“…The crystal structure of VO 2 will be transformed as the temperature changes and this phase change temperature is 68 °C, which leads to many kinds of VO 2 crystal forms in nature. There are mainly tetragonal VO 2 (A), monoclinic VO 2 (M), VO 2 (D), and VO 2 (B), tetragonal rutile VO 2 (R), and triclinic VO 2 (T), [ 9 ] which can have mutual transformation between them under certain conditions. Presently, a variety of vanadium dioxide polymorphs (A‐, B‐, D‐, and M‐VO 2 ) have been demonstrated to act as cathode materials for AZMB and deliverability of Zn 2+ ions storage [7b,10]…”

Rechargeable aqueous zinc metal battery has been one of the next‐generation energy storage systems with a promising future due to the advantages of aqueous electrolyte and metallic zinc anode. Among many cathode materials, vanadium‐based materials with considerable specific capacity, adjustable crystal structure, and multiple valence states are very promising cathodes, but the electrochemical performance of vanadium‐based zinc metal batteries faces severe challenges such as the limited and declining capacity and sluggish ion/e− transport kinetics process. Herein, taking VO2 as an example, the crystal structure and energy storage mechanism of VO2 cathode are briefly introduced. The challenges of aqueous Zn/VO2 battery are analyzed in depth. Significantly, the current advanced modification strategies for aqueous Zn/VO2 battery are summarized and discussed in detail, and the future development is also prospected. This article can provide some significant references for the development of aqueous Zn/VO2 battery and the guiding significance for other metal ion battery.

“…Vanadium is an important strategic metal with a vast range of applications in the metallurgical industry, chemical industry, battery, medicine, and other fields. − Currently, vanadium slag is the main direct raw material for vanadium extraction, which is the vanadium-containing tailings in the titanomagnetite steelmaking process. − The typical commercial process of vanadium recovery from vanadium slag involves sodium roasting–water leaching, the principle of which is to convert the insoluble spinel (FeV 2 O 4 , V 3+ ) in vanadium slag into soluble sodium metavanadate (NaVO 3 , V 5+ ) via full oxidation roasting; then it can be leached by water. − The leaching solution requires further purification and precipitation to prepare vanadium oxide (V 2 O 5 ) as the final product. , …”

Compared to the traditional ammonia salt method, hydrolysis for the precipitation of vanadium is a clean method that does not produce ammonia-bearing wastewater. In this study, a novel strategy of speedy acidification of static sodium vanadate (NaVO3) solution and vanadium slag leaching solution for vanadium hydrolysis was proposed to achieve high-efficiency hydrolysis by tuning the nucleation rates. The results of the parameter experiments showed that NaVO3 solution could be rapidly nucleated within 10 s and completely hydrolyzed in 30 min at a higher pH value of 2.4 and a lower temperature of 80 °C, reaching the precipitation efficiency as high as 99%. Compared to the conventional hydrolysis method, the new method could shorten the reaction time, decrease the dosage of acid, and save energy. The hydrolysis mechanism was studied by in situ focused-beam reflectance measurement and particle video microscopy, indicating that a great amount of reactant was produced because of rapid reaction when H2SO4 was all poured into the static solution. Subsequently, local high supersaturation of the reactant led to the formation of its autogenous crystal seed which resulted in red cake precipitation. In this way, the induced nucleation time of hydrolysis was shortened thereby hydrolysis and vanadium precipitation were promoted. The operation process was simple, and acid consumption, reaction time, reaction temperature, and production cost were effectively reduced, realizing high-efficiency vanadium precipitation. Finally, the kinetics of the hydrolysis process was investigated, and the chemical reaction was the rate-determining step and the apparent activation energy was found to be 50.96 kJ/mol.

“…Hybrid organic–inorganic vanadium oxides represent an attractive target owing to the relative abundance and low cost of vanadium, [33] the ease with which its multiple oxidation states can be accessed, [34] and the varied coordination geometries that vanadium centers can adopt [35–37] —implying structural tunability. Indeed, numerous examples of hybrid vanadium oxides have been reported that demonstrate the wide scope of accessible zero‐, one‐, two‐, and three‐dimensional inorganic connectivities as well as a range of organic molecules that can be included in this broad class of materials [32,37–43] .…”

We show that the conductivity of hybrid vanadium bronzes—mixed‐valence organic‐inorganic vanadium oxides—can be tuned over six orders of magnitude through judicious choice of molecular component. By systematically varying the steric profile, charge density, and propensity to hydrogen bond across a series of eight diammonium‐based molecules, we engender multiple distinct motifs of V–O connectivity within the two‐dimensional vanadium oxide layers of a family of bulk crystalline hybrid materials. A combination of single‐crystal and powder X‐ray diffraction analysis, variable‐temperature electrical transport measurements, and a range of spectroscopic methods, including UV‐visible diffuse reflectance, X‐ray photoelectron, and electron paramagnetic resonance are employed to probe how vanadium oxide layer topology correlates with electron localization. Specifically, alkylammonium molecules yield hybrids featuring more corrugated layers that contain V–O tetrahedra as well as a higher ratio of corner‐sharing to edge‐sharing polyhedra and that exhibit highly localized electronic behavior, while alkyl bipyridinium molecules yield more regular layers with polyhedral edge‐sharing that show substantially delocalized electronic behavior. This work allows for the development of design principles based on structure‐property relationships and brings the charge transport capabilities of hybrid vanadium bronzes to more technologically relevant levels.
