Massachusetts-based battery recycling startup Ascend Elements has also developed a chemical process for graphite purification. Dubbed “hydro-to-anode,” Ascend Elements’ process “comes from some of the work we’ve done on hydro-to-cathode,” the company’s patented hydrometallurgical process for recycling cathode materials, said Roger Lin, the vice president of global marketing and government relations at the firm. Lin said that Ascend Elements is able to take graphite that’s been contaminated during an initial shredding step back to 99.9 percent purity, exceeding EV industry requirements, while also retaining the material properties needed for high performance anodes. In October, Ascend Elements and Koura Global announced plans to build the first “advanced graphite recycling facility” in the U.S.
