Group14 Ramps First EV-Scale Silicon Anode Plant in South Korea, Strengthening Non-Graphite Supply Chain

New updates have been reported about Group14 Technologies.

Group14 Technologies has begun EV-scale production of its SCC55 silicon battery material at a new factory in Sangju, South Korea, positioning the company as a key non-graphite anode supplier to global cell makers. The plant is engineered for up to 2,000 metric tons of annual output, equivalent to roughly 10 GWh of battery capacity, and complements Group14’s commercial facility in Woodinville, Washington, with a second U.S. site in Moses Lake nearing completion.

CEO Rick Luebbe said the milestone makes Group14 the only player manufacturing silicon battery materials at true global scale, enabling OEMs and cell producers to shift away from graphite while gaining supply-chain security. The company’s SCC55 material, protected by more than 170 patents, is compatible with multiple chemistries including LFP, LMFP, and high-nickel systems, is already deployed in millions of devices, and has reported performance of 0–100% recharge in 90 seconds and energy density gains above 40% in commercial programs.

CTO Rick Costantino noted that customers, including established cell manufacturers and battery technology partners, have demonstrated over 1,000 cycles with industry-leading energy density and ultra-fast charging, with some designs achieving 1,500 to 3,000 cycles at 80% capacity retention. These metrics indicate that SCC55 has overcome historic durability concerns around silicon anodes, clearing a key barrier to mainstream automotive and grid-scale adoption.

Strategically located near major Asian battery makers, the Sangju facility is designed as a drop-in supply source for existing cell lines and is already serving more than 160 customers worldwide. By delivering roughly five times the energy capacity of graphite per ton, SCC55 can replace multiple tons of graphite, directly addressing U.S. Geological Survey concerns over graphite concentration risk, particularly given China’s dominance in graphite-based anodes.

Group14’s intellectual property footprint spans the core EV and battery manufacturing regions, and the company actively enforces its patents to limit IP risk for customers as silicon-based cells scale. To fund this buildout of a global silicon battery materials platform, Group14 has raised over $1 billion in equity, positioning it to capture growing demand from EVs, energy storage, and high-performance electronics as the market transitions to next-generation anode technologies.
