“…Moreover, the hydroxyl group in the carbohydrate provided more active sites for the redox reaction of VRB, and effectively improves the low temperature stability of the negative electrolyte. Wei et al 92 used zwitterion molecules containing sulfonic and pyridine groups as additives to effectively improve the performance of VRB positive electrolyte. And then Wei 93 presented the potassium diformate could significantly improve the electrochemical activity and battery cycle stability.…”

Vanadium electrolyte is one of the most critical materials for vanadium redox batteries (VRB). Reducing the cost of vanadium electrolyte and improving its performance are ongoing research priorities for VRB. Currently, the control of the cost of vanadium electrolyte mainly relies on the development of new processes and optimization of traditional processes. Improving the performance of electrolytes mainly involves two aspects: mass transfer and charge transfer, such as introducing additives, optimizing supporting electrolytes, and developing new electrode catalysts. This article reviews the progress in improving the performance of VRB in the past 10 years. It focuses on three main aspects: the preparation of electrolytes, the influence of mass transfer on battery performance, and the influence of charge transfer on battery performance. It also further discusses the impact of different factors on the improvement of VRB performance. Finally, it summarizes the challenges faced by VRB in performance improvement and commercial applications, and made suggestions for future research and development of VRB.

“…This modifying behavior to electrodes can activate the interfacial activity between electrodes and the electrolyte, accelerating both the redox reaction of vanadium ions in all valences and the migration mass transfer. Alternatively, additives, such as taurine, MSA, PPS, benzoyl peroxide, and so on, can reduce the overpotential of the VRFB to facilitate the migrating mass transfer, reducing the resistance of the electric double layer and enhancing the kinetics of redox reactions [ 56 , 57 , 58 , 59 , 60 ].…”

“…It has been demonstrated, as shown in Table 2 , Table 3 , Table 4 and Table 5 , that organic additives such as pyridinium propyl sulfobetaine (PPS), ammonium acetate, 1-hydroxyethane-1,1-diphosphonic acid (HEDP), acidic amino acids, and organophosphorus compounds, can effectively lengthen the precipitation time and widen the temperature range of the vanadium electrolyte [ 31 , 44 , 53 , 59 , 79 , 89 , 90 ]. For example, PPS was able to delay the induction time for precipitation by an average of 3–6 h at 50 °C [ 59 ]. The addition of 1 wt% HEDP could extend the temperature range of the electrolyte from 0–25 °C to 0–40 °C without influencing the electrochemical activity and cell efficiency.…”

Vanadium redox flow batteries (VRFBs) are promising candidates for large-scale energy storage, and the electrolyte plays a critical role in chemical–electrical energy conversion. However, the operating temperature of VRFBs is limited to 10–40 °C because of the stability of the electrolyte. To overcome this, various chemical species are added, but the progress and mechanism have not been summarized and discussed yet. This review summarizes research progress on electrolyte additives that are used for different purposes or systems in the operation of VRFBs, including stabilizing agents (SAs) and electrochemical mass transfer enhancers (EMTEs). Additives in vanadium electrolytes that exhibit microscopic stabilizing mechanisms and electrochemical enhancing mechanisms, including complexation, electrostatic repulsion, growth inhibition, and modifying electrodes, are also discussed, including inorganic, organic, and complex. In the end, the prospects and challenges associated with the side effects of additives in VRFBs are presented, aiming to provide a theoretical and comprehensive reference for researchers to design a higher-performance electrolyte for VRFBs.

“…The performance of VRFB can be altered by employing the co-solvents and different kinds of additives in the electrolyte solution for boosting the steadiness, electroactive species solubility, and overall electrochemical performances. Different kinds of additives have been utilized as stabilizing agents such as zwitterion-type molecule (pyridinium propyl sulphobetaine with sulfonic and pyridine groups), inositol or phytic acid, Trishydroxymethyl aminomethane, Polyacrylic acid, l-glutamic acid, antimony ions, sodium formate, methanesulfonic acid, K 2 SO 4 , Li 2 SO 4 , KHSO 4 , Na 2 SO 4 , CH 3 SO 3 H, MgCl 2 for different oxidation states of vanadium ions [74][75][76][77][78][79][80][81]. In VRFB, the bipolar plate serves as a multifunctional component for constructing and operating the unit cell system [82][83][84].…”

In recent years, vanadium redox flow batteries (VRFB) have captured immense attraction in electrochemical energy storage systems due to their long cycle life, flexibility, high-energy efficiency, time, and reliability. In VRFB, polymer membranes play a significant role in transporting protons for current transmission and act as barriers between positive and negative electrodes/electrolytes. Commercial polymer membranes (such as Nafion) are the widely used IEM in VRFBs due to their outstanding chemical stability and proton conductivity. However, the membrane cost and increased vanadium ions permeability limit its commercial application. Therefore, various modified perfluorinated and non-perfluorinated membranes have been developed. This comprehensive review primarily focuses on recent developments of hybrid polymer composite membranes with inorganic TiO2 nanofillers for VRFB applications. Hence, various fabrications are performed in the membrane with TiO2 to alter their physicochemical properties for attaining perfect IEM. Additionally, embedding the -SO3H groups by sulfonation on the nanofiller surface enhances membrane proton conductivity and mechanical strength. Incorporating TiO2 and modified TiO2 (sTiO2, and organic silica modified TiO2) into Nafion and other non-perfluorinated membranes (sPEEK and sPI) has effectively influenced the polymer membrane properties for better VRFB performances. This review provides an overall spotlight on the impact of TiO2-based nanofillers in polymer matrix for VRFB applications.
