Background
The thermal battery is a thermal-activated battery which can be discharged in extreme environments and has high specific energy, and is widely applied to the fields of military, space exploration, underground mining industry and the like. The pyrotechnic system inside the thermal battery is ignited by means of electric activation or mechanical activation, and then the igniting strip ignites the heating material to release heat. In seconds or even tens of milliseconds, the internal temperature of the battery rises rapidly, the molten salt electrolyte in the solid state melts rapidly, and the battery begins to discharge. The effective working temperature range of the thermal battery is 450-550 ℃.
Typically, the heating material in the thermal battery, once ignited, can release a large amount of heat in a few seconds, the temperature inside the thermal battery rapidly rises, and a large amount of gas is generated. The gas is accumulated in a large quantity, so that the internal gas pressure of the battery is gradually increased, and when the internal gas pressure of the battery exceeds the critical gas pressure value borne by the cylinder, the cylinder is fused and exploded, and serious potential safety hazards exist.
The patent with publication number CN216085007U can regularly remove the atmosphere inside the thermal battery shell through the air suction valve on the thermal battery, improves the storage life of the thermal battery, reduces the internal air pressure of the thermal battery shell, but the scheme has a complex structure.
