    • Abstract

       

      Vanadium oxide-based nanomaterials have been showing great promise as cathode materials for lithium-ion batteries (LIBs). Among these, nanostructured V2O5 shows a high discharge capacity due to its layer structure and thermodynamically stable form. This work reports the synthesis of V$_2$O$_5$ nanoparticles via a simple low temperature hydrothermal method using ammonium vanadate and quinol. The reduced size of V$_2$O$_5$ has resulted in the blue shift of the absorption spectrum. The material has been examined as a cathode material to study lithium intercalation/deintercalation. It shows aninitial discharge capacity of 310 mAh g$^{−1}$ at a current density of 0.1 mA g$^{−1}$ at 1.5–4 V and retains a specific discharge capacity of 184 mAh g$^{−1}$ even after 58 cycles. The present study manifests how the nanostructured size V$_2$O$_5$ could be applied as a high-energy cathode material for LIBs.
