Charged EVs | Monomyth Materials acquires NanoGraf to pair SiOx silicon anodes with its domestic synthetic graphite platform

Monomyth Materials has acquired the assets of NanoGraf, a Chicago-based silicon anode company spun out of Northwestern University and Argonne National Laboratory, pairing SiOx technology and a defense-validated IP portfolio with its domestic synthetic graphite business. Financial terms weren’t disclosed.

The NanoGraf assets become the foundation of a new subsidiary, M2Innovations, focused on advanced battery materials and prototype cell development from R&D through pilot scale. It sits alongside M2Graphite—Monomyth’s synthetic graphite business, simultaneously rebranded from Anovion Technologies—which handles commercial-scale production. The combination covers essentially the full active anode stack: graphite and silicon together make up virtually all of the active material in a lithium-ion anode, and both are currently dominated by Chinese supply.

Over 90% of active anode material is sourced from China today, and China accounts for more than 60% of global SiOx capacity. NanoGraf’s SiOx technology is already deployed in consumer electronics and military applications, with validation from federal defense and energy agencies, including the Department of Energy.

M2Graphite was assembled from graphite assets formerly held by Amsted Industries and Pyrotek. Amsted remains a minority shareholder. The Bainbridge, Georgia site is slated to be the first of several facilities, backed by three planned capital programs of more than $1 billion each. Monomyth has invested more than $100 million in the platform since 2022.

Francis Wang, who led NanoGraf through its growth stage, will join the M2Innovations advisory board.
