| Abstract Scope |
In this study, we present Ni2V2O7 (NVO) nanoparticles integrated within a nitrogen-doped reduced graphene oxide (N-rGO) layered structure, serving as a positive electrode material for supercapacitor applications. The composite is synthesized using an inexpensive and easily scalable route of the hydrothermal method. Among the as-synthesized N-rGO-NVO composites, the 40 wt% N-rGO-NVO composite delivers excellent electrochemical performance. It delivered a specific capacitance of 712.5 F g-1 at 1 mA cm-2 current density. An asymmetric supercapacitor (ASC) energy storage device was fabricated utilizing the 40 wt% N-rGO-NVO composite material as the positive electrode while the negative electrode is made from activated carbon (AC). The fabricated ASC device displays an energy density and power density of 14 Wh/kg and 7500 W/kg at 10 mA cm-2 current density. The fabricated ASC device maintains about 75% of its original capacitance retention after undergoing 5000 cycles of charge and discharge at 10 mA cm-2 current density. |
