In addition, vanadium oxide (V2O5) has been exploited as a catalyst in several industries such as sulfuric acid production (Romanovskaia et al., 2021), CO2 methanation (Świrk et al., 2021), formaldehyde production (Laitinen et al., 2020) and the ceramic industry (Fan et al., 2021). Vanadium also has several applications in the optical domain. It is used as glass colorant to produce green or blue tint. Glass coating with vanadium dioxide (VO2) can help in blocking infrared radiation at specific temperature (Monakhov et al., 2004). There are also several applications of V in pharmaceutical industries. Due to the similarity between vanadate and phosphate, V-based therapeutics have been exploited in several signaling pathways (Pessoa et al., 2015). Vanadium-based therapeutics are documented for their antidiabetic effects on both glucose and lipid metabolism (Jakusch & Kiss, 2017; Patel et al., 2019). Recently, anticancer properties of V-based therapeutics have been investigated, given their promising antitumor effects (Nunes et al., 2021). Interestingly, V compounds have been introduced as potential therapeutic agents for COVID-19 (Semiz, 2022).

The greatest hazards of mining vanadium are exposures to uranium and radon in the case of carnotite ores, and to the silica in the rocks of the mines. Much of the extraction of vanadium is a wet process, minimizing the respiratory exposure risks. Vanadium oxide can produce a respiratory sensitization with inflammation, irritation, and sometimes pneumonia. Sensitization of the skin produces redness, itching, and eruptions.
Application of Nanomaterials for Lithium Ion Batteries

Vanadium oxide (V2O5) is a typical intercalation compound as a result of its layered structure. For Li-ion intercalation applications, vanadium oxide offers the essential advantages such as low cost, abundant source, easy synthesis, and high energy densities. Tuning the morphology or texture of V2O5 to obtain high-surface-area composite electrodes which can compensate the slow electrochemical kinetics and slow diffusion has been investigated (Le et al. 1996). V2O5 aerogels, which are mesoporous materials where the nanometer-sized domains are networked through a continuous, highly porous volume of free space, were reported to have electroactive capacities up to 100% greater than polycrystalline non-porous V2O5 powders (Dong et al. 2000). In another example, V2O5 nanoroll was prepared by a combination of sol-gel method and hydrothermal treatment (Krumeich 1999). The nanoroll V2O5 possesses four different sites, that is, tube opening, outer surface, inner surface and interstitial sites, compared to other tubular system and it showed better electrochemical performance. Also, defects in V2O5 nanoroll influence its electrochemical performance. It was reported that the specific capacity of defect-rich nanorolls was higher than that of well-ordered nanorolls (Muhr et al. 2000).

The family of vanadium oxide materials has attracted a huge attention in the research community recently due to their interesting ionic, electronic and physical characteristics. These compounds have many potential applications. These compounds can be used as cathode which is used in battery. These compounds are also suitable for electrochromic devices [1–5]. In the family of vanadium oxide, the Co-based vanadium oxide compounds are the subject of great interest in condensed matter physics and material science due to their many attractive characteristics including strong anisotropic character [6–9], magnetic field induced transition [6,10], quantum criticality nature [11–13], etc. Due to these remarkable characteristics not only Cobalt based but also Ni, Mg, Zn, Fe, W and Te-based vanadium oxides are synthesised and characterised in different time. Though a considerable amount of progress has been done to study the different physical and chemical nature of these compounds, however there is still lack of knowledge about the complete behaviour of these oxides. The general structure of vanadium oxide family is AV2O6 (where, A = Co, Mg, Ni, Zn, Fe, W and Te). It possesses the FeTa2O6 type (mineral tapiolite) crystal structure. In 1997 N. Kumada et al. first reported the trirutile type bismuth oxide [14].
