Here, NiFe2O4, MnFe2O4, and CoFe2O4 nanoferrites are prepared by coprecipitation synthesis technique from nickel, manganese, and cobalt chloride precursors. Synthesized nanoferrites are annealed by calcination process at 800°C for 2 h. To produce a novel anode electrode material for asymmetric supercapacitors (ASCs), the composite material of GO/NiFe2O4‐MnFe2O4‐CoFe2O4 is fabricated. Physicochemical aspects of the synthesized nanoferrites are evaluated. X‐ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and x‐ray photoelectron spectroscopy tests are conducted, respectively. The electrochemical activities are studied by cyclic voltammetry, glavanostatic charge–discharge, and electrochemical impedance spectroscopy (EIS) in 2 M KOH as the electrolyte. In three electrode system, the novel GO/NiFe2O4‐MnFe2O4‐CoFe2O4 electrode displays a high specific capacity of 325 C g−1 and preserves about 99.9% of its initial specific capacity. The GO/NiFe2O4‐MnFe2O4‐CoFe2O4//GO ASCs device is assembled using GO/NiFe2O4‐MnFe2O4‐CoFe2O4, GO, and 2 M KOH solution as the positive electrode, negative electrode, and electrolyte, respectively. Significantly, the GO/NiFe2O4‐MnFe2O4‐CoFe2O4//GO ASCs represent an outstanding energy density of 50.5 W h kg−1 at power density of 2560 W kg−1. Through the long‐term charge discharge cycling tests, this ASC device illustrates about 93.7% capacity retention after 3000 cycles. Then, the present study provides the NiFe2O4‐MnFe2O4‐CoFe2O4 composite nanoferrites as a novel favorable candidate for anode material.Research Highlights
