Abstract High performance polyamide nanofiltration membranes play important roles in Mg 2+ /Li + separation and Li extraction, but they are prepared via multiple time‐/labor demanding steps. Both the scalability of these engineering membrane modules remain an elusive challenge. Here design a Gemini‐electrolyte monomer (GEM) featuring bidentate amine groups, quaternary ammonia, endocyclic contorted conformation is reported. The monomer's low interfacial diffusivity balanced by high condensational reactivity during its polymerization with trimesoyl chloride (TMC), leading to straightforward formation defect‐free, ≈14 nm thick membranes. shows highest permeance (≈19.2 L m −2 h −1 bar ) among without post‐modification, combined good selectivity (≈15.4) stability. validity GEM verified control monomers.

Nanofiltration (NF) is a promising and sustainable process to extract Li+ from brine lakes with high Mg2+/Li+ mass ratios. However, trade-off between Li/Mg selectivity Li recovery exists at the scale, of commercially lab-made NF membranes in single-pass insufficient achieve industrially required purity. To overcome this challenge, we propose multipass recirculation without sacrificing recovery. We experimentally demonstrate that three-pass commercial membrane can exceed 1000, despite compromised as result co-existing cations. Our theoretical analysis further predicts four-pass simultaneously an ultrahigh over 4500 95%. This proposed could potentially facilitate efficient NF-based solute-solute separations all kinds contribute development novel membrane-based separation technologies.

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.

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.
