## Description

Note: This is a technology licensing opportunity. No procurement, grants, or funding opportunities are associated with this notice. 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 pathways. Lewis acid-base coordination control – stabilizing the ligand environment during deposition. Interfacial electrochemical structuring – improving reaction kinetics and metal stability. This combination allows REE electrodeposition at room temperature, reducing both energy demand and hazardous byproduct formation. This invention enables dual functionality, electrodeposition and (in-situ) electrorefining. Key Advantages Lower energy consumption – eliminates the need for 600–1200 °C molten salt processes. Reduced environmental liabilities – avoids HF gas emissions and toxic fluoride salt accumulation. Safer operations – circumvents EPA and RCRA compliance barriers tied to FSE. Domestic supply potential – enables North American REE production for critical industries. Scalable platform – adaptable to multiple REEs including neodymium, samarium, dysprosium, and terbium. Market Applications Permanent magnets – essential for EV traction motors, wind turbines, and energy-efficient refrigeration. Defense systems – critical components for satellites, communication devices, and advanced weapons. Lightweight alloys – enhancing aerospace and automotive materials. Electronics – miniaturized devices requiring REE-based components. Battery technologies – advanced REE-containing chemistries for high-performance storage.
