In the cell production laboratory, industrial cells in pouch format from 30 mAh to 2 Ah can be produced by hand. A manual sample line is available for the production of lithium-ion cells as single or bicells. The cell composite is assembled using free stacking, roll lamination or, if required, Z-folding.
As part of the CompStor project, semi-automatic partial production stations for trimming and arrester welding, housing sealing, electrolyte filling, degassing and finalisation as well as a database system for digitalisation were added.
In conjunction with the resources of the electrode production/cell testing/analytics laboratories, comprehensive material and process analyses can be carried out on various components of lithium-ion cells.
