From October 7 to 9, 2026, the Seventh International Bunsen Discussion on Solid-State Batteries (SSB VIIl) took place at the House of Logistics and Mobility (HOLM) in Frankfurt am Main. The conference brings together scientists and industry representatives to present the latest developments in the field of semi-solid-state and all-solid-state batteries and to discuss new approaches to battery technology. With a total of 37 presentations and 158 poster presentations, the event provided a platform for an intensive scientific exchange.

Hamid Reza Sharafi from Keylab Glass Technology also attended the conference and presented recent results from his research on glass-based gel-polymer electrolytes. In a presentation titled “Fabrication of Gel Polymer Electrolyte Films for Semi-Solid-State Batteries” he introduced a new fabrication method for polymer membranes with integrated glass particles. The developed structure enables the formation of a gel-polymer electrolyte system after the electrolyte is added. The combination of a polymer matrix and glass is intended to specifically influence both the mechanical and electrochemical properties of the electrolyte system. The poster was selected for a “Poster Speed Talk” during which the research findings were presented in a brief talk and then discussed with audience of experts.

The numerous discussions with scientists and industry representatives provided valuable insights for further research and potential future collaborations. The findings and professional exchange will be incorporated into upcoming work on the development of new materials and concepts for semi-solid-state batteries.
