端子部分の耐掲食性を
高めて長期使用に耐え得る密閉形電池を提供することを
目的とする。DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a sealed battery that can withstand long-term use by improving the corrosion resistance of the current collector terminal portion of the sealing lid.

端子部材としてのパイプまたはビンとをガラスで気密封
着した構成となっている。For example, in batteries such as thionyl chloride-lithium batteries that require a high degree of hermeticity, a hermetic seal is employed as a sealing means. In the case of this hermetic seal, the battery case and the sealing lid are joined by welding, and the sealing lid is made by hermetically sealing the annular body that also serves as one electrode terminal and the pipe or bottle that serves as the current collector terminal member with glass. The structure is as follows.

ガラス層の内部歪の発生が防止でき、かつ高い密閉性が
得られるからである。By the way, the body of the conventional sealing lid was made from SU in consideration of cost and resistance to the strong corrosive action of thionyl chloride.
A low carbon iron-chromium-nickel alloy such as S 804 L is used, and the glass has a thermal expansion coefficient of 90 to 120
10-7/'C soft glass is used, and the pipe or bottle is made of S, which has a coefficient of thermal expansion that is almost the same as that of the soft glass.
UR 446 was used. This is because if the thermal expansion coefficient of the pipe or bottle matches that of soft glass, there will be no big difference in the shrinkage rate due to cooling after sealing.
This is because generation of internal strain in the glass layer can be prevented and high sealing performance can be obtained.

耐え得る密閉形電池が得られるようにしたものである。In order to obtain a pipe-shaped tube by welding, it is necessary to cold-draw the seamless tube, making it a very expensive pipe material. The invention of wood was made in view of such circumstances, and the body of the sealing lid is made of an iron-chromium-nickel alloy, and the glass is made of a soft material with a coefficient of thermal expansion of 90 to 120X 10"-'/°C. By using glass and a low carbon 18 quarm iron alloy for the pipes or pins, the corrosion resistance of the current collector terminal member made of the pipes or pins is improved, and a sealed battery that can withstand long-term use is created. It was made so that it could be obtained.
