The less emission, environmental friendliness and hazardous energy storage materials are most impotent to the clean system. Here we synthesis rGO anchored nickel vanadate nanorods for supercapacitor application. As a result, Ni2V2O7 rGO@Ni2V2O7 nanomaterials show monoclinic structure from XRD pattern. vibrational of V–O–V Ni–O along with main peak carbon indicates anchoring in FTIR Raman spectra. SEM TEM images illustrate rod shaped was attached over sheet surface. From BET analysis, sample has higher surface area than electrode. Further, application electrodes shows 318 F/g 624 at 1 A/g capacitance values. Although, electrode power (771 W/kg) density (22.28 Wh/kg) values NiV2O7 Moreover, exhibits 95% retention value even 1000th cycle. prepared Rct 4.72 Ω) (9.86 Ω). attachment can provide area, conductivity lower resistivity According these results, is more suitable electrodes.
