Abstract :

High specific surface area and electrical conductivity of nanostructure metallic sulfides is very fundamental to attain high specific capacitance, energy density and power density of an electrode material for supercapacitor applications. Graphene oxide (GO) based strontium sulfide nanorods like morphology have been fabricated by employing hydrothermal method. The determined high electrical conductivity, surface area, as well as the mechanical support offered by GO makes the strontium sulfide nanorods electrochemically active electrode structure. The CV curves with well-defined redox peaks confirm the pseudocapacitive behavior of GO based strontium sulfide nanorods in 2 M KOH electrolyte. The specific capacitance and energy density has been extracted from the GCD profile as 1831.14 Fg-1 and 91.56 WhKg-1 at the current density of 3 mA cm-2. The electrochemical impedance also confirms the pseudocapacitive nature of strontium sulfide nanorods electrode materials. The two electrode symmetric behavior of strontium sulfide nanorods also showed excellent electrochemical behavior. Hence, the experimental results suggest that strontium sulfide nanorods is a very suitable electrode material for supercapacitor applications.
