PURPOSE: To get a battery highly reliable on the operation of explosionproof function by providing a thin part at the bottom of a battery container, using oxyhalide of liquid for a positive active material, and alkaline metal or its alloy for a negative pole.
CONSTITUTION: A compound 14 being liquid at normal temperature such as thionyl chloride, sulfuryl chloride, phospholi chloride, etc., is used for a positive active material. Li, Na, K, or alloy having these materials for its base material is used for a negative electrode. A thin part 4 is provided at the bottom 2 of a battery container 1. A wire gauze or a porous substance 5 of metal such as an expand metal, punching metal, etc., is arranged at the inside of the bottom, and the periphery is spot-welded to the inside of the bottom 2 of the container 1. The thin part breaks by the abnormal rise of the inner pressure of a battery, which prevents the bursting under high pressure.
