Lithium mining is energy intensive and environmentally costly. This because lithium ions are typically present in brines as a minor component mixed with physiochemically similar cations that difficult to separate. Inspired by nature’s ability selectively extract species transpiration, we report solar transpiration–powered extraction storage (STLES) device can store from using natural sunlight. Specifically, the uses hierarchically structured transpirational evaporator create pressure gradient, which allows for of through membrane its vascular layer. Long-term experiments, various tests, different size assessments demonstrate stability, compatibility, scalability STLES. solar-powered technology provides an alternative developing pathway toward sustainable critical resources.

Membrane Design Principles for Ion-Selective Electrodialysis: An Analysis for Li/Mg Separation

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Published: Feb. 7, 2024

Selective electrodialysis (ED) is a promising membrane-based process to separate Li+ from Mg2+, which the most critical step for Li extraction brine lakes. This study theoretically compares ED-based Li/Mg separation performance of different monovalent selective cation exchange membranes (CEMs) and nanofiltration (NF) at coupon scale using unified mass transport model, i.e., solution-friction model. We demonstrated that CEMs with dense surface thin film like polyamide are more effective in enhancing than those loose but highly charged film. Polyamide film-coated when used ED have similar polyamide-based NF NF. membranes, expected replace separation, will require support layer low tortuosity high porosity reduce internal concentration polarization. The coupon-scale analysis comparison provide new insights into design composite ion–ion separation.

Recent advances of thin film composite nanofiltration membranes for Mg2+/Li+ separation

Advanced Membranes, Journal Year: 2024, Volume and Issue: 4, P. 100093 - 100093

Published: Jan. 1, 2024

The prevalent adoption of lithium-ion batteries (LIBs) has sparked a surge in interest regarding lithium extraction, particularly from lithium-rich brines. As some brine sources contain higher ratio Mg2+ ions to Li + ions, Mg2+/Li+ separation becomes essential improve extraction efficiency. Multiple membrane technologies were utilized this application, including electrodialysis, capacitive deionization, and nanofiltration (NF). Among the different technologies, NF membranes fabricated through interfacial polymerization have gained interdisciplinary attention due their ease modification, relative simplicity, cost-effectiveness. Despite that, there are still multiple challenges Mg2+/Li such as high (MLR), trade-off between factor pure water permeance (PWP), fouling, optimal working pH. To address these challenges, review summarizes nanofillers used enhance performance, carbon-based nanofillers, polyphenols, polyhedral oligomeric silsesquioxane (POSS). Additionally, categorized based on modification polymerization, types aqueous monomer, addition phase, substrate, an extra layer within membrane, other modifications. Lastly, perspectives factors that affect performance surface zeta potential, pore size, hydrophilicity, feed pH, MLR will be discussed. It is anticipated comprehensive can provide insights into current progress various strategies drive future research development using technology among community.
