- Prior Finance: $13.3M Series A in Sept 2022; additional US government grants from US Army, DOE, DLA totalling $3M.
- Debt/Equity: €20M issued by European Investment Bank via InvestEU to support EV-scale operations in Germany.
Products & Services
- Silicon Anode Material & Processing: Raw silicon powder + roll-to-roll coating service on copper alloy substrate from Schlenk AG, using AGC plasma/coating tech .
- Cell Partnerships: Joint-development with Navitas (third-party validation) and undisclosed EV cell manufacturer; target med-tech and defense first, expanding to EV by 2030.
Market Context
- Market Size: Silicon anode materials projected to exceed $15B by 2035, driven by EV demand .
- Strategic Need: China controls >90% of global graphite refining—GDI’s silicon replaces graphite and reduces geopolitical risk.
- Scale Roadmap: 100 MWh scale by 2024; 10 GWh by 2028 .
Market Impact: Strengthening US Battery Independence
The US currently imports over 90% of its graphite anode materials from China, making domestic alternatives a top national priority. GDI’s silicon-based solution aligns with the Biden administration’s push for clean energy independence, and supports the Inflation Reduction Act’s incentives for US-made EV battery components.
The global EV battery market is projected to hit $225 billion by 2030, with anode innovations playing a key role in driving faster adoption. As automakers race to offer faster charging without sacrificing range, GDI’s technology stands at the forefront of solving a critical bottleneck.
Leadership and Vision
GDI is led by a team of battery veterans, nanotech researchers, and materials engineers, including:
- Dr. Robert Simmons, CEO – former Tesla and Samsung SDI battery materials lead
- Dr. Elena Cheng, CTO – nanomaterials expert with over 30 patents in energy storage
- Alex Morgan, COO – former VP at QuantumScape and Panasonic Energy North America
The company aims to license its technology to major cell manufacturers while also exploring joint ventures with automakers for direct integration.
