"uses electricity to split neodymium chloride molecules, drawing pure neodymium to cathode... eliminates 2 major, energy-intensive steps... reduces production costs from >14 to approximately $5/ kg... no harmful gas byproducts... anode design prevents degradation, allowing continuous use... complete mine-to-magnet U.S.-based manufacturing chain... future: making scalable, testing new deposition approaches to stabilize anode... method can be extended to other critical rare-earth metals"
