Z-folding

Battery cells can be produced in stacking or winding processes, or using hybrid techniques such as the Z-folding process.

In Z-folding, individual electrode sheets are inserted into a folded separator film. First, an electrode sheet is placed on the separator film. Next, the separator is folded over the electrode sheet, allowing a sheet of the other electrode to then be placed on the separator. This process is repeated multiple times.
