Graphite One has secured a site in Conneaut, Ohio for its planned Active Anode Materials facility. The site offers direct access to Lake Erie and the Great Lakes shipping corridor, multi-line CN rail connectivity and an existing on-site substation.
The company aims to complete construction in Q4 2027. Phase One production is planned at 10,000 tonnes per year—split across 4,000 tonnes of energy storage material, 3,000 tonnes of fast-charging material and 3,000 tonnes of high-energy-density material, all for lithium-ion battery applications in EVs and grid storage. A Phase Two expansion targeting 25,000 tonnes per year of graphitization capacity is planned for Q3 2028.
Graphite One says it has delivered commercial-grade anode material samples—in quantities of up to 20 kg—to three major EV manufacturers and three battery companies, all of which are currently running specification testing. The company has entered binding offtake discussions with participants from that group, though no agreements have been signed.
The US is currently 100% import-dependent for natural graphite. Graphite One’s vertically integrated model links the Graphite Creek deposit in Alaska—identified by the USGS as the largest graphite deposit in the country—to Ohio processing facilities via the Port of Nome.
