Description
Summary:The development of electrode material for supercapacitors is essential and challenging for the efficient performance of energy storage devices in these decades. Among the various electrode materials, this work focuses on ternary oxides such as copper vanadates, promising candidates for tailorable electrical properties. This study introduces a straightforward method for synthesizing composite phase Copper vanadate nanoparticles (CuV), devoid of templates, and assesses their characteristics through a comprehensive analysis involving FT-IR, Powder XRD, FE-SEM, and XPS techniques. The XRD investigations affirm the presence of multiphase Copper vanadate nanoparticles (CuV). FE-SEM and the EDS spectrum reveal the structure morphologies and uniform distribution of Cu, V, and O elements which are also ensured by XPS analysis. In cyclic voltammetry assessments, the multiphase copper vanadate nanoparticles demonstrate a commendable specific capacitance of 211 F/g at a scan rate of 5 mV/s, maintaining excellent cyclic stability of 94.6% over 1600 cycles, and manifesting a broad spectrum of redox reactions. Furthermore, Electronic Impedance Spectroscopy (EIS) studies unveil an enhanced charge accumulation through a diffusive charge transfer mechanism. These findings suggest that multiphase copper vanadate (CuV) holds promise as an electrode material for supercapacitors.
