“…The V 2 p 3/2 peaks are further resolved into two contributions, V 4+ and V 5+ . The low valence state V 4+ is known to facilitate Li + ion diffusion and intercalation/de‐intercalation reaction in V 2 O 5 particles . In addition, the XPS O 1s spectra showed that the characteristic peaks ascribed to VO (530 eV) and VOH (531 eV) bonds were found at both the V 2 O 5 samples.…”

Acquisition of high‐energy density is the highest priority requirement and unending challenge in energy storage systems including lithium‐ion batteries (LIBs). One theoretically preferable way to reach this goal is the use of cathode active materials such as vanadium pentoxide (V2O5) that relies on multielectron insertion/extraction reactions. Application of V2O5 to LIB cathodes, however, has been mostly focused on V2O5 materials themselves with little emphasis on V2O5‐incorporated cathode sheets. Here, as an unusual electrode‐architecture approach to achieve ultrahigh‐capacity V2O5 cathode sheets, a new class of self‐standing V2O5 cathode sheets is demonstrated based on V2O5/multiwalled carbon tubes (MWNTs) mixtures spatially besieged by polyacrylonitrile nanofibers (referred to as “VMP cathode sheets”). Notably, the VMP cathode sheet is fabricated directly via one‐pot synthetic route starting from V2O5 precursor (i.e., through concurrent electrospraying/electrospinning followed by calcination), without metallic foil current collectors/carbon powders/polymeric binders. The one‐pot synthesis allows dense packing of V2O5 nanoparticles in close contact with MWNT electronic networks and also formation of well‐developed interstitial void channels (ensuring good electrolyte accessibility). This material/architecture uniqueness of the VMP cathode sheet eventually enables significant improvements in cell performance (particularly, gravimetric/volumetric capacity of cathode sheets) far beyond those accessible with conventional electrode technologies.

“…Doping of transition metal ions is rapidly developing as another testing aspect of improving the electrochemical performance of V 2 O 5 . For instance, doping different amounts of Mn into V 2 O 5 crystal greatly increased the GCD performance, attributed to a more open structure owing to manganese substitution that subsequently favor lithium ions diffusion via vacancy exchange mechanism . Li group reported the both anodic as well as cathodic performance scan be appreciably enhanced by doping V 2 O 5 with SnO 2 (10–15 wt %) that results in a double‐shell based‐nano‐capsules structure .…”

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.

The electrochemical performance of FeVO 4 ·nH 2 O was also studied and it was found that the insertion capacity highly depends upon the water content [16][17][18].…”
