Summary

In this episode of the Geladen podcast, hosts Daniel Messling and Patrick von Rosen interview Dr. Martin Etter from DESY and Dr. Fabian Jeschull from KIT about the challenges of battery research and how synchrotron radiation helps overcome them. The discussion begins with the difficulty of studying batteries as closed systems, requiring inert gas handling and complex operando measurements. Dr. Etter explains what synchrotron radiation is, comparing it to bremsstrahlung used in medical X-rays, and describes the PETRA III facility at DESY, including its storage ring, magnets, and undulators that produce intense X-ray beams. Dr. Jeschull highlights key unresolved questions in lithium-ion battery research, such as oxygen evolution in NMC cathodes and the need for long-term data and reproducibility. The episode also covers the engineering effort behind such large-scale facilities, with about 3000 people working on the DESY campus. A sponsorship segment for Spherity’s digital product passport is included, which is clearly separated from the scientific content.
