Previously Announced Recent Business Highlights

Business Development

Successful demonstration of a high-power 9.5Ah pouch cell designed for industrial and military drone applications. The prototype delivered exceptional power stability, retaining approximately 95% of its capacity at a 10C discharge rate, a significant improvement over typical market pouch cells, which average 78% retention at 5C. Solidion expects to make the pouch cell commercially available in Q2 2026.
The Company unveiled its new PEAK Series, an advanced UPS battery system engineered specifically for AI data centers, leveraging the Company's high-performance 5500 silicon-carbon anode cell. The system delivers up to 30% space savings, significantly lower total cost of ownership, and up to three times longer life than conventional backup solutions. Commercial availability is expected in 2026, with Solidion currently working with select data center partners on early integration and testing.

Technological Advancements, Business Development and Corporate Updates:

The Company previously announced that it has entered into a non-binding Memorandum of Understanding with an entity that manufactures and distributes energy storage systems.
The Company has been awarded a grant to advance research and development of Electrochemical Manufacturing of High-Performance Graphite Based on Biomass-Derived Carbon. This award is one of the projects funded by ARPA-E, the Advanced Research Projects Agency, from their highly competitive OPEN program.
The Company 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 from the U.S. Department of Energy (DOE).
The Company has been awarded a grant to develop an advanced fiber-based electronic battery system built on a coaxial carbon nanotube (CNT) yarn architecture from the U.S. Department of War/Army STTR Program.
Solidion Technology completed a major restructuring of its August 2024 equity financing, eliminating all Series C and D Pre-Funded Warrants, along with the corresponding derivative liability, significantly strengthening the balance sheet and reducing future dilution risk. Long-term investors Madison Bond LLC and Bayside Project LLC converted their entire warrant allocation into common stock, committing to hold the shares for at least 12 months, which enhances shareholder alignment and supports Solidion's long-term growth strategy.
Solidion Technology and Oak Ridge National Laboratory received a 2025 R&D 100 Award for their jointly developed E-GRIMS technology, which enables a more energy-efficient, scalable, and environmentally sustainable method of producing graphite anode materials. This breakthrough significantly reduces the carbon footprint of lithium-ion battery manufacturing and supports next-generation energy storage, marking a major advancement in sustainable battery materials innovation.
Secured newly granted U.S. patents for proprietary technology that enables the conversion of existing lithium-ion manufacturing facilities to produce solid-state batteries through in situ solidification. This innovation significantly reduces fire risk by transforming flammable liquid electrolytes into solid-state form.
Breakthrough in Lithium-Sulfur Battery Technology: Solidion announced its Li-S batteries have achieved a cell energy density of 380 Wh/kg, with a near-term target of 450 Wh/kg. Validated by a leading EV battery manufacturer, this milestone advances our vision of low-cost, cobalt- and nickel-free batteries, potentially doubling the energy density of today's lithium-ion cells.
Filed Patent Applications for Silicon Anode Technology: Solidion filed several U.S. patent applications for a novel, cost-effective method of producing graphene-hosted silicon anodes—an innovation aimed at significantly improving EV battery energy density and reducing production risks and costs.

CEO Statement:

"We are immensely proud to announce our first-ever quarterly revenue. This milestone is a direct result of our team's relentless execution and the strong market response to our superior energy storage technology. It proves that our vision for our commercialization is resonating with customers, establishing an extraordinary foundation for our long-term growth."
