Abstract

The invention discloses a gas generator for a zinc-silver reserve battery and a preparation method of the gas generator, and belongs to the technical field of zinc-silver reserve batteries. The gas generator comprises a gas generating assembly, one end of the gas generating assembly is detachably connected with an ignition component, the other end of the gas generating assembly is provided with a gas guiding assembly, and the gas generating assembly is provided with a gas spraying hole communicated with the interior of the gas guiding assembly. The conductive column is connected with the short shell in a glass sealing mode, the sealing performance is good, the insulation performance of the conductive column is guaranteed, and the structural strength and the sealing performance of the gas generator can be improved. The mode that the pressing ring is in threaded connection with the short shell is adopted, the sealing film is pressed to seal the pyrotechnic composition, the structure is simple, operation is convenient and fast, the assembling technology is simplified, the threaded connection length can be adjusted according to the amount of the pyrotechnic composition through threaded connection sealing, and adaptability is high.

Description

technical field [0001] The invention relates to a gas generator for a zinc-silver reserve battery and a preparation method thereof, belonging to the technical field of zinc-silver reserve batteries. Background technique [0002] Zinc-silver storage battery is a chemical power source with high specific energy and specific power. Maintenance and other advantages, it has been widely used as a DC power supply in high-power devices. Gas generators have been widely used in the field of zinc-silver storage battery packs, for example, the Chinese patent literature with publication number CN109841860A discloses a parallel gas generator activation structure for zinc-silver storage batteries, and the Chinese patent literature with publication number CN108832151A Disclosed are an activation system and method for a zinc-silver reserve battery. When the battery is activated, sufficient pressure is generated by the gas generator, and the separately stored electrolyte is injected into the...
