Example Embodiment
[0022] Example 1
[0023] (1) Put the soft-packed battery cell to be injected into the clamp between the two splints, vacuum and inject the required amount of electrolyte, the clamping pressure of the splint is 0.05MPa, and the vacuum degree of the first vacuum is -0.085Mpa;
[0024] (2) Put the soft-packed battery cell at 20℃ for 6h;
[0025] (3) Rolling the front and back of the soft package cell to drive the gas to the side of the airbag, and cut the opening on the side of the airbag to exhaust, the rolling pressure is controlled at 0.1MPa, and the front and back of the soft package cell are rolled once;
[0026] (4) Put the soft-packed battery cell between the two splints, clamp and fix it, vacuumize the battery cell for the second time, then fill it with dry air and hold the pressure, after completing the second vacuuming and proceed For sealing, the clamping pressure of the splint is 0.15Mpa, the vacuum degree of the second vacuuming and the third vacuuming are both -0.085Mpa, ...
