Micrometric Growth of V2O5Hexagonal Nano-plates as an Active Material for Lithium Ion Battery Cathode Electrode

This manuscript reports the synthesis of V2O5 nanostructures using reflux method, without using additives such as surface reactants. The influence of reaction parameters like temperature and concentration on the growth of nanostructures have been investigated. It has been observed that the nanostructures are formed with a hexagonal nano-plate morphology, grown from a common core. The diameter of hexagonal nanostructures is around 5 um, and the thickness of nano-plates is less than 250 nm. XRD analysis shows the formation of ammonium vanadates in the reflux step. Calcinating these hydrated ammonium vanadates in 400oC results in formation of microstructures of V2O5. This structures are electrochemically active as the cathode material of Lithium ion battery, with an anodic and a cathodic peak, and can perform reversible reaction.
