Grant Proceeds Will Accelerate Research Into Anti-Corrosive Additives in Molten-Salts-Based Heat Transfer Fluids For Nuclear Reactors.

DALLAS, Dec. 29, 2025 -- Solidion Technology Inc. ("Solidion" or the "Company") (Nasdaq: STI), an advanced battery technology solutions provider, was notified by the U.S. Department of Energy (DOE) that it has been awarded a grant to scale up the synthesis of a carbon-nanosphere material that will be used as an anti-corrosive additive in molten-salts-based heat transfer fluids for advanced molten salt nuclear reactors.

The Company previously announced that it had received the prestigious 2025 R&D 100 Award in partnership with Oak Ridge National Laboratory (ORNL), for innovation in Electrochemical Graphitization in Molten Salts (E-GRIMS) as well as a grant to advance research and development of Electrochemical Manufacturing of High-Performance Graphite Based on Biomass-Derived Carbon funded by ARPA-E, the Advanced Research Projects Agency, from their highly competitive OPEN program.

KEY HIGHLIGHTS OF SECOND DEPARTMENT OF ENERGY GRANT

• Collaboration: Research to be conducted jointly with Oak Ridge National Laboratory
• Diversification: Technology will develop a nanofluids-based energy material, engineered colloidal suspension of hollow carbon nanoparticles in conventional molten salts, to enhance heat transfer and reduce corrosion in nuclear reactors, which is critical for reducing costs, increasing safety, and accelerating the commercialization of small modular nuclear reactors such as advanced molten salt reactors.

Jaymes Winters, Chief Executive Officer of Solidion Technology, stated:

"Consecutive awards from the Department of Energy is proof positive that Solidion is not only innovative in energy storage, but energy processes, liquids and materials as well."
