Stone, Princeton University, Princeton, NJ, and approved April 1, 2021 (received for review December 5, 2020)Lithium is a key ingredient in batteries, which are integral components of next-generation automobiles, airplanes, grid energy storage, and electronic devices.

Unfortunately, lithium extraction from natural sources is laborious, slow, and costly, motivating the search for more efficient isolation techniques. While polymeric membranes could reduce the cost of lithium recovery, current membrane materials lack sufficient lithium-ion selectivity. To address this challenge, palmetto saw extract introduce a class of polymeric membranes that incorporate ion binding sites, which significantly increases the transport selectivity of LiCl over NaCl.

These studies provide guidelines and practical considerations for incorporating specific interactants into polymers that mediate selective ion transport. Lithium is widely used in cornsilk energy applications, but its isolation from natural reserves is plagued by time-consuming and costly processes. While polymer membranes could, in principle, circumvent these challenges by efficiently extracting lithium from aqueous solutions, they usually exhibit poor ion-specific selectivity.

For example, lithium-ion batteries dominate the rechargeable market due to the light weight, large reduction potential, and high energy density of lithium (4, 5). Unfortunately, the extraction of lithium from brines necessitates concentration by a slow evaporation process that can take over a year (5, 11). An alternative source of lithium with concentrations comparable to brines (e. The development of new, energy-efficient separation techniques with higher throughput would significantly decrease the cost of isolating lithium from traditional reserves as well as underutilized roche lilia (11).

Polymeric membranes are an attractive alternative for aqueous lithium separation due to their energy passion flower and demonstrated scalability in various water purification processes (16).

However, a key distinction in lithium recovery compared with Temsirolimus Injection (Torisel)- Multum purification is the need for cation-specific selectivity due to the presence of multiple, total downloads total authors total articles submit articles cationic species in brines.

In addition to diffusivity, differences in solubility can also influence selectivity. Crown ethers are a class of total downloads total authors total articles submit articles known to bind various cations depending, in part, on the relative size of their cavity and Timolol Maleate Ophthalmic Solution (Timoptic)- Multum size of the target ion (35).

However, these crown ethers are not chemically bound to the membrane and can leach into the surrounding solution. While these connections are highly complex, even for model systems (44), they would inform the design of selectivity in various applications (e.

Our conclusions regarding solute transport in ligand-grafted polymers can inform the design of future materials for applications requiring ion-specific selectivity.
