“…Based on the electroactive species solvents, it can be classified as a non-aqueous redox flow battery, an aqueous redox flow battery, and a hybrid aqueous/non-aqueous redox flow battery [45][46][47][48]. More interestingly, the RFB has been further classified based on their electroactive species (redox couple) presence in the electrolyte solution such as Hydrogen/Bromine [49], Iron/Chromium [50], Vanadium/Bromine [51], Zinc/Bromine [52], All-Vanadium [53,54], Vanadium/Polyhalide [55], Zinc/Cerium [56], Iron/Vanadium [57], Tin/Bromine [58], Polysulfide/Bromine [59], vanadium/Manganese [60], Cerium/Lead [61], Soluble Pb [62], Zinc/Polyiodide [63], aqueous organic [64,65], and non-aqueous organic RFBs [66,67].…”

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.

“…Ajeya et al proposed the use of organic ligands to treat spent VOSO 4 to obtain a vanadium-containing electrolyte, whose performance is comparable to that of commercial electrolytes. [61] Liu et al employed sodium polyvanadate precipitated wastewater as raw material to prepare VFB electrolyte through solvent extraction two-stage purification, and its performance is close to that of conventional electrolyte. [62] Spent electrolyte can also be used to prepare vanadium pentoxide.…”

Metal-ion batteries have emerged as promising candidates for energy storage system due to their unlimited resources and competitive price/performance ratio. Vanadium-based compounds have diverse oxidation states rendering various openframeworks for ions storage. To date, some vanadium-based polyanionic compounds have shown great potential as highperformance electrode materials. However, there has been a growing concern regarding the cost and environmental risk of vanadium. In this Review, all links in the industry chain of vanadium-based electrodes were comprehensively summarized, starting with an analysis of the resources, applications, and price fluctuation of vanadium. The manufacturing processes of the vanadium extraction and recovery technologies were discussed. Moreover, the commercial potentials of some typical electrode materials were critically appraised. Finally, the environmental impact and sustainability of the industry chain were evaluated. This critical Review will provide a clear vision of the prospects and challenges of developing vanadium-based electrode materials.

“…And the peak of V2p 3/2 (517.16 eV) shifts slightly to left compared with the standard peak of VO 2 + (516.20 eV), suggesting vanadium binds with oxygen groups on GO (Figure S4). [44] In addition, the characteristic X-ray crystal diffraction (XRD) peak of the GO (Figure S5) shows a small right shift after adsorption, possibly because of the decreased interlayer spacing of the GO induced by the interaction with V(IV). [45,46] The isothermal adsorption data were subjected to the Temkin model (R 2 = 0.902-0.933, Figure 4b), Freundlich model (R 2 = 0.798-0.910, Figure 4c) and Langmuir model (R 2 = 0.690-0.916, Figure 4d) to further analyze the adsorption isotherm (Table S1).…”

Vanadium is a long-confined contaminant. In this study, graphene oxide (GO) was synthesized by the modified Hummers' method and used to remove vanadium(IV). The adsorption isotherms and kinetics of vanadium(IV) on GO at pH 2.5 and three temperatures are measured in batch experiments. The influences of ionic strength is investigated and the regeneration of GO is evaluated by washing with HCl. The results show that the adsorption isotherm corresponds to Temkin model with an adsorption capacity of 70.56 mg/g at 298 K, while the kinetic process coincides with pseudo-secondorder model and approaches to equilibrium in 6 h. The adsorption capacity of GO is not influenced by Na + ionic strength, but sharply inhibited by Ca 2 + . The superior adsorption is dominated by electrostatic interaction, coordination bonding, and hydrogen bonding. Moreover, the GO is reusable, as shown by maintaining 53.4 % of the initial efficacy after five sequential adsorption-desorption cycles.
