Founded in 2012, NanoGraf manufactures silicon-based anode materials that enable higher battery capacity. It is the largest producer of silicon oxide anode material in the US and the maker of the M38, a high-energy-density 18650 lithium-ion cell. Its technology has the potential to replace graphite-based anodes and significantly improve lithium-ion battery performance, offering extended EV range, improved low-temperature performance, and faster charging.
