The invention discloses a nitrogen or argon sealed storage device and method for a zinc silver battery. The nitrogen or argon sealed storage device for the zinc silver battery comprises a sealed storage device body and a vacuumizing gas path and inflation gas path. The sealed storage device body is used for being connected with a gas source, and nitrogen or argon serves as the gas source. The sealed storage device body comprises a first gas delivery pipeline. One end of the first gas delivery pipeline communicates with the gas source. A first water throttle valve, a second water throttle valve and a pressure gauge are installed on the first gas delivery pipeline. The vacuumizing gas path and inflation gas path comprises a second gas delivery pipeline, and one end of the second gas delivery pipeline is connected with a vacuum pump. A third water throttle valve, a fourth water throttle valve and a vacuum gauge are installed on the second gas delivery pipeline. The other end of the first gas delivery pipeline, the other end of the second gas delivery pipeline and the zinc silver battery communicate through a tee joint. By the adoption of the technical scheme, the purity of nitrogen or argon inside the zinc silver battery can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of reserve batteries and accumulators, in particular to a nitrogen or argon sealing device and method for a zinc-silver battery. Background technique [0002] Zinc-silver batteries are widely used in various fields due to their high specific energy, high specific power, large current discharge, stable discharge voltage, high voltage accuracy, reliability and safety. Zinc-silver batteries are generally composed of battery pack casings, sockets, gas generators, liquid reservoirs, combined plate sets, electric heaters and other components. Among them, the positive and negative electrodes inside the zinc-silver battery are completely isolated. When the battery pack is in use, turn on the external activation power supply to ignite the gas generator to generate sufficient pressure, inject the separately stored electrolyte into the combined plate group within the specified time, activate it to establish an electro...
