14067/TUB: Method and Apparatus for Z-folding of Batteries
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.
The aim of the invention developed at TU Berlin is to provide a method and an apparatus for z-folding a separator material to enable a continuous folding with the highest possible t
hroughput. The approach pursued is the shifting from discrete pick-and-place operations to a continuous process flow, enabling a cost-efficient production of electrode-separator compounds and finally the production of lithium-ion batteries.
The concept represents a major step towards a competitive manufacturing process in the production of batteries.
