Designing highly efficient ternary composite electrode materials with novel nanostructures plays a crucial role inenlightening both the high energy density and structure stability of supercapacitors. In this connection, wesynthesized MXenes (Ti₃C₂) adorned tungsten disulfide (WS₂) and nickel cobalt phosphate (NCP) using a probesonication process and facile hydrothermal method, respectively. The integration of WS₂ quantum dots and NCPmicroflowers within the Ti₃C₂ layers (NCP-M-W) significantly enhances the electrocatalytic efficiency of the NCPM-W composite by eliminating the restacking issue, thereby making it a highly effective electrode for energystorage applications. Subsequently, the advantages of synthesizing the NCP-M-W with ternary metal formulationincrease the layer-to-layer distance that allows the KOH electrolyte to penetrate the inner surface of the electrode. Due to the optimized inter-layer spacing, the NCP-M-W electrode achieved an impressive specificcapacitance of 1020 F/g at a current density of 1 A/g. Interestingly, the fabricated NCP-M-W//AC asymmetricsupercapacitor device (ASC) delivered outstanding energy and power densities of 38 Wh/kg and 703 W/kg at the1 A/g current density owing to high specific surface area with more metal active sites and good conductivity.Whereas, the capacitance retention and coloumbic efficiency of the fabricated device are 73 % and 99.5 % for15,000 cycles respectively. Hence, these results distinctly reveal that the prepared ternary electrode NCP-M-Wcan act as a proficient and reliable option as an electrode for high-performance supercapacitor applications.
