About Group14
Group14 Technologies is a US-based manufacturer and supplier of rechargeable lithium-silicon battery technology headquartered in Woodinville, Washington. Its flagship product is SCC55®, a silicon-carbon composite anode material that can be used as a drop-in replacement for conventional graphite in existing lithium-ion production lines. SCC55® enables 0–100 % charging in 90 seconds, 43 % higher energy density, and up to 3,000 charge cycles. The company operates a global network of production facilities: a commercial factory in Woodinville, a 20-GWh factory in Moses Lake (Washington), a 10-GWh factory in Sangju (South Korea), and a silane factory in Spreetal (Germany) with up to 1,000 tonnes of capacity. Buyers include Porsche and Amperex Technology Limited (ATL); applications include electric vehicles, consumer electronics, grid-adjacent energy storage for AI data centers, defense, aerospace, and electric aviation. Group14 relies on more than 200 granted patents and has raised a total of USD 1 billion in equity.
