PROBLEM TO BE SOLVED: To provide a sealing plate for sealed electrochemical devices capable of rapidly discharging the gas accumulated in the devices to the outside by an explosion-proof valve that breaks at once in a bursting manner in order to prevent the explosion and inflammation of the devices, when the internal pressure of the sealed electrochemical devices such as capacitors and lithium batteries having electrolyte rapidly increases due to the gas accumulated inside the devices.SOLUTION: Disclosed is a sealing plate for sealed electrochemical devices, the plate comprising: holes 8, 81, and 82 for discharging gas; and an explosion-proof valve including valve membranes 7, 71, 72, and 73 made of a molded thermosetting resin for sealing the holes 8, 81, and 82 for discharging the gas. |
