“…Researchers from the same group also investigated the performance of the quaternized poly(phthalazinone ether ketone) (QBPPEK) anion exchange membranes for VRFBs. 50 The obtained membrane performs 75 comparable water uptake and similar area resistance to the Nafion117. Since the quaternary groups hold positive charges and prevent vanadium ions from entering the membrane, the mass transfer coefficient of vanadium ions in QBPPEK is about 5 times smaller compared with Nafion117.…”

“…39 The 45 mechanical strength of the membranes amplifies proportionally with the content of P(VDF-co-HFP), while vanadium ion permeability diminishes. Although the CE, VE and EE of VRFBs assembled with SFPAE/10%P(VDF-co-HFP) and SFPAE are similar, the cell lifetime of the composite membrane is improved 50 by 44% comparing to pristine SFPAE. This may be due to the reinforcement effect of the P(VDF-co-HFP) in the blend.…”

“…48 Membrane resistance values of APS and AFN are relatively small and slightly change when soaking in VO 2 + solution. On the other hand, use of AHA 50 leads to larger membrane resistance and significant change of membrane resistance during the soaking process. VRFBs using AFN membrane have constant cell resistances with different states of charge (SOC) and different states of discharge (SOD), respectively.…”

“…3 Thus, many research groups all over the world focus on investigating, finding and developing the right membrane for VRFBs, which provides good performance but low cost. Although there are excellent reviews 50 about VRFBs 1,2 and membranes for VRFBs, 3,8,9 there are about 100 papers published in the last two years which were not covered in any reviews. More important, we can see a new research trends which focus on developing anion-exchange or other types of polymer membranes rather than only modifying 55 Nafion or developing cation-exchange membranes, which dominated the literature in the previous years.…”

“…On the other hand, Kim et al investigated the properties of sulfonated graphene oxide (sGO)/Nafion composite membranes in VRFBs. 25 In order to 50 promote miscibility with Nafion, sGO was treated with phenyl isocyanate to form isGO.

The all-vanadium redox flow battery (VRFB) is one of the most promising energy storage systems to be associated with the grid. The system has been developed for almost 30 years. A key component for VRFBs is the membrane separator, which separates the positive and negative half-cells and prevents the cross-mixing of vanadium ions, while providing required ionic conductivity. In general, research is to solve a multi-variable problem which requires optimization in both physical characteristics and electrochemical performance of the 10 membrane. Nafion and its derivatives are still important materials thanks to their high chemical stability and ionic conductivity. However, weaknesses of these materials, such as high vanadium ion crossover and high cost, stimulate new approaches in materials design for VRFBs. New achievements in material sciences and polymer chemistry allow further development of other types of polymeric materials and composites as separators in VRFBs. This includes new cation exchange membranes, anion exchange membranes, amphoteric 15 ion-exchange membranes, and non-ionic porous materials. Each type of material exhibits its advantages, accompanying with its weaknesses. Recent articles in polymer-containing membranes for use as separators in VRFBs are reviewed.Journal Name, [year], [vol], 00-00 | 5 vanadium crossover in s-Radel in comparison with that in Nafion.

Over the past three decades, intensive research activities have focused on the development of electrochemical energy storage devices, particularly exploiting the concept of flow batteries. Amongst these, vanadium redox flow batteries (VRFB) are an attractive option, which have been studied extensively and are now being commercialized around the world. The performance of the VRFB system is governed by several critical components namely the electrolyte, the electrode, the ion‐exchange membrane and the flow field design. Here, the focus is mainly on recent research activities relating to the development and modification of electrode materials and new ion‐exchange membranes. The feasibility of novel flow field designs for high energy density VRFB systems and their future prospects are also discussed in detail.

IntroductionWith the rapid increase of consumption of fossil fuels and the consequent environment pollution, there is an urgent need for the development and effective utilization of renewable energy sources like wind, solar, biomass, etc. However, these renewable energy sources are intermittent in nature, leading to the conflict between the seasonal and unstable electricity generation and requirement of the continuous and stable power supply for the end application. Thereby, energy storage Vanadium redox flow batteries (VRFBs) are regarded as one of the most promising electrochemical technologies for grid-connected renewable energy storage systems. The performance of VRFBs, however, strongly depends on the membrane, one of the key components of VRFBs with critical dual functions of promotion of diffusion of active species (H + , H 3 O + , SO 4 2−, or SO 4 H − ) and inhibition of crossover of vanadium ions. This is intrinsically related to the microstructure of membranes. For example, large and connected ionic clusters or pores in membranes are favorable for the ion transfer, but detrimental to the ion selectivity. While small and isolated hydrophilic ion clusters or pores suppress the water uptake and ion transfer, the decreased swelling ratio would enhance chemical stability of membrane. Thus, comprehensive strategies are required to realize the optimal balance between the ion selectivity, proton conductivity, and chemical stability. This review focuses on the effects of microstructure of membranes on the ion transfer and the chemical stability, including introduction of the rigid groups, electron-withdrawing groups, and hydrophobic backbones, are reviewed. The prospect of the development of membranes with high ion selectivity and high-performance VRFBs is discussed.
