- Abstract
- With the improved microstructure, porosity, and surface area, bimetal oxides make excellent electrode materials for supercapacitor applications. Here, the hydrothermal method for different molar concentration ratios of Nickel and Vanadium sources was successfully used to synthesize the Ni3V2O8 microballs with a porous microstructure. At a current density of 3 mA/cm2, the electrode prepared at a Ni:V molar ratio of 1:0.5 exhibits excellent areal capacitance of 1.56 F/cm2. The Ni3V2O8//AC device is an asymmetrical one, delivering 6.6 mWh/cm2 energy density at 2.2 W/cm2 power densities while exhibiting an area capacitance of 39 mF/cm2 at 8 mA/cm2 current density. With a retention of 72 % for the most recent 5 K GCD cycles, the device exhibits excellent stability for use in practical applications over 5 k GCD cycles at 12 mA/cm2. This research offers a Ni3V2O8 microstructure that offers excellent areal capacitance for energy storage applications. © 2023 Elsevier Ltd
