ECerS 2025 Satelite Symposium and Exhibition  /  September 03, 2025  -  September 04, 2025

SBS6 – International Sodium Battery Symposium

Sodium batteries represent the most promising and short-term available post-lithium battery technology family. This family has members spanning generations, some of whom have over 40 years of history and have been commercialized and others who are being developed in the field of basic research. The variety of technological options is enormous and opens up a range of promising new possibilities for sustainable electricity storage.

The Sodium battery Symposium – SBS is the conference for scientific exchange on sodium batteries in Europe and looks back on a six-year tradition with alternating organization by Fraunhofer IKTS and the research group of Prof. Philipp Adelhelm (Helmholtz-Zentrum Berlin – HZB).

SBS6 is organized as a satellite symposium of ECerS XIX by Fraunhofer IKTS.

The SBS6 will cover all aspects of Na-based batteries, from fundamental research up to systems, along with testing, markets and applications. The SBS6 wants to strengthen the community around sodium batteries and intends to enable an open exchange of information on current scientific results, research interests, as well as market requirements. Scientists, engineers and managers are invited to report on their results, developments and future prospects orally or via posters, or display their products and services as an exhibitor. This 6th SBS welcomes contributions on recent trends and discoveries on:

  • Sodium batteries and systems – experiences from R&D to real-world applications
  • Innovative sodium battery cell concepts including
    • Liquid and polymer electrolyte cell concepts
    • Solid state and all solid state concepts
    • High temperature sodium cells (Na-MeCl2, NaS)
    • Flow, all liquid and alternative cell concepts
  • Electrolytes and electrodes – material, design and production
  • Anode and cathode materials – from material science to production processes

Scientists, engineers and managers are invited to report on their results, developments and future prospects orally or via posters, or display their products and services as an exhibitor.

Together with the members of the scientific and organizing committees, we look forward to meeting you in Dresden.

Yours, 
Michael Stelter
