Battery cell production for E-Mobility
After filling the battery cell with the electrolyte, the filling opening is closed with a cover and tightly welded with laser light. This seals the cell and prevents the electrolyte from escaping. The cell is thus sealed. The welding of battery cells is a critical process step, as it is a tightness welding. If the cell is leaky, it is scrap.
