PROBLEM TO BE SOLVED: To provide a sealed alkaline storage battery, especially a sealed nickel hydride storage battery, quickly recovering airtightness, of high capacity, safe, of high reliability, and of low cost, with safety of the battery not affected even by a rapid rise of inner pressure due to quick charging. SOLUTION: Of the battery with its battery can 1 sealed with a lid body 3 interrupting electricity at rise of the inner pressure of the battery, the lid body 3 is composed of a sealing plate 4 and a cap 5, of which the latter 5, provided with an exhaust hole 51, constitutes an electric terminal of one polarity in jointing with the sealing plate 4, and an elastic body 8 stored in the cap presses a valve plate 9 electrically connected to an electrode of the above polarity down to a valve hole fitted at the sealed plate 4 to close it. The elastic body is of rubber, and this rubber elastic body seals the exhaust hole 51 at normal times. COPYRIGHT: (C)2005,JPO&NCIPI
