Summary of the overall project:
The aim of the “HiStructures” project in the ProZell cluster is to significant increase the energy density of lithium-ion cells while simultaneously save material and manufacturing costs in order to create the conditions for a large-scale battery production in Germany. Within the framework of HiStructures, different process based structuring concepts as well as their combination with each other will be investigated (e.g. active material blends, gradient electrodes, multi-layer coating). In particular, the focus is on the combination of process-engineering and simulation. The simulations help to determine the optimal structure of the electrodes and, moreover, allow to identify and minimize loss mechanisms during battery operation. If successful, it would be possible to produce improved electrodes with a higher production throughput and thus lower costs. The further development of the processes up to a pilot scale will provide a comprehensive understanding of the process-structure-property relationships as well as the necessary know-how for a transfer to industrial production.
