Solidion Technology Awarded Its Third Grant From The U.S. Army STTR Program

Grant Proceeds Will Accelerate Research Into Advanced Fiber-based Electronic Battery Systems

DALLAS, Jan. 20, 2026 /PRNewswire/ — Solidion Technology Inc. (“Solidion” or the “Company”) (Nasdaq: STI), an advanced battery technology solutions provider, was notified by the U.S. Department of War/Army STTR Program that it has been awarded a grant to develop an advanced fiber-based electronic battery system built on a coaxial carbon nanotube (CNT) yarn architecture. This marks the third grant Solidion has received in the last six months.

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 and 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.

KEY HIGHLIGHTS OF SOLIDION’S THIRD GOVERNMENT GRANT

• Collaboration: Research to be conducted jointly with The University of Texas at Dallas
• Diversification: This innovation is a flexible, rechargeable lithium-ion battery in fiber form: a CNT yarn serves as both the structural core and current collector of the anode, integrated with Solidion’s silicon (Si) as the high-capacity anode material.

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

“Advancements in advanced fiber based electronic battery systems are a part of the larger commitment by the Department of War to innovate and collaborate with cutting edge U.S. companies such as Solidion.”
