Carbion makes battery-grade graphite from biomass, using abundant waste feedstocks to support domestic manufacturing of a material central to energy infrastructure. The company focuses on strengthening supply-chain independence while offering a more affordable and stable graphite source for customers.
GreenCarbonGreenCarbon turns domestic agricultural waste into hard-carbon anodes and other advanced carbon materials for lithium-ion and sodium-ion batteries. Its plant-powered approach is designed to reduce reliance on foreign supply chains while permanently storing carbon in energy-storage applications. The company also develops carbon materials for uses beyond batteries, including graphene nanomaterials and construction applications.ANNAPOLIS JUNCTION, MD
TerrionFrom its Frederick, Maryland plant, Terrion converts American coal into synthetic graphite, building a domestic supply chain for a material the United States currently imports. Its Carbonyx process uses coal culm without new mining and produces spec-grade graphite for demanding energy, defense, nuclear, and industrial applications. Terrion’s first facility is a 26,000-square-foot operation with stated capacity of 1,500 tons per year, with larger-scale production planned.WALKERSVILLE, MD
M2Graphite TechnologiesU.S.-owned and based, M2Graphite Technologies began commercial production in 2021 as a domestic manufacturer of synthetic graphite for lithium-ion battery makers. Its Sanborn, New York, center combines production with research and development, and the company says its material is qualified for commercial electric-vehicle and Department of Defense aerospace applications. M2Graphite is also active in efforts to strengthen a North American battery-materials supply chain.SANBORN, NY
