Group14 Technologies has announced that its newest silicon battery materials factory in Sangju, South Korea, has begun EV-scale production of its proprietary silicon battery material, SCC55®. The state-of-the-art facility is designed to produce up to 2,000 metric tons annually, enabling 10 GWh of extreme-fast-charging battery capacity as production ramps.

Why it matters

This EV-scale silicon battery materials factory strengthens critical minerals security by reducing dependence on Chinese graphite, a strategic material used in batteries and other critical applications. SCC55 significantly reduces the volume of graphite required in battery production, helping to diversify supply, lower dependence on concentrated sources, and improve the resilience of domestic and allied battery manufacturing.

The details

The Sangju factory operates alongside Group14's existing commercial factory in Woodinville, Washington, with a second U.S. facility in Moses Lake, WA, nearing completion. Group14's silicon battery materials factories were designed to rapidly scale and easily "drop in" to commercial battery cell production lines. SCC55 is compatible with multiple cell formats and chemistries, including LFP, LMFP, and high-nickel systems, and is already powering millions of products worldwide across EVs and electrified mobility, consumer electronics, drones, AI-enabled data centers, and other applications.
