GDI is a global innovator in battery technology, specializing in the development and production of 100% silicon anodes for lithium-ion batteries. Founded by Rob Anstey, the company creates advanced battery components that significantly improve charging speed and energy density compared to traditional lithium-ion batteries. GDI’s patented silicon anodes integrate seamlessly with existing battery manufacturing processes, making them ideal for mass production. The company serves various sectors, including electric vehicles, aviation, aerospace, mobility, and landscaping equipment, helping accelerate the transition to sustainable transportation solutions.
Battery Technology
GDI’s primary innovation lies in its 100% silicon anode technology, which offers substantial improvements over conventional graphite-based anodes. The technology enables batteries to achieve 30% greater energy density, reaching up to 3200 mAh/g. This enhanced capacity translates to extended range for electric vehicles, potentially exceeding 500 miles on a single charge.
The silicon anodes also enable rapid charging capabilities, allowing batteries to charge from 10% to 75% in just 15 minutes. This performance can be maintained through hundreds of charging cycles without significant degradation. Safety features are integrated into the design, with the anodes demonstrating excellent thermal stability and passing rigorous safety tests, including nail penetration evaluations.
Manufacturing occurs through an efficient roll-to-roll production process that maintains consistent quality from the first to the millionth unit. This scalable approach allows GDI to meet increasing demand while maintaining high quality standards. The company aims to achieve gigawatt-scale production by 2028, positioning its technology for widespread adoption in high-performance applications.
Recent Projects
In 2024, GDI secured a €20 million quasi-equity loan from the European Investment Bank to advance its silicon anode technology development. The company plans to begin commercialization by 2026. Additionally, GDI was recognized as a winner in the U.S. Army’s 2023 xTechPrime competition, receiving both a cash prize and an invitation to submit for a Direct to Phase II Army SBIR contract.
Investors
GDI’s development is supported by significant financial backing, including a $13.3 million Series A funding round led by EIT InnoEnergy and Helios Climate Ventures. The company has also received funding from government sources, including the U.S. Army Research Labs and the U.S. Department of Energy, demonstrating strong institutional confidence in their technology.
