PURPOSE:To obtain a thermal battery which provides a simplified structure, can be manufactured easily, does not provide short-circuit by fused negative pole and realizes discharge of a heavy current by surrounding a negative pole consisting of an active material which fuses at a battery activating temperature and a collector by means of an integrated layer of electrolyte-depolarizer made of the electolytic material, its absorbing agent and depolarizer and by sealing such negative pole within the ?-shaped positive pole collector. CONSTITUTION:An igniter 21 which generates an ignition signal to the igniter terminal 23 fires, each heating agent 20 burns simultaneously, momentarily heating an elementary cell 19. The heated elementary cells supply an electrical power through the process that the DBE layer 13 is heated through the positive collector 14, the contained electrolyte fuses and becomes conductive for ions and battery reaction is generated between the negative pole 11 and the depolarizer. since the negative pole is surrounded by the DEB layer, leaking flow of molten material can be prevented even when an alloy such as Li, Ca-Li2, Li-Mg, for example, which fuses at a temperature lower than the fusing point of electrolyte is used as the negative pole activating substance. |
