Notes:
Airtightness must be tested — Take 3 PCS sealed shell spaces and pressurize on the testing machine; maintain at ≥1 MPa for 1 minute; no gas leakage on the four sealing walls is considered qualified.
For each shift, randomly inspect one cell by disassembly and confirm that the cover plate deformation is ≤0.3 mm.
