Key process steps process steps for Cell Manufacturing

Degassing and Final Sealing

After Pre-Charge, the cells will be finally degassed, cleaned and sealed for further processing. An endcap will be laser welded over the filling hole, providing a clean and reliable closure of the cell.

The machine is also part of the Cell Finishing Line, using a micro-dry environment inside the machine. This way we avoid the complex logistics of moving pallets between the main dry room and formation area.

PEC’s proprietary laser welding technology provides minimum energy to the weld pool, reducing the area affected by heat.

Benefits:

• No complex logistics between Cell Formation Area and Dry Room
• Huge savings in energy due to micro-dry environment
• Better and more reliable seal
• Integrated cleaning process
