“…In this case, the issue of separation of mono- and divalent ions is becoming more and more important [ 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ]. For example, membrane separation of lithium and magnesium or cobalt ions [ 43 , 44 , 45 , 46 , 47 ] and the removal of magnesium/calcium [ 48 , 49 , 50 , 51 ] have attracted increasing attention. On the contrary, membranes in fuel cells are usually in single ionic form (H + or OH − -form) and contact only with humidified gases or methanol.…”

Membrane technologies are widely demanded in a number of modern industries. Ion-exchange membranes are one of the most widespread and demanded types of membranes. Their main task is the selective transfer of certain ions and prevention of transfer of other ions or molecules, and the most important characteristics are ionic conductivity and selectivity of transfer processes. Both parameters are determined by ionic and molecular mobility in membranes. To study this mobility, the main techniques used are nuclear magnetic resonance and impedance spectroscopy. In this comprehensive review, mechanisms of transfer processes in various ion-exchange membranes, including homogeneous, heterogeneous, and hybrid ones, are discussed. Correlations of structures of ion-exchange membranes and their hydration with ion transport mechanisms are also reviewed. The features of proton transfer, which plays a decisive role in the membrane used in fuel cells and electrolyzers, are highlighted. These devices largely determine development of hydrogen energy in the modern world. The features of ion transfer in heterogeneous and hybrid membranes with inorganic nanoparticles are also discussed.

“…Recently, increasing attention has been paid to the separation and processing of complex mixtures, including industrial and domestic wastes, sea water [ 39 , 40 , 41 , 42 , 43 , 44 , 45 ]. There is every reason to believe that their processing, along with recycling, would determine a major part of production of a number of metals and their compounds [ 39 , 46 , 47 , 48 , 49 , 50 ]. For the development of such technologies the selectivity between ions with different valences of the same sign (mono- and multivalent) is no less important [ 51 , 52 , 53 , 54 ].…”

Nowadays, ion-exchange membranes have numerous applications in water desalination, electrolysis, chemistry, food, health, energy, environment and other fields. All of these applications require high selectivity of ion transfer, i.e., high membrane permselectivity. The transport properties of ion-exchange membranes are determined by their structure, composition and preparation method. For various applications, the selectivity of transfer processes can be characterized by different parameters, for example, by the transport number of counterions (permselectivity in electrodialysis) or by the ratio of ionic conductivity to the permeability of some gases (crossover in fuel cells). However, in most cases there is a correlation: the higher the flux density of the target component through the membrane, the lower the selectivity of the process. This correlation has two aspects: first, it follows from the membrane material properties, often expressed as the trade-off between membrane permeability and permselectivity; and, second, it is due to the concentration polarization phenomenon, which increases with an increase in the applied driving force. In this review, both aspects are considered. Recent research and progress in the membrane selectivity improvement, mainly including a number of approaches as crosslinking, nanoparticle doping, surface modification, and the use of special synthetic methods (e.g., synthesis of grafted membranes or membranes with a fairly rigid three-dimensional matrix) are summarized. These approaches are promising for the ion-exchange membranes synthesis for electrodialysis, alternative energy, and the valuable component extraction from natural or waste-water. Perspectives on future development in this research field are also discussed.

“…and OH -; therefore, H ? and OHcan be combined with other ions in solution [213,225]. The results show that after ED treatment of a Li 2 CO 3 feed solution using a bipolar membrane, the purity of the obtained LiOH can reach 95% [224].…”

“…In the presence of an electric potential difference, cations and anions can directionally migrate through the selective ion exchange membrane with ion-selective permeability, thereby separating and concentrating ions. Figure 16a displays a schematic of the migration process [213], in which cations migrate toward the cathode, while anions migrate toward the anode. Cations can easily pass through the negatively charged cation exchange membrane, while anions can easily pass through the positively charged anion exchange membrane.…”

Rapid developments in the electric industry have promoted an increasing demand for lithium resources. Lithium in salt lake brines has emerged as the main source for industrial lithium extraction, owing to its low cost and extensive reserves. The effective separation of Mg 2? and Li ? is critical to achieving high recovery efficiency and purity of the final lithium product. This paper summarizes Mg 2? /Li ? separation materials and methods in the field of lithium recovery from salt lake brines. The review begins with an introduction to the global distribution and demand for lithium resources, followed by a description of the materials used in various separation techniques, including precipitation, adsorption, solvent extraction, nanofiltration membrane, electrodialysis, and electrochemical methods. A comparison, analysis, and outlook of such methods are comprehensively discussed in terms of principles, mechanisms, synthesis/operation, development, and industrial applications. We conclude with a presentation of challenges and insights into the future directions of lithium extraction from salt lake brines. A combination of the advantages of various materials is the most logical step toward developing novel methods for extracting lithium from brines with high separation selectivity, stability, low cost, and environmentally friendly characteristics.
