Abstract

Vanadium pentoxide (V₂O₅) cathode was fabricated via a facile simple and microwave-assisted method by the utilization of Andrographis paniculata leaf extract as fuel and optimizes the electrochemical applications. The structural and surface morphology of V₂O₅ nanoparticles was analyzed by various spectroscopic techniques like SEM and TEM. The PXRD exhibits an orthorhombic crystal structure with an average crystallite size (32 nm). The band at 497 cm^-1 is attributed to V-O-V stretching vibration through FTIR analysis. The electrochemical characterization of synthesized V₂O₅ nanoparticles was studied towards the lithium-ion battery applications. Various parameters like Charge-Discharge, Cyclic Voltammogram (CV) Columbic efficiency have performed. The V₂O₅ exhibits a reversible capacity of 225mAhg^-1 after 50 cycles. The enhanced performance of the lithium-ion batteries is due to green synthesized V₂O₅ nanoparticles.
