An explosion-proof sealing structure for a battery, wherein the sealing gasket is compressed between the composite lid and the outer periphery of the composite lid, the composite lid having the following configurations a to g. (a) The above-mentioned composite lid has a structure in which a flexible diaphragm plate and an airtight sheet are overlapped and held at the outermost periphery of a metal inner lid plate, and this is further combined with a terminal plate. (b) The diaphragm plate has a spacer in the center that is convex outward, and has an outer peripheral rib in the outer periphery that is convex outward, and the part between the spacer and the outer rib is It is a thin pressure sensitive part. (c) The inner cover plate has a rising portion formed by bending the outer periphery upward, and a pressure guiding hole is formed in the flat plate portion. (d) The rising portion of the inner cover plate is curled inward, and the outer circumferential rib of the diaphragm plate is hugged by the caulked portion. (e) The terminal board has a central convex part whose central part becomes convex outward, and a cutting edge with a gas vent hole is provided on the outer circumferential side of the central convex part, protruding toward the inner surface. There is. (f) A thin ring-shaped overcurrent is formed between the top of the caulked rising part of the inner cover plate and the bottom of the outer periphery of the terminal plate, which is made of a conductive polymer whose resistance value increases rapidly as the temperature rises. The protection element is held under pressure. (g) The tip of the cutting edge of the terminal plate is opposed to the pressure sensitive part of the diaphragm plate, and the tip of the spacer of the diaphragm plate is opposed to the inner surface of the central convex part of the terminal plate. ing.
