Embodiment Construction

[0013] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0014] The accompanying drawing is a structural diagram of the pole sealing device of the hydrogen-nickel storage battery of the present invention. As shown in the figure, the device includes: outside the pole 7, a nut 1 with a circular structure, a dish washer 2, a ceramic washer A3, a seal 4, a pole sleeve 5, and a ceramic washer B are sequentially sleeved from top to bottom 6. The above-mentioned pole 7 , ceramic washer B 6 and seal 4 are inserted from the inside of the pole sleeve 5 . A ceramic washer A 3 is put on the periphery of the pole sleeve 5, and is tightened by the nut 1 and the dish washer 2 to form a seal. The above-mentioned parts are combined into a pressure-resistant and corrosion-resistant sealing structure. The pole sleeve 5 is integrated with the battery case by vacuum electron beam welding. The pole sleeve 5 and the pole 7 are...

Abstract

The invention relates to a pole sealing device for a MH / Ni battery, comprising a pole (7). A nut (1), a disc gasket (2) coated by round structures in turn from top down, a ceramic gasket A (3), a sealing member (4), a pole sleeve (5), a ceramic gasket B (6) are coated on the surface of the pole (7). The pole (7), the ceramic gasket B (6) and the sealing member (4) are inserted into the pole sleeve (5) through the sealing member (4); the ceramic gasket A (3) is coated on the periphery of the pole sleeve (5), and fastened by the nut (1) and the disc gasket (2); the pole sleeve (5) is integrated with the battery shell by vacuum electron-beam welding. The invention settles the problem of pole sealing of MH / Ni batteries, and has the advantages of simple process, easy assembly, low cost and sound sealing performance, etc.

Description

technical field [0001] The invention relates to a space vehicle power supply, in particular to a pole sealing device for a nickel-hydrogen storage battery. Background technique [0002] As an energy storage power supply, the nickel-hydrogen battery is an important part of the satellite's primary power supply subsystem. It will undertake the task of supplying power to the entire satellite during the active flight after the satellite is switched from the internal power supply and during the earth shadow period. The only source of energy is the core factor that determines the on-orbit working life of the primary power supply. Therefore, the energy storage power supply must be highly reliable in order to meet the power supply requirements during the entire satellite launch and on-orbit operation. [0003] The nickel-hydrogen battery is the product of the combination of nickel-cadmium battery technology and fuel cell technology. The positive electrode comes from the nickel oxide...
