Room-Temperature Electrochemical Metallization of Rare Earth Elements A low-energy, low-hazard alternative to molten-salt electrolysis for sustainable REE production. Technology Summary This invention introduces a method to produce metallic rare earth elements (REEs) through room-temperature electrometallization in anhydrous electrolytes. By leveraging unique ion-pairing interactions, Lewis acid-base chemistry, and interfacial structuring, the system enables efficient REE reduction and stable metal formation without the extreme energy use or toxic byproducts of conventional fused salt electrolysis. Problem Addressed High cost & regulatory barriers: Current molten-salt electrolysis (600–1200 °C) generates toxic HF gas and rare earth fluoride waste, triggering costly EPA and OSHA compliance requirements. Environmental impact: Legacy processes produce hazardous waste with long-term contamination risks, leading to industry abandonment in North America. Supply chain dependence: Metallic REEs are only produced at scale in China, creating vulnerabilities for U.S. manufacturers and defense applications. Solution The invention replaces high-temperature fused salt electrolysis with an ambient-temperature electrochemical process. The approach integrates three synergistic innovations: Tuned electrolyte nucleophilicity – enabling more efficient reduction path…
