摘要： This invention presents an electrochemical metallurgical technique for extracting metals and sulfur from metal sulfides, offering an adjustable composition and mechanical properties during electrode preparation. The metal sulfide anode, submerged in an electrolyte with a cathode made of materials like titanium, copper, stainless steel, lead, zinc, aluminum or graphite, undergoes electrolysis. This process oxidizes sulfur in the metal sulfide to the anode and releases metal ions into the electrolyte, where they're reduced at the cathode. The method yields metal at the cathode and sulfur at the anode, with minimal environmental impact, low investment, and straightforward process.

摘要： The presently disclosed concepts relate to green battery recycling systems and critical mineral reclamation and refinement. Alkali metal extraction (and in particular lithium extraction) is accomplished using a solid electrolyte membrane in combination with electrodes in a redox configuration. The energy used to initially extract lithium from a feed solution is stored as electrochemical energy, which electrochemical energy is reclaimed in subsequent reclamation processing steps. This reclamation may further allow for lithium to be converted to lithium carbonate or lithium hydroxide, or purified to a minimum purity of 99.9% lithium by mass. These extraction and reclamation steps may performed in continuous ultra-efficient ongoing cycles. Since irrecoverable energy losses incurred in each cycle are limited to negligible amounts of joule heating of the system components and feed solution, the system can be sustainably powered using locally-generated renewable energy, which in turn, provides for a green and sustainable solution for lithium recycling.

摘要： A decoupled plating system is provided for producing lithium. In a general embodiment, the present disclosure provides a feed tank configured to supply a lithium-rich aqueous electrolyte stream, a plating tank that is configured to receive an organic electrolyte and plate out lithium metal from that organic electrolyte, and one or more lithium replenishment cells configured to receive both electrolytes, keep them separated, and selectively move lithium ions from the aqueous electrolyte into the spent organic electrolyte stream. The present system and process can advantageously reduce operating costs and/or improve energy efficiency in production of lithium metal and associated products.

摘要： The presently disclosed concepts relate to improved techniques for alkali metal extraction (and in particular lithium), using a solid electrolyte membrane. By using a solid electrolyte embedded in a matrix, alkali metal (such as lithium) can be more effectively separated from feed solutions. Additionally, energy used to initially extract lithium from a feed solution may be stored as electrochemical energy, which in turn, may be discharged when lithium is depleted from the electrode. This discharged energy may therefore be reclaimed and reused to extract additional lithium.

摘要： A process of producing metal that includes adding a quantity of a alkoxide (M(OR)x) or another metal salt to a cathode compartment of an electrolytic cell and electrolyzing the cell. This electrolyzing causes a quantity of alkali metal ions to migrate into the cathode compartment and react with the metal alkoxide, thereby producing metal and an alkali metal alkoxide. In some embodiments, the alkali metal is sodium such that the sodium ions will pass through a sodium ion selective membrane, such as a NaSICON membrane, into the cathode compartment.

摘要： Alkali metals and sulfur may be recovered from alkali monosulfide and polysulfides in an electrolytic process that utilizes an electrolytic cell having an alkali ion conductive membrane. An anolyte includes an alkali monosulfide, an alkali polysulfide, or a mixture thereof and a solvent that dissolves elemental sulfur. A catholyte includes molten alkali metal. Applying an electric current oxidizes sulfide and polysulfide in the anolyte compartment, causes alkali metal ions to pass through the alkali ion conductive membrane to the catholyte compartment, and reduces the alkali metal ions in the catholyte compartment. Liquid sulfur separates from the anolyte and may be recovered. The electrolytic cell is operated at a temperature where the formed alkali metal and sulfur are molten.
