GDI

GDI is a battery technology company that develops and manufactures 100% silicon anodes for lithium-ion batteries, offering improved performance over standard graphite-based batteries. The company patented silicon anode technology uses a continuous, flexible silicon layer that addresses the swelling problem common in other silicon anode designs during charge and discharge cycles. GDI anodes provide 30% greater energy density, 3x faster charging, better extreme cold performance, and supply chain security compared to graphite anodes. The company advanced manufacturing process, powered by AGC PlasmaMAX technology, offers 5-10x faster silicon deposition, making silicon anodes commercially viable at scale. GDI anodes are designed to integrate seamlessly into existing battery manufacturing processes and adapt to any lithium battery architecture, serving industries including defense, drones, medical technology, e-mobility, and aerospace. Founded in 2009 and headquartered in Rochester, New York, GDI has raised approximately $46.7 million in Series A funding from investors including the European Investment Bank, EIT InnoEnergy, Helios Climate Ventures, and the U.S. Army.
