SOLSTICE has produced a new image movie which explains the SOLSTICE battery concept and its application in industry.

From 20th to 22nd May 2025, SOLSTICE organized the „International Workshop on Molten Salt and Liquid Metal Batteries“ (MSB 2025) in Dresden, Germany. This was the last meeting for the SOLSTICE project members and an excellent opportunity to exchange with experts from the molten salt battery community.

SINTEF was the host of this year’s SOLSTICE Consortium Meeting in Trondheim. Thanks for the perfect organization and your hospitality!

EMPA Quarterly features an article on the storage solutions developed in SOLSTICE with a focus on the contribution of EMPA and Horien, Image: EMPA. https://www.empa.ch/web/s604/salzbatterie & https://www.empa.ch/documents/d/s604/eq84_en_final_web

SOLSTICE will be present at the LOLABAT Final Event. Online participation is free and open to all interested parties: https://events.teams.microsoft.com/event/1893ed4d-2086-4f1f-95af-59199d3881ac@76e3e3ff-fce0-45ec-a946-bc44d69a9b7e

Sajad Rahimi’s (EMPA) presentation on a „New Electrode Formulation for High-Temperature Na-ZnCl2 Batteries“ at the Swiss Battery Days (https://swissbatterydays.empa.ch) was received with great interest.

During his guest stay at Helmholtz-Zentrum Dresden-Rossendorf, Dr. Wenjin Ding from DLR gave an overview talk on SOLSTICE and corrosion in molten salts at the Chair of Hydrogen and Nuclear Energy at TU Dresden, which was very well received.

Colleagues from SOLSTICE and the Paul Scherrer Institute (PSI) reported on cell designs suitable for the neutron-radiography of high-temperature Na-ZnCl2 batteries in a recently published paper. https://iopscience.iop.org/article/10.1149/1945-7111/ad3b78

The SOLSTICE partners Politecnico di Torino and FZSoNick published a joint paper on promising glass-based sealants for Na-Zn batteries in Ceramics International. https://doi.org/10.1016/j.ceramint.2024.01.367

Catherine K. W. Solem from SINTEF visited HZDR to take part in open cell experiments designed to shed light on the processes in the anode compartment.
