を特徴とする′防爆型電池。A dish-shaped terminal plate that also serves as a lid of the battery case, a gas vent hole formed in this terminal plate, and a diaphragm-shaped thin plate provided inside the terminal plate so as to seal the concave space;
The terminal board has a cutting edge-like protrusion whose tip is opposed to the center of the outer surface of the thin plate, and when the gas pressure inside the battery case increases beyond a predetermined level, the terminal board receives the gas pressure. In an explosion-proof battery in which the thin plate is broken by the protrusion and gas is safely released from the gas vent hole, the thin plate abuts the tip of the protrusion in a normal state,
An explosion-proof battery characterized in that the thin plate is bent by contact pressure with the protrusion.
