Embodiment Construction
[0022] The method of the invention simulates the state of the pole group in the battery, and measures the pressure change of the pole group in a dry state and a wet state (after adding acid). see figure 1 , The required test equipment includes a tensile testing machine 1, a test briquetting block 2, a test container 5, an upper backing plate 3, and a lower backing plate 8. The area of the test pressing block, the cross-sectional area of the test container, and the area of the upper and lower backing plates need to be larger than the surface area of the tested pole group. The test container 5 is a flat-bottomed plastic shell, the bottom of the test container is provided with an acid discharge pipeline 6, and an acid discharge valve 7 is provided at the acid discharge pipeline.
[0023] still refer to figure 1 , the method of the present invention is described in detail below in conjunction with a specific embodiment:
[0024] (1) Prepare the test briquette, wrap the ...
