Second Webinar of the Battery2030+ Series Explores Advanced X-ray Interface Studies
The first webinar of the new series “Time and Length-Scale Operando Bridging Techniques to Study Battery Interfaces” took place on 20 November 2025, bringing together researchers interested in advanced operando characterisation of battery materials.
The webinar series is jointly organised by our project, OPERA, and ULTRABAT within the Battery2030+ initiative.
The goal is simple but ambitious — to help scientists see inside batteries while they work.
Understanding Battery Interfaces Across Scales
Battery interfaces are critical regions where electrochemical reactions occur and strongly influence battery performance, lifetime, and safety. Observing these interfaces during operation remains a major challenge in materials science. Operando X-ray techniques help address this challenge by revealing how structural and chemical changes evolve across different time and length scales.
As in previous sessions, the webinar combined a short methodological introduction with a research-focused presentation, encouraging discussion and knowledge exchange across disciplines.
Advanced X-ray Methods for Battery Interface Research
The session featured Prof. Hans-Georg Steinrück (Forschungszentrum Jülich, Germany), who presented “Surface-Sensitive and Coherent X-ray Methods to Study Battery Materials.” His talk highlighted how advanced X-ray techniques provide insight into the evolution of battery materials, from atomic-scale surfaces to complex mesoscale interfaces.
The webinar underlined the importance of combining complementary operando methods to better understand interfacial processes and support the development of longer-lasting and safer batteries.
