The 42nd Seminar of Advanced Materials Center
We warmly invite you to the 42nd seminar of the Advanced Materials Center, which will take place on May 6th, 2026 (Wednesday) at 1:15 p.m. in NE 140 (building 42, WETI B).
Dr. Fabian Jeschull, Karlsruhe Institute of Technology (KIT) The Institute for Applied Materials – Energy Storage Systems (IAM-ESS), Germany, will present a talk entitled "Tends in post-lihium batteries".
Dr. Fabian Jeschull is a researcher specializing in electrochemistry and advanced energy storage technologies. He earned his Bachelor’s degree from the University of Konstanz and completed his Master’s and PhD at Uppsala University in Sweden. His research focuses on post-lithium battery systems, including sodium-ion, potassium-ion, and solid-state batteries, with particular expertise in electrolyte design and electrode–electrolyte interfaces.
Since 2022, he has been a Team Leader at the Karlsruhe Institute of Technology, where he leads a research group and manages laboratory activities. He is also a member of the Post-Lithium Cluster of Excellence (POLiS), where he serves as a research unit speaker for cross-sectional activities and as work-package leader for high-energy-density potassium-ion batteries. He is actively involved in European research initiatives and is recognized internationally for his scientific contributions, with around 50 publications and significant citation impact.
After the seminar, we traditionally invite you for pizza!

Abstract:
Beyond the conventional lithium battery technologies, new cell types are emerging to complement the existing battery portfolio. These cell chemistries, based on metal cations mostly from the alkali and alkaline-earth group, can address a number of unresolved issues that arise from the use of lithium-ion batteries. This includes the use of abundant and non-critical raw materials. For example, one of the aims is to replace cobalt by iron or lithium by sodium. This renders post-Li batteries potentially cheaper and more scalable, for example in grid storage applications, that will exceed the today’s demand of automotive batteries manifold.
In my presentation I will outline our research aims and progress in the Post-Li Cluster of Excellence (POLiS), between the Karlsruhe Institute of Technology, Ulm University and the Justus-Liebig University in Gießen, which solely focuses on the development of post-Li battery systems. In addition, I will highlight examples from my research activities on potassium and calcium batteries, in the context of the Einsteinium short-term visiting program.
