“…Pan et al. successfully prepared V 2 O 5 nanowires with uniform morphology by a simple hydrothermal technique with the addition of disodium citrate as capping agent . They achieved V 2 O 5 nanowires of high crystallinity, high purity and diameter of about 20 nm that exhibited a high specific capacitance of 528.2 F g −1 at 0.5 A g −1 and capacitance retention of ∼85 % after 1000 galvanostatic charging/discharging cycles at 1 A g −1 in 0.5 M K 2 SO 4 aqueous solution.…”

Vanadium pentoxide (V 2 O 5 ) is renowned among the highly efficient supercapacitor electrode-materials for high power and energy densities, excellent specific capacitance, prolonged cycle lives, variable oxidation states of V, reversible nature of interconversions, theoretical importance, etc. Various synthetic methodologies and morphologies, formation of composites, and doping for tuning properties are the additional causes of interest. Different synthetic techniques like sol-gel, solvothermal, electro-deposition, electro-spinning, atomic layer deposition, etc. are employed to prepare V 2 O 5 -based electrode materials with merits and demerits. High rate of material agglomeration and poor conductivity limit its usage in pristine morphology. Accordingly, the impact on charge storage behavior of V 2 O 5 on blending with various carbon-based systems has been explored for materials like activated carbons, conducting polymers, carbon nanotubes and functionalized graphene systems as binary/ternary composites. The aim has been to optimize the key factors such as reduced nanostructure lumping, minimal interfacial resistance and ultrafast charge diffusion across hollow porous structures which may eventually lead to the theoretically expected high specific capacitance (> 1000 F g À 1 ). In this review, we have discussed on the recent progress in the research of V 2 O 5 -based materials and highlighted on the correlation between morphology and electrochemical performances. In the course, we have attempted to delineate the advantage-disadvantages of different composite morphologies that may help to outline the present status and future aspects of these materials that the authors believe will be of first-hand assistance especially to the beginners in the field of research.

“…At high current density, the ions move very fast which reduce the process of intercalation or surface redox reaction thereby decreasing the charge-storage ability. Table 2 shows the specific capacitance values for different current densities with response to various electrolytes [42,43]. Figure 8 displays cyclic stability of V 2 O 5 spindlelike nanostructurein various electrolytes at 10A/g current density.…”

The electrochemical behavior of V 2 O 5 spindle-like nanostructures synthesized through hydrothermal method is studied for supercapacitor applications. The electrochemical supercapacitive performance of the prepared electrode was investigated using cyclic voltammeters (CV), Chronopotentiometry (CP), and Electrochemical impedance spectroscopy (EIS) analyses. The crystallographic structure and phase purity of the V 2 O 5 electrode is investigated by the X-ray diffraction (XRD) analysis. To further confirm the formation of V 2 O 5 , the Fourier-transform infrared (FT-IR) spectroscopy, and Fourier-transform Raman spectroscopy (FT-Raman) investigations were carried out. The formation of V 2 O 5 is confirmed by high-resolution transmission electron microscopy (HR-TEM) analyses. The electrode material delivered a high specific capacitance of 403F/g at 1A/g current density in the mixed electrolyte solution (1 M Na 2-SO 4 ? 0.5 M KOH). In this mixed electrolyte, V 2 O 5 spindle-like electrode showed a good cyclic stability of 3000 cycles with better capacity retention of 85% at 10A/g.
