Abstract: The present invention relates to an ampoule-type storage battery and, more specifically, to an ampoule-type storage battery capable of extending life by preventing leakage of an electrolyte. According to the present invention, the ampoule-type storage battery comprises an ampoule means. The ampoule means includes: an ampoule casing having a receiving part formed therein; an electrolyte received in the lower part of the receiving part; an anti-leakage liquid formed of oil, which does not mix with the electrolyte and is phase-separated, contained in the upper part of the receiving part to prevent the electrolyte from leaking through the upper part of the receiving part; and a membrane mounted on the receiving part to separate the electrolyte and the anti-leakage liquid. Accordingly, the electrolyte is received in the lower part of the ampoule casing and the anti-leakage liquid is received in the upper part of the ampoule casing. Since the anti-leakage liquid is made of oil which does not mix with the electrolyte and is phase-separated, it is prevented that the electrolyte is leaked through the upper part of the ampoule casing, and thus the storage battery can be stored and used for a long time. In addition, a percussion pin has a groove formed at one end in the longitudinal direction so that the electrolyte received in the ampoule casing can flow to an absorption part when the ampoule casing is hit and broken, so that the electrolyte can be sufficiently permeated into the absorption part along the groove.
