Abstract. The decarbonization of the civil aviation sector is a challenging task which relies heavily on electrification. Independent of the concept and amount of electrification, e.g. more electric aircrafts (MEA) or even fully electric propulsion systems, the battery plays an important role. The latter are often criticized to be immature in terms of gravimetric energy density. But even if a high-energy cell with a value exceeding 750 Wh/kg on the pack level would be available [1], it is not guaranteed to fulfill corresponding power requirements. Batteries suffer from an energy-power-dilemma and, hence, call for design and optimization of the electrode structure. Inspired by the success of scale-resolved simulations for design and optimization in conventional jet engines, we present a scale-resolved methodology for batteries. The toolbox’ potential to increase battery performance is showcased for a Lithium-Sulfur cell. The aforementioned chemistry is broadly anticipated as promising candidate for aerospace applications due to the exceptional high gravimetric energy density.
