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.
Electroflow Technologies
Electroflow Technologies is a San Bruno, California startup building an electrochemical direct lithium extraction (DLE) process that turns low-grade, dilute North American brines into battery-grade lithium and lithium iron phosphate (LFP) powder. By collapsing a conventional 10-step brine-to-LFP process down to three steps and using lithium-selective electrodes, the company aims to produce LFP cathode material domestically at under $2,500 per metric ton - roughly 40% below current Chinese producers - while using minimal water, chemicals, and electricity.
