Abstract The use of novel battery technologies in short‐haul electric aircraft can support the aviation sector achieving its goals for a sustainable development. However, production batteries is often associated with adverse environmental and socio‐economic impacts, potentially leading to burden shifting. Therefore, this paper investigates alternative lithium–sulfur all‐solid‐state (LiS‐ASSBs) terms their contribution development (SDGs). We propose new approach that builds on life cycle sustainability assessment links relevant impact categories related SDGs. applied analyze four LiS‐ASSB configurations different solid electrolytes, designed maximum specific energy using an electrochemical model. They are compared liquid electrolyte as benchmark. results our cradle‐to‐gate analysis reveal generally have positive SDG achievement. configuration best technical characteristics not most promising Especially variations from technically optimal cathode thickness improve contribution. A sensitivity shows rather robust against weighting factors within quantification method.
