The application of energy storage systems in aviation demands high energy and power density. One of the most promising battery technologies with the potential to satisfy this demand is the all-solid-state lithium-sulfur battery. However, the performance (energy and power density) of currently developed cells is far from its theoretical capacity and not sufficient for aviation yet. The necessary enhancements in performance can only be achieved with a profound understanding of the promising materials and their capabilty of combination. Additionally, the influence of their micro- and macro-structure on electrochemical properties has to be investigated. Therefore, this project focuses on gaining a multi-scale understanding at the level of the surface, electrode and cell. This requires both, experimental and model-based approaches. In detail, experimental work on specific design and the processing-influence on the resulting performance must be coupled with structural and kinetic modeling of the processes, structures and interfaces in the electrodes.
