FAQs
Why weld instead of solder pouch tabs?
Solder heat would damage the pouch seal and the separator; ultrasonic welding keeps the tab cool while still making a solid joint.
How many foil layers does it bond?
The head is sized to the tab, and all layers of the foil stack are consolidated in one cycle.
Is flux used inside the cell?
No — and none should be, since any residue would contaminate the cell chemistry.
