Method and Apparatus for Z-folding of Batteries

Ref-Nr: TA-14067/TUB


Kurzfassung

For a cost-efficient production of battery systems, a high degree of automation as well as an increased production throughput are necessary. This method offers a possibility to significantly increase the production throughput using the so called z-folding of separators. Thus we are shifting from discrete pick-and-place operations to a continuous process flow, enabling a cost-efficient production of electrode-separator compounds and ultimately lithium-ion batteries. 


Hintergrund

The electrification of drives is an enormous challenge as well as an opportunity for the automobile industry and its suppliers to provide competitive and affordable technologies to participate within this technology change. The high costs of battery systems, the limitations of the range of electric vehicles and the presently insufficient charging network are three of the main reasons, why the realization of this change is still troublesome. To realize a cost-efficient production of battery systems, a high degree of automation and an increased production throughput is necessary. Current handling methods are characterized by pick-and-place operations. Their productivity is limited by necessary sequential setting and resetting movements.
