ELLIPSE Conference 2025
The ELLIPSE 2025 Conference (Electrolytes and Interfaces in Post-Li Batteries) brought together over 120 leading scientists and industry experts for two days of intense discussion and collaboration on the future of electrochemical energy storage. As a satellite meeting of the International Society of Electrochemistry, the event showcased pioneering research on next-generation battery chemistries, electrolytes, interfaces, and advanced characterization techniques.
Hosted in Ulm, the two-day program featured talks from world-renowned researchers including Jürgen Janek (Justus-Liebig-Universität Giessen), Yang Shao-Horn (Massachusetts Institute of Technology), Alexandre Ponrouch (Institut de Ciència de Materials de Barcelona, ICMAB-CSIC), and Øystein Gullbrekken (NTNU), among others. Their presentations covered topics ranging from modeling of solid-electrolyte interfaces to operando analysis of complex electrochemical processes.
The first day concluded with a vibrant poster session highlighting 45 contributions from emerging researchers. The Poster Awards, sponsored by rhd instruments GmbH & Co. KG, recognized outstanding scientific achievements and innovative methodologies:
-
🥇 Tommaso Mavolo (Justus-Liebig-Universität Giessen) – In-Situ Characterization of SEI Formation at the Sodium Metal / PEO:NaTFSI Interface Using ToF- and Orbitrap-SIMS Analysis
-
🥈 Laurin Derr (Karlsruher Institut für Technologie) – Time-Resolved Analysis of Entropy Production During Sodiation of Hard Carbon
-
🥉 Bingbing Li (Tohoku University) – Revealing the Interfacial Reaction Mechanisms in Lithium–Oxygen Batteries by In Situ EC-AFM at Single-Layer Graphene
Reflecting the growing momentum in post-lithium research, ELLIPSE 2025 demonstrated the collaborative spirit driving the next generation of sustainable and high-performance energy storage solutions. As participants departed, one message resonated clearly: the future of batteries depends not only on new materials, but on a deeper understanding of the interfaces that power them.
