Resumen de: US20260062305A1
Systems and methods for obtaining lithium-containing materials from liquid streams are generally described. In some instances, aqueous streams are treated with a lithium selective agent prior to and/or following electrolysis of the stream to produce basic species such as hydroxide ions. In some cases, the lithium selective agent is a solids-forming agent such as a precipitant (e.g., phosphoric acid/phosphate) or a solid sorbent (e.g., aluminum hydroxide). The electrogenerated basic species may induce carbon dioxide capture to form carbonate and/or bicarbonate anions. Coupling of the electrolytic processes and/or carbon dioxide capture processes to the lithium selective separation processes may promote efficient generation of value-added lithium-containing materials such as lithium hydroxide and/or lithium carbonate. Some embodiments involve the electrolytic and/or thermal regeneration of the lithium selective agent, and/or the recycling of electrogenerated acidic species, which can also contribute to an efficient, cost-effective system for obtaining lithium-containing materials.
Resumen de: US20260062293A1
When producing lithium sulfide by a reaction between a lithium raw material and hydrogen sulfide, the reaction is performed under relatively mild conditions compared to the conventional technology, so frequent repairs or replacements due to corrosion and breakdown of reactors and piping are not required, thereby improving the economic efficiency of the process. Since unreacted hydrogen sulfide and a solvent from which moisture has been removed are reused, process costs are reduced so that economic feasibility in mass production is ensured. Furthermore, moisture and water vapor generated in a lithium sulfide production reaction are effectively removed to prevent a reverse reaction into lithium hydroxide and promote a forward reaction so that high-quality lithium sulfide can be produced with high purity and high yield. In addition, particle size may be controlled in the micrometer range without a separate crushing space or crushing stage, thereby providing excellent convenience and mass production.
