２と一体化して気密封口していた。Conventional technology Conventionally, in this type of battery, thionyl chloride, which is the active material for the positive electrode and the solvent for the electrolyte, is highly corrosive and also generates toxic gases, so the battery case has been required to have corrosion resistance and a high degree of airtightness. As required, as shown in FIG. 1, a battery case A1 made of corrosion-resistant stainless steel or nickel-plated steel and pins 3 serving as electrode terminals are hermetically sealed with a hermetic seal 4 made of glass or ceramic. After welding the battery case B2, the above-mentioned thionyl chloride is injected from the injection port provided at an arbitrary position of the battery case, and then a sealing plug 5 made of corrosion-resistant stainless steel or nickel is inserted. ,
Melt the head of the sealing plug by welding and attach it to battery case B.
It was integrated with 2 and sealed airtight.
