Ultrahigh Lithium Selective Transport in Two-Dimensional Confined Ice

“…5,8−11 This natural phenomenon has inspired the development of artificial ion-selective channels to sieve monovalent cations, 12,13 addressing the growing demand for Li + in sectors such as batteries, 14−16 glass fibers, 17 and polymers. 18,19 However, these artificial channels face challenges in selectively sieving monovalent cations due to their similar valence and affinity, alongside minimal differences in the radius of hydrated and dehydrated ions. 20−22 Two-dimensional (2D) layered materials present an ideal platform for constructing 2D capillaries as ion-selective channels, attributed to their atomically flat surface, exceptional mechanical strength, and van der Waals interactions between layers.…”

“…Selective ion transport within nanoconfined spaces is widely observed in nature, and it is critical for energy conversion and signal transduction in both biological and artificial systems. , Ion channels in biological systems, characterized by ion permselectivity, gating, and rectification effects, − facilitate selective transmembrane transport of specific ions. A notable instance is the potassium ion channel (KcsA), which exhibits a strong preference for K + over Na + , with a selectivity ratio exceeding 1000. ,− This natural phenomenon has inspired the development of artificial ion-selective channels to sieve monovalent cations, , addressing the growing demand for Li + in sectors such as batteries, − glass fibers, and polymers. , However, these artificial channels face challenges in selectively sieving monovalent cations due to their similar valence and affinity, alongside minimal differences in the radius of hydrated and dehydrated ions. − …”
