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.

Abstract Membranes facilitate scalable and continuous lithium concentration from hypersaline salt lakes battery leachates. Conventional nanofiltration (NF) membranes, however, exhibit poor monovalent selectivity in high‐salinity environments due to weakened exclusion mechanisms. This study examines polyamide NF membranes coated with polyelectrolytes enriched ammonium groups maintain high cation conditions. Over 8000 ion rejection measurements are recorded using lake brines The experiments exemplify the membrane's ability reduce magnesium concentrations 0.14% elevate purity 98% leachates, a single filtration stage. is retained after 12 weeks acidic Molecular dynamics analyses reveal that create an electrostatic barrier at low pH, selectively hindering multivalent transport. corroborated by Coulombic attraction between cations carboxylate groups, along repulsive groups. Despite 14.7% increase specific energy, two‐stage system for recovery significantly reduces permeate composition 0.031% Chilean brines. For NMC achieve exceeding 99.5%, yielding enhanced quality minor increases energy demands.
