Scaffold Prime®

Precision carbon scaffolding for silicon anodes
Scaffold Prime® is Group14’s patented, reliable, and commercial-scale manufacturing platform designed to produce SCC55®. Manufactured through our elegantly simple two step process, we start by synthesizing carbon to create the perfect carbon scaffold. We then create silicon and tuned internal void space inside it, which results in the final product: SCC55®.
