“…Two peaks at 1348.3 cm À 1 and 1577 cm À 1 can be observed, which correspond to the D (originating from disordered carbon) band and the G (graphitic carbon) band of carbon, respectively. G band is common to all sp 2 carbon forms and provides information on the in-plane vibration of sp 2 bonded carbon atoms and the D band suggests the disorder and defect structures in carbon [41]. In addition, there are two weak Raman peaks around 1062.4 cm À 1 and 1156.7 cm À 1 , which correspond to the symmetrical stretching vibrations of the PO 4 groups in Li 3 V 2 (PO 4 ) 3 [41].…”

Vanadium-based materials, such as V2O5, LiV3O8, VO2(B) and Li3V2(PO4)3 are compounds that share the characteristic of intercalation chemistry. Their layered or open frameworks allow facile ion movement through the interspaces, making them promising cathodes for LIB applications. To bypass bottlenecks occurring in the electrochemical performances of vanadium-based cathodes that derive from their intrinsic low electrical conductivity and ion diffusion coefficients, nano-engineering strategies have been implemented to "create" newly emerging properties that are unattainable at the bulk solid level. Integrating this concept into vanadiumbased cathodes represents a promising way to circumvent the aforementioned problems as nanostructuring offers potential improvements in electrochemical performances by providing shorter mass transport distances, higher electrode/electrolyte contact interfaces, and better accommodation of strain upon lithium uptake/ release. The significance of nanoscopic architectures has been exemplified in the literature, showing that the idea of developing vanadium-based nanostructures is an exciting prospect to be explored. In this review, we will be casting light on the recent advances in the synthesis of nanostructured vanadium-based cathodes. Furthermore, efficient strategies such as hybridization with foreign matrices and elemental doping are introduced as a possible way to boost their electrochemical performances (e.g., rate capability, cycling stability) to a higher level. Finally, some suggestions relating to the perspectives for the future developments of vanadium-based cathodes are made to provide insight into their commercialization. through the interspaces, making them promising cathodes for LIB applications.
