Problem
Traditional lithium-ion batteries rely on graphite anodes, which limit energy density and slow charging times. This constrains the range of electric vehicles, the battery life of consumer electronics, and the rapid-response power needed for data centers and other high-demand applications.
Solution
Group14 Technologies provides SCC55®, an advanced silicon anode material engineered as a direct drop-in replacement for graphite. By combining carbon's structural stability with silicon's extreme energy capacity, SCC55® solves silicon's historic expansion challenges while enabling cell manufacturers to upgrade existing Li-ion production lines instantly—no retooling required. The company is manufacturing metric tons of silicon battery materials right now, operating a global network of advanced manufacturing facilities in the U.S. and South Korea, with additional silane production in Germany. This approach accelerates electrification across electric mobility, grid-scale energy storage, consumer electronics, defense, and aerospace.
Target Audience
Primary customers are lithium-ion cell manufacturers and battery producers serving electric mobility, consumer electronics, data center energy storage, and defense/aerospace applications.
