Designing highly efficient, low-cost hybrid nanostructures with having favorable morphology and excellent conductivity is very promising for electrodes used in electrochemical storage devices. This study shows the synthesis of a new three-dimensional (3D) hybrid structure consisting of lanthanum nickel oxide (LaNiO₃) perovskite, graphite carbon nitride (g-C₃N₄), and reduced graphene oxide hydrogel (RGOH) structures for the new hybrid supercapacitor (SC) application. The 3D hybrid structure, which is a new SC application, draws attention according to the specific capacitance (C_s) result for graphene-based hydrogel structure. For this purpose, while g-C₃N₄ is selected to plays an important role to increase the electrochemical activity of SC, the LaNiO₃ perovskite structure is used to increase the discharge capacity of SC as well as to provide high discharge current and long cycle life. As a result of electrochemical studies, the superior capacitive performance of LaFeO₃/g-C₃N₄@RGOH showed C_s and unique performance of 750.56 F g⁻¹ at a current density of 1 A g^–1. The 3D structure is used as anode material for fabricating symmetric two-electrode supercapacitor systems. Moreover, the LaFeO₃/g-C₃N₄@RGOH materials display magnificent cyclic stability of 82% for 5000 cycles at a current density of 10 A g ^{− 1}, which claims the new material progress in the energy field.
