Electrochemical engineering of MoS2-Grown NiCoP hybrid electrodes on nickel foam for enhanced supercapacitor performance

In the present work, molybdenum disulfide (MoS₂) was synthesized on nickel cobalt phosphide (NiCoP)-coated nickel foam (NF) using cyclic voltammetry (CV) as an effective electrode material in supercapacitor. The physical, chemical, and electrochemical properties of the electrodes were evaluated using different characterization techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET), cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and galvanostatic charge/discharge (GCD). The electrochemical performance of this bilayer-structured electrode was investigated. The two-layered structure of NiCoP@MoS₂ provided a high specific capacitance of 2352.407 F g^-1 at 1 A g^-1, energy density of 52 Wh Kg^-1 at power density of 321 W Kg^-1. Consequently, the NiCoP@MoS₂ electrode material is expected to be a promising option for supercapacitor applications and other energy devices.
