NOVONIX has delivered a mass production qualification sample—a “C-sample” in automotive supply chain terms—of its synthetic graphite anode active material (AAM) to Panasonic Energy, marking a significant step toward establishing a US-sourced battery anode supply for Panasonic’s cell manufacturing.
NOVONIX says this is the first known synthetic graphite AAM C-sample produced in North America. Synthetic graphite is the dominant anode material in lithium-ion batteries, and production is heavily concentrated in China. A domestically produced C-sample represents real progress toward US supply chain independence.
A C-sample is a mass production-intent sample—distinct from earlier development (A-sample) and prototype (B-sample) stages—but it’s not the finish line. NOVONIX says its own testing shows the material meets Panasonic’s specifications, but formal validation is still subject to Panasonic’s assessment over the coming months. NOVONIX reaffirmed its earlier guidance that mass production for Panasonic is expected to begin in the second half of 2027, contingent on successful completion of that qualification process.
“The delivery of a mass production C-sample to Panasonic is an important moment for NOVONIX and for the development of a secure North American battery materials supply chain,” said CEO Mike O’Kronley. “We are now one step closer to realizing a fully domestic supply chain in the US.”
