“…Common in situ methods include layer‐by‐layer surface assembly (LBL), interfacial polymerization (IP), cross‐linking, and atomic layer deposition . The top layer is more likely realized by in situ reactions, producing a composite membrane with closer integration of the top layer and the substrate owing to more compression and closer contact .…”

“…For instance, to achieve maximum selectivity, the N212 membrane treated with PDDA and cellulose nanocrystals (CNC) pairs required 20 bilayers [36]. Similarly, the N212 modified with polystyrene copolymer containing an azide moiety (amPS-az) and sulfonated poly(phenylene oxide) (sPPO) pairs necessitated 30 bilayers [43]. Conversely, when utilizing PFSA membranes with a thickness greater than 100 µm, such as N115, N117, and GN115, a maximum of 10 bilayers was sufficient to achieve optimum selectivity.…”

Layer-by-layer (LbL) is a widely utilized method for enhancing the selectivity, efficiency, and long-term stability of ion exchange membranes (IEMs) in various applications. This technique involves the deposition of charged thin films on IEM surface through electrostatic interactions using polycations and polyanions. The simplicity and straightforwardness of the LbL modification technique make it a preferred choice due to its reduced preparation steps and time. This method is found to be suitable for preparation of IEMs with excellent vanadium barrier properties for vanadium redox flow battery (VRFB), a battery that is highly sought to promote renewable energy to the grid level. The objective of this article provides an overview for progress in the development of IEMs for VRFB using LbL method. This includes not only description of the basics of the LbL method and its pros and cons but also factors affecting membrane functions and stability. The current applications of various LbL prepared membranes in VRFB and the challenges to their performance are pointed out. The research future directions to enhance membranes characteristics are discussed. Overall, this short review offers valuable insights into the exploration of LbL techniques for the preparation of highly selective, efficient, and stable membranes for VRFB applications.

“…Nevertheless, the Nafion membranes suffered extremely serious vanadium ion migration leading to rapid self-discharge of the battery, as well as high cost, which has impeded the commercialization of VFB . The vanadium migration of Nafion membranes could be efficiently reduced via introducing ion blockers into the clusters − or casting a vanadium-resistant ultrathin layer. − Although the modified membranes exhibit improved VFB performances, the high cost of Nafion-based membranes (500–700 $ m –2 ) still hinders the commercialization of VFB.…”

A novel amphiprotic side-chain-functionalized membrane was for the first time designed for vanadium redox flow battery (VFB). Different from frequently used blending amphiprotic membranes, the one proposed here is allowed to possess high anion-exchange capacity (IEC) without sacrificing the cation-exchange capacity (IEC) because both IEC and IEC increased with the grafting degree of side chains. Having a high IEC, the membrane prepared here exhibits an ultralow vanadium permeability (<10 cm s), which leads to very high Coulombic efficiencies (97-98% at 40-200 mA cm) of VFB and good cell self-discharge durability. Moreover, the high IEC contributes to a decent ionic conductivity (area resistance: 0.5 Ω cm), which ensures a high-voltage efficiency of the cell. On the basis of these good properties, the VFB single cell with this membrane achieves a high energy efficiency (e.g., 77.4% at 200 mA cm) that is higher than those of Nafion 212 and other reported amphiprotic membranes. These results indicate that the approach proposed here is an ideal option to prepare amphiprotic membranes for VFBs with high efficiency and good durability.
