“…Also, it can be seen that the crystal structure of pure V 2 O 5 has the strongest intensity of the (0 0 1) plane at 2θ = 20.40°, with a d-spacing of 4.34 Å, while V 2 O 5 /S composite has the same peak with a dspacing of 4.35 Å. It was confirmed that small ratio of sulfur expanded the interlayer spacing of V 2 O 5 in (0 0 1) direction, shielded the powerful polarization effect of divalent Mg 2+ ions and could facilitate the intercalation process of Mg 2+ ions [23]. The sulfur insertion succeeded in expanded interplanar distance of (0 0 1) plane from 4.34 Å to 4.35 Å.…”

Magnesium batteries are regarded as promising candidates for energy storage devices owing to their high volumetric capacity. The practical application is hindered, however, by strong electrostatic interactions between Mg 2+ and the host lattice and due to the formation of a passivation layer between anode and electrolyte. V 2 O 5 is a typical intercalation compound with a layered crystal structure ((0 0 1) interlayer spacing ∼ 11.53 Å), which can act as a good host for the reversible insertion and extraction of multivalent cations. Herein, we have presented an investigation of the effects of S injection on the structure, electrochemical performance and Mg 2+ diffusion in V 2 O 5 cathode materials for Mg-ion batteries. The V 2 O 5 /S composite structure was investigated using X-ray diffraction, field-emission scanning electron microscope and energy dispersive X-ray spectroscopy. The integrated electrode exhibits an improvement in the electrical and electrochemical properties compared to the V 2 O 5 electrode. The as-prepared V 2 O 5 /S composite has an initial discharge capacity of 310 mAh·g −1 compared to 160 mAh·g −1 for the V 2 O 5 electrode. The V 2 O 5 /S composite is a promising cathode material for magnesium-ion battery applications.

“…Due to the natural abundance and multiple oxidation states of vanadium, V‐based compounds, especially vanadium oxides, have been widely used as electrode materials for batteries and supercapacitors . To date, various kinds of vanadium‐based materials, such as VO 2 , V 2 O 5 , VS 2 , H 2 V 3 O 8 , Na super ionic conductors (NASICONs) structured Na 3 V 2 (PO 4 ) 3 , lithium vanadium oxide, silver vanadium oxide, sodium vanadium oxide, zinc vanadium oxide, potassium vanadates, calcium vanadium oxide bronze, and iron vanadate, have been explored as cathodes for ZIBs due to the high capacity, good rechargeability, and long electrochemical stability (compared to Mn‐based cathode).…”

the developing trend of modern electronic technologies, [6] and significant efforts have been devoted to transforming these energy storage systems to their light, flexible, small, and thin counterparts. [7] The flexible battery market is forecast to increase rapidly from $69.6 million in 2015 to $958.4 million in 2022. [8] Lithium-ion batteries (LIBs) historically and presently dominant the markets of rechargeablebattery for portable devices because of the lightness of lithium and high energy density of the battery systems. [9,10] Nonetheless, LIBs are marred by the high cost and the shortage of lithium resources. Moreover, the aprotic electrolytes used in LIBs are generally toxic and flammable. This fact causes great safety issues for LIBs, especially when they are used in wearable/implantable applications in close contact with human body. It is highly challenging to assemble flexible LIBs due to the requirement of a highly reliable protective packaging to avoid the electrolyte leakage and reconcile with the washing need of wearable devices in practical applications. [3] Moreover, due to the high barrier encapsulation, the volumetric performance would be severely restricted, especially when LIBs are miniaturized. In this context, it is highly desirable to prepare flexible "beyond Li-based" batteries with safe, low-cost, and eco-friendly aqueous electrolytes. [11] As alternatives for LIBs, multivalent ion battery technologies (Zn-ion battery, ZIB, Mg-ion battery, and Al-ion battery) are of high interest for electrochemical energy storage. In comparison with LIBs operating with single-electron transfer, multivalent ion batteries employ multielectron transfer during the charge/ discharge processes, thus delivering much higher volumetric energy densities. [12][13][14] Since the first utilization of Zn in batteries in 1799, [15] Zn metal has captured increasing attention as an ideal anode material. In earlier studies, Zn anodes were widely explored in many alkaline battery systems, such as alkaline zinc-MnO 2 batteries, [16] zinc-nickel batteries, [17][18][19][20] zinc-silver batteries, [21] and zinc-air batteries. [22][23][24] Zn metal is able to offering both high gravimetric and high volumetric capacities (820 and 5855 mAh cm −3 ). [25] Moreover, Zn has the merits of low cost, low-toxicity, abundance in earth crust (≈300 times higher than for lithium), environmental benignity, easily recyclable, and intrinsic safety. [14,26] These advantages directly drove the recent renaissance of Zn anode based batteries. [15] However, the use of corrosive alkaline electrolyte leads to the Zn-dendritic (sharp, needle-like metallic protrusions) growth [27,28] and soluble ZnO 2 2− formation on Zn anode, which poison the cathode and result in the rapid capacity To keep pace with the increasing pursuit of portable and wearable electronics, it is urgent to develop advanced flexible power supplies. In this context, Zn-ion batteries (ZIBs) have garnered increasing attention as favorable energy storage devices for flexible electronics, ...

“…The possible reason responsible for capacity decay could be attributed to unwanted side reaction 54 , for example, the dissolution of electrode materials V2O5 [55][56] , a small contribution of structural irreversibility of V2O5. The "capacity match" between cathode and anode materials might also play an important role in an "unideal state" 54 .…”

Orthorhombic V2O5 nanowires were successfully synthesized via a hydrothermal method. A cellconfiguration system was built utilizing V2O5 as the cathode and 1 M Mg(ClO4)2 electrolyte within acetonitrile, together with MgxMo6S8 (x ≈ 2) as the anode to investigate the structural evolution and oxidation state and local structural changes of V2O5. The V2O5 nanowires deliver an initial discharge/charge capacity of 103 mAh g-1 /110 mAh g-1 and the highest discharge capacity of 130 mAh g-1 in the 6 th cycle at C/20 rate in the cell-configuration system. In operando synchrotron diffraction and in operando X-ray absorption spectroscopy together with ex situ Raman and X-ray photoelectron spectroscopy reveal the reversibility of magnesium insertion/extraction and provide the information on the crystal structure evolution and changes of the oxidation states during cycling.
