Group14’s core technology is SCC55™, a silicon-carbon composite anode material offering superior energy density and faster charging than graphite. Its manufacturing process creates a stable silicon-carbon structure that prevents degradation over charge cycles, is compatible with existing lithium-ion battery production, and emphasizes sustainability through abundant materials and efficient, scalable methods.
SCC55™ is Group14’s flagship silicon-carbon composite anode material. It replaces conventional graphite in lithium-ion batteries to deliver 50% longer runtime, faster charging, enhanced electron conductivity, higher lithium-ion storage, and consistent performance over numerous cycles. The material integrates into existing battery formats for EVs, consumer electronics, and large-scale storage.
In 2024, Group14 opened a joint venture factory in Sangju, South Korea (2,000 tonnes annual capacity). It began constructing a Moses Lake, Washington facility (4,000 tonnes capacity, completion in 2025). The U.S. Department of Energy selected Group14 for up to $200 million award negotiation to build a silane factory.
Series C round in 2022 raised $614M, led by Porsche AG, with participation from Microsoft Climate Innovation Fund, SK Inc, OMERS Capital Markets, Decarbonization Partners, Riverstone Holdings LLC, and Vsquared Ventures. The round was also supported by grants from the U.S. Department of Energy.
