description Transition metal selenides (TMSs) are recognized for their excellent electrical and mechanical characteristics, as well as their availability and low cost, which have made them a focal point in materials research. Herein, we explore how multi-walled carbon nanotubes influence the electrochemical characteristics of manganese selenide (MnSe) and molybdenum diselenide (MoSe2) compounds. Specifically, MnSe@MoSe2 electrode was synthesized on MWCNTs using a hydrothermal technique, and after synthesis, the samples were studied by various analytical techniques. Galvanostatic charge-discharge measurements, electrochemical impedance spectroscopy, and cyclic voltammetry demonstrated the synthesized composites’ strong potential for supercapacitor applications. The specific capacitance of MnSe@MoSe2/MWCNT was calculated to be 1033 F/g, maintaining 99 % stability over 2000 cycles at a current density of 5 A/g. Also, the dense morphology of nanosheets showed that the MnSe@MoSe2/MWCNT composite has more electrochemical active sites to absorb more electrolyte ions, facilitating reduced internal resistance, and improved ion transport efficiency. Therefore, these characteristics suggest that the material is a strong candidate for systems with energy storage electrodes.
