6K
6K is a North Andover, Massachusetts advanced materials company that uses its proprietary UniMelt microwave plasma technology - which reaches roughly 6,000 degrees, hence the name - to produce battery cathode materials and additive-manufacturing metal powders faster, cleaner, and with fewer processing steps than conventional methods. Spun out of research at MIT and the University of Connecticut, the company operates through two divisions, 6K Energy (battery cathode active materials) and 6K Additive (sustainably sourced metal powders), and is building a domestic U.S. supply chain for critical materials backed by federal grants and more than $348 million in venture funding.
