One of the most promising bimetallic sulphides for use in energy-storage systems is NiCo2S4, but further research required to give it a high reversibility and electrochemical reaction capacity. In this study, we show rational materials design an ideal NiCo2S4 nanoparticle as NiCo2S4/RGO nanocomposite, embedded reduced graphene oxide (RGO) matrix. nanoparticles, which ranged size from 20 25 nm were firmly fixed on surface RGO sheets, made up produced composite. As predicted, nanocomposite displayed specific area, mesoporous structure, conductivity, resulting large electroactive area rapid electron ion motion. Additionally, present advancements material science, showcasing electrode, has long cycle life 5000 cycles, capacitance retention 85.6 %, exceptional 1505 Fg-1 at 1 Ag-1. A active-material loading asymmetric supercapacitor serves example real-world use. The exhibits 48 Whkg-1 energy density power 985 Whkg-1, while maintaining 7227 Wkg-1 Whkg-1. stability efficiency validate that our methodical science technology optimisation areas active substance synthesis, electrode expansion, device design/fabrication will help advance development high-performance supercapacitors future years.
