Scope

Molten salt batteries are promising candidates for cheap grid scale energy storage, a key ingredient of future energy systems based mainly on volatile renewable sources as wind and solar power. Such cells offer several unique advantages such as cheap and abundant raw materials, high safety, and potentially very long cycle life. To realize these promises, challenging problems in high-temperature electrochemistry, materials science, thermal management and metallurgy have to be addressed. Fluid mechanics enters the field since we are dealing with cells having at least a partially liquid interior. This workshop aims to support the trend, to offer a platform for discussion, and to facilitate future collaborations. While the focus shall be on high-temperature batteries, talks on related devices or processes (e.g., aluminum reduction cells) are equally welcome and clearly do belong to the scope of the workshop.

Topics

• liquid metal batteries, Na-S, Na-NiCl_2, Na-ZnCl₂ and any other high temperature batteries
• experiments, simulation and theoretical modelling
• electrochemistry
• corrosion and material selection
• fluid dynamics
• cell design and engineering
• scale-up, dimensioning and grid integration
• stack design, heat management and insulation
• battery management systems
• social science
• life cycle assessment

Confirmed invited speaker

• Hojong Kim: "Applications of Molten Salts Electrochemistry" (Penn State College of Earth and Mineral Sciences)
• Matthias Schulz: "Cell and System Development of Next Generation ZEBRA Batteries" (Fraunhofer Institute for Ceramic Technologies and Systems IKTS)

Abstracts

Please use the LaTeX-template provided here to prepare your abstract. Should you prefer a different word processor, please follow closely the layout of the file ‘abstract_template.pdf’ (included in the package). Submit the abstract as a pdf-file to msb2025@hzdr.de.

Final programme

The final programme will be available soon after the deadline of abstract submission.

Workshop Venue

The workshop will be held in the Hotel Occidental Dresden Newa which is very close to the Dresden central station and in walking distance to the city’s major sites Frauenkirche (Church of Our Lady), Brühl's Terrace and the river Elbe. Dresden, the capital of Saxony, is well known for its cultural and historical highlights. Besides the workshop program, a visit to the Liquid Metal Laboratory of the Helmholtz-Zentrum Dresden-Rossendorf, a city tour as well as a visit of Saxon Switzerland is planned to be offered.
