Laser cutting

Cutting electrodes with a pulsed laser instead of a die, used for notching and for separating sheets. It changes shape without a new tool, at the cost of a heat-affected zone that must be kept small.

Slitting

Cutting the wide coated roll into the narrow strips a cell needs, with rotary knives. A clean edge matters: burrs can pierce the separator and cause an internal short.

Stacking

Building a cell from individual electrode sheets interleaved with separator, either sheet by sheet or by folding a continuous separator in a zigzag. It uses the volume of a rectangular case better than winding but is slower and more exacting.

Tab

The strip of metal that connects an electrode’s foil to the cell terminal: nickel or copper on the negative side, aluminium on the positive. Tab count and width set much of a cell’s resistance and heat generation.
