Abstract

The invention provides a method for compressing and sealing the pole of a storage battery for use in space, which is characterized in that it includes the following steps: S1, assembling and fixing the sealing device: pressing the compression seal with a nut threaded on the outer wall of the pole, and pressing the pole The non-threaded end of the column is fixed on the fixed seat; S2, set torque: set the torque according to the pole material and pole diameter, and the size of the torque should not cause deformation or breakage of the pole and other components; S3, press at room temperature ; S4, high and low temperature alternating compression; S5, repeat step S4, until the torque set in step S2 cannot turn the nut after high and low temperature maintenance. The invention provides a method for compressing and sealing battery poles used in space. The battery can still have excellent sealing performance after being subjected to various temperature changes in the space.

Description

technical field [0001] The invention relates to the field of space vehicle energy storage power supply, in particular to a method for compressing and sealing battery poles used in space. Background technique [0002] The storage battery for space is a fully sealed chemical energy storage power supply, and the sealing performance is one of the very important factors that restrict and affect the performance and life of the battery. If the sealing performance is not good, the electrolyte and gas inside the battery will be generated Leakage, this will not only cause the electrolyte to dry up, the battery will fail, and endanger the safety of satellite power supply, but also the leaked electrolyte and gas will pollute the entire star environment and cause damage to surrounding products. [0003] Space batteries work in a high-vacuum environment and have a long working life (the life of high-orbit batteries is 15a-20a, and the life of low-orbit batteries is 5a-8a), which puts forw...
