Fabrication oF SnS2/Graphene Electrode Using Hydrothermal Method Towards Supercapacitor Applications
Main Article Content
Abstract
Abstract: In the context of climate change and the growing demand for energy, supercapacitors are regarded as one of the key technologies for enabling a sustainable future. In this study, Tin disulfide (SnS2) nanomaterials were synthesized via a hydrothermal method and employed as electrode materials in supercapacitor. The morphology and composition of the synthesized materials were investigated using scanning electron microscopy, energy dispersive X-ray spectroscopy, and X-ray diffraction spectroscopy. The electrochemical performance of both SnS2 and SnS2/Graphene composite electrodes was measured in 2M KOH electrolyte using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS). The SnS2/Graphene electrode exhibited a high specific capacitance of 265.97 F/g at a scan rate of 5 mV/s and 280.5 F/g at a current density of 1 A/g, along with energy and power densities of 19.05 Wh/kg and 354 W/kg, respectively. These findings show that the fabricated electrode is a promising candidate for sustainable energy storage systems.
