2.1 Electrode Separating (Pouch/Prismatic)

Separating is the process of cutting electrode sheets from a continuous roll, to prepare components for stacking stage. Before separation, a notching step may be performed—where the anode or cathode electrode rolls are unwound and pre-shaped to define the contour and tab position. The anode and cathode are typically cut into discrete sheets using mechanical stamping or laser cutting. These sheets may be stored temporarily or directly passed to the stacking process. 

In cylindrical cell production the electrode and separator rolls are pre slit into long narrow stripes and are separated during the winding process.
