Title: Sealed storage battery
Inventor: TSUBUKI AKIHIRO
IPC: H01M2/12
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To stably prevent an entrance of outside air when battery internal pressure is lower than outside air pressure, and to stably blow off inside gas when the internal pressure increases by a specific value or more by fitting an annular ring-shaped rubber member to a groove carved on the periphery of an exhaust cylinder outer wall part formed on a battery jar cover, and putting a hat-like reseal valve on an exhaust cylinder so as to cover the rubber member. SOLUTION: A cross-sectional V-shaped groove is carved on the periphery of an outer wall part of an exhaust cylinder 2 on a cover 1 of a battery. An O ring is fitted to this groove as an annular ring-shaped rubber member 4, and a reseal valve 5 is put so as to cover the rubber member 4 so that the upper surface is pressed down by a reseal valve presser 6. Thus, the O ring and an inner wall of the reseal valve 5 tightly contact with each other to secure sealing performance of the reseal valve 5 to thereby preclude the possibility of reducing battery capacity since a cathode active material is oxidized by oxygen in the atmosphere when outside air enters when battery internal pressure is lower than outside air pressure, so that an electrolyte hardly flows outside even when the internal pressure is higher than the outside air pressure.
