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.

The global transition to clean energy technologies has escalated the demand for lithium (Li), a critical component in rechargeable Li-ion batteries, highlighting urgent need efficient and sustainable Li+ extraction methods. Nanofiltration (NF)-based separations have emerged as promising solution, offering selective separation capabilities that could advance resource recovery. However, an NF-based process differs significantly from conventional water treatment, necessitating paradigm shift membrane materials design, performance evaluation metrics, optimization. In this review, we first explore state-of-the-art strategies NF modifications. Machine learning was employed identify key parameters influencing efficiency, enabling rational design of high-performance membranes. We then delve into evolution transitioning traditional permeance-selectivity trade-off more relevant focus on purity recovery balance. A system-scale analysis considering specific consumption, flux distribution uniformity, is presented. review also examines integration synergistic combinations with emerging technologies, such capacitive deionization. Techno-economic lifecycle assessments are discussed provide insights economic viability environmental sustainability extraction. Finally, highlight future research directions bridge gap between fundamental practical applications, aiming accelerate development cost-effective

Multiphysics and multizone modeling of electrically switched ion exchange with self‐driven adsorption for Li⁺ extraction

AIChE Journal, Год журнала: 2025, Номер unknown

Опубликована: Фев. 11, 2025

Abstract Electrically switched ion exchange (ESIX) is a promising approach for extracting Li + from brines with high Mg/Li ratios. However, the effect of operating conditions and film electrode parameters on electrochemical performance remains unclear. Herein, dynamic multiphysics multizone model was developed to describe ESIX process self‐driven adsorption, using an LMO/PPy pair charge transport. The results revealed that flow velocity 0.0125 m/s PPy/LMO mass ratio 15:1 can effectively reduce concentration polarization activate electroactive sites, respectively. Additionally, solid volume fraction LMO particles increases difference thereby enhancing extraction performance. Meanwhile, low currents (≤25 mA/g) narrow gap between interfacial current applied current, hence improving efficiency. This serves as efficient in‐silico tool designing optimizing processes.
