[Display omitted] •Ni3V2O8 were successfully prepared by simple hydrothermal method.•Ni3V2O8 NPs modified electrodes exhibits high Csp of 581C/g.•The constructed Ni3V2O8||AC device exhibits PD of 1976 W kg & ED of 45.5 Wh/kg. A key challenge in renewable energy production is the persistent gap between energy supply and demand. Developing and optimizing materials for energy storage devices offers a promising solution to this issue. The Ni3V2O8 Nanoparticles (NPs) were prepared using a simple hydrothermal process and their structural, morphology, functional and elemental properties were confirmed with special analytical tools like PXRD, SEM, FTIR and EDX with mapping correspondingly. Ensuring the redox peaks and electrochemical interaction, charge/discharge cycles and conductivity of electrode materials were examined through the CV, GCD and EIS studies. The prepared Ni3V2O8 electrode exhibits a superior specific capacity of 581.07 at 5 mV/s. The cyclic stability of the electrode attained 72 % specific-capacity retention completing 10,000 cycles with 5 A/g. The supercapatteries belong to the electrode configuration of Ni3V2O8||AC fabricated and also investigated its properties with capacitive and diffusive mechanisms. Additionally essentially, fabricated asymmetric supercapatteries with a notable power density (PD) and energy density (ED) 1976 W/kg and 45.5 Wh/kg and outstanding cycle stability performance above 92 % specific capacity retention after 10,000 cycles is accrued effectively by using the Ni3V2O8 as electrode material for supercapattery applications.
