description PURPOSE:To open a safety valve after current is shut off. CONSTITUTION:The safety valve of a sealed battery is provided with a conductive valve body 2 which is deformed when the pressure in the battery is increased, and an elastic thin plate 2A, which is broken to open the valve when a predetermined level of pressure is attained. The elastic thin plate 2A is pressed and broken by the gas in the battery that passes the valve body 2. The valve body 2 is connected to an intermediate connection body under a condition that the opening part of an outer packaging can 10 is closed. When the inner pressure of the battery is increased, the valve body 2 is separated from the intermediate connection body, and a part of the valve body 2 is broken, and the elastic thin plate 2A is pressed and broken by the gas in the battery that passes the broken opening part, The gas does not pass the valve body until the valve body is broken. The elastic thin plate is broken by the gas in an electrode, which penetrates the broken valve body. A safety valve is thus opened after current is shut off.
