AKE technologies GmbH is working together with the Technologiezentrum Energie (TZE) of the University of Landshut on a research project to improve the performance of batteries. The aim of the SpinnAP (Spinning Technologies for Advanced Battery Production) project is the production of long-lasting and reliable batteries.
The electrospinning process used is faster and more productive than the existing processes and can be easily integrated into existing production lines. In electrospinning, materials are spun into the finest fibers with diameters of a few micrometers or nanometers. These nanofibers optimize the performance in energy storage and lead to the improvement of rechargeable lithium cells. For the current project progress, the first spinnable recipes have already been developed and built into cells.
As part of the project, research is also being carried out into the method of lamination of electrodes - a process that was previously not possible. This technique contributes to the faster production of batteries and increases productivity when building particularly long-life lithium-ion cells. AKE technologies is developing the lamination system for this. The process is continuously optimized in numerous development and test loops together with the TZE in order to make cell production as efficient as possible. In a first proof-of-concept attempt, fibres were spun on a separator – this modified separator was then successfully laminated. In addition, the researchers have already succeeded in defining parameters and a suitable process environment for successful lamination.
Working together with the TZE, we not only want to improve the manufacturing process, but also the longevity and range of battery cells. Our goal is to contribute our share to make e-mobility more attractive for the general public and to establish it as the optimal solution for industry and private households.
