|description===Production process==

*During the stacking process the separated electrode sheets are stacked in a repeating cycle of anode, separator, cathode, separator, etc.
*A wide variety of stacking technologies exist, which are usually patented by specific manufacturers.
*A classic variant of stacking is the so-called Z-folding.
*The anode and cathode sheets are inserted alternately from the left and right into the z-shaped folded separator. The separator is used in the form of an endless tape and is cut off after the * stacking process.
*The cell stack is finally fixed with adhesive tape.
*The exact positioning of the individual sheets is considered as the central quality criterion.
*The sheets are usually transported and positioned by vacuum grippers.
*Depending on the cell specification, a cell stack can consist of up to 120 individual layers.

==Process parameters & requirements==

*Z-folding: Individual anode and cathode sheets are placed laterally in the Z-folded separator web
*Single-sheet stacking: Separator is available as a sheet for stack formation
*Stacking accuracy: ± 200 μm - 300 μm
*Z-folding and single-sheet stacking : cycle times of 1 s/sheet

==Technology alternatives==

*Lamination process: The individual electrode and separator sheets are laminated onto each other in a continuous process and are then usually pressed together by a heat press.
*Pocket Stacking: The cathode sheets are placed in a separator pocket. Afterwards cathode and anode sheets are stacked alternately.

==Quality influences==

*Position detection and alignment of sheets of different sizes with a vacuum gripper
*Mechanical pre-tensioning of the separator

==Quality features==

*Positioning accuracy of the anode and cathode sheets
*Damage-free electrode surfaces and edges
*Avoidance of electrostatic charging
