[PROBLEMS] To provide a high-capacity, safe, highly reliable, sealed heat-resistant, high-impact, sealed-type alkali that maintains the safety of the battery even when there is a sudden increase in internal pressure due to rapid charging. A storage battery, in particular a nickel metal hydride storage battery, is provided. A battery in which a battery case can is sealed with a lid body that interrupts energization when the internal pressure of the battery increases, the lid body having a sealing plate and a cap, and a cap provided with an exhaust hole. Is connected to a sealing plate to form an electrical terminal of one polarity, and in the cap, a strip 8 that is electrically insulated at least one of the upper and lower sides and an insulating seal around the upper surface without contact with the cap. The valve plate 9 is provided with a stop member, the valve plate is electrically connected to the electrode of the polarity, and the valve port provided on the sealing plate is pressed and closed by the ridge.
