Next-generation solid-state batteries (SSBs) have the potential to transform the field of electromobility, offering enhanced safety and increased energy density. However, the successful realisation of this potential is contingent upon a more profound comprehension of the redox reactions occurring within SSBs. This enhanced knowledge is imperative for enhancing the cyclability of these batteries. The present project aims to develop an operando setup utilising wide-angle X-ray scattering (WAXS) for real-time analysis of these reactions during battery cycling under laboratory conditions.The project will utilise state-of-the-art high-brilliance laboratory microfocus X-ray sources (Ag Ka) and CdTe 2D X-ray detectors. These experiments will be performed in collaboration with the HORIZON EU projects, OPERA and SEATBELT, thereby guaranteeing involvement in a highly motivated international research team.
