Solidion Secures Third U.S. Army STTR Grant in Six Months for Fiber-Based Battery Tech
Event summary
- Solidion Technology awarded third U.S. Army STTR grant in six months for coaxial carbon nanotube (CNT) yarn battery architecture.
- Grant funds research collaboration with The University of Texas at Dallas on flexible, rechargeable lithium-ion fiber batteries.
- Company previously received 2025 R&D 100 Award and ARPA-E grant for molten salt nuclear reactor materials.
- Solidion holds 525+ patents covering silicon anodes, biomass-based graphite, and advanced battery technologies.
The big picture
This marks continued U.S. government validation of Solidion's battery innovation pipeline, following recent ARPA-E and R&D 100 recognition. The fiber-based architecture represents a potential breakthrough for flexible energy storage in defense and aerospace applications. With three grants in six months, Solidion is emerging as a key player in next-generation battery materials research.
