Group14 Technologies makes SCC55, a silicon–carbon composite anode material that replaces graphite in lithium-ion batteries. It increases energy density by up to about 50%, supports faster charging, and often lasts 1,500+ cycles, working across chemistries like LFP, LMFP, and high-nickel formats. The company sells this material B2B to battery makers and OEMs worldwide, backed by a global BAM manufacturing footprint. Its goal is to scale silicon-based anodes to meet rising demand and strengthen regional supply chains for batteries.

Group14 has started production at its BAM-3 factory in South Korea, capable of producing 2,000 metric tonnes of silicon battery materials annually—enough for 10 gigawatt-hours of energy storage or approximately 100,000 long-range EVs. The facility was originally a joint venture with SK, which owned 75% before selling its stake to Group14 last summer. Group14's silicon anode technology uses a hard carbon scaffold to prevent swelling and crumbling whilst enabling fast charging. The company works with Porsche's Cellforce Group, StoreDot, Molicel and Sionic. Some customers are using the materials to boost energy density by up to 50%, whilst others focus on fast-charging capabilities, including designs that can charge batteries from flat to full in 90 seconds.
SK leads Series D to accelerate the scale and global delivery of SCC55®. Group14 also acquires the 75% balance of the South Korea joint venture with SK, taking direct control over the manufacture of the company's silicon battery material in Asia. WOODINVILLE, Wash., Aug. 20, 2025 /PRNewswire/ — Group14 Technologies today announced that it has closed a US$463M round led by SK, Inc., with strong participation of other existing investors, including Porsche Investments, ATL, OMERS, Decarbonization Partners, Lightrock Climate Impact Fund, Microsoft Climate Innovation Fund, and others. The funds will be used to continue scaling the manufacture of Group14's silicon battery material, SCC55, in the U.S. and South Korea, and help meet overwhelming demand amid surging requirements for energy storage worldwide. In addition, Group14 obtained full ownership of its joint venture with SK Inc., located in Sangju, South Korea. Formed in 2021, the joint venture's battery active materials (BAM) factory produces Group14's flagship technology, SCC55, at EV scale to support the global battery manufacturing industry. “This is a defining moment for Group14 and a clear signal that the future of high-performance energy storage, powered by our silicon battery material, is already here,” said Rick Luebbe, CEO and Co-Founder of Group14. “We're strengthening regional battery supply chains and safeguarding our customers from global trade uncertainty.” As Group14's third commercial battery active materials factory, BAM-3 is strategically located in Asia, home to the world's largest battery manufacturers. In September 2024, the 10-gigawatt-hour factory began delivery of SCC55 to over 100 electric vehicle and consumer electronics battery manufacturing customers worldwide. “Group14 technology is already integrated into millions of ATL batteries powering AI-enabled smartphones,” said Joe Kit Chu Lam, Executive Vice President at ATL, a subsidiary of TDK Corporation. “We support even broader delivery of their silicon anode material to power the next generation of high-performance silicon batteries.” Group14's first and second BAM factories are located in Washington state. The company is expanding silicon battery infrastructure in Europe with a state-of-the-art silane gas factory in Germany, which will supply a critical precursor for next-generation energy storage technologies. Following the Series D round, Group14 has raised over US$1B of equity to fund its growth. About Group14 Technologies Group14 Technologies is a global leader in advanced silicon battery materials, transforming the future of rechargeable energy storage.
