Anovion Sanborn Synthetic Graphite Plant

Anovion's synthetic graphite anode material plant at Sanborn in Niagara County, New York — the operating site behind the company's claim to be North America's first commercially operational supplier of synthetic graphite anode material, shipping in the United States since 2021, and the location of its Technology Center of Excellence. Anovion's DOE Office of Manufacturing and Energy Supply Chains grant (award DEMS0000006, US$117,000,000 obligated) was terminated in DOE's October 2025 award cancellations with only US$13,782,513.18 outlayed, according to USAspending.gov and reporting on DOE's confirmation; the facility is retained here with that termination recorded rather than deleted. The operating status carried below rests on a September 2022 company release; no later source confirming Sanborn's current operating state was located on this pass, and no sourced capacity figure for Sanborn was found.
