Effect of Ag Content on the Electrochemical Performance of Ag₂Te Nanostructures Synthesized by Hydrothermal Route for Supercapacitor Applications

Abstract

A massive amount of power is required to meet the worldwide need for gratifying human aspirations. As a result, the possible effect on the energy storage equipment is crucial to ensure a steady supply of energy. However, a supercapacitor is a potential device that provides a sustainable source of energy. In the current work, we presented a fabrication of Ag 2 Te at different concentrations of 0.006, 0.012, 0.025, 0.05, and 0.1 M via a hydrothermal approach for energy storage devices. A variety of analytical techniques were employed to assess its structure, morphology, and textural property regarding the fabricated electrode. Among different electrode materials, the Ag 0.025 Te electrode exhibited the large C s of 711.86 F g −1 , E d of 35.12 W h Kg −1 , and P d of 298.4 W Kg −1 at a current density of 1 A g −1 . The stability test of Ag 0.025 Te shows 92.96% retention of capacitance over 5000 GCD cycles with little destruction in the structure as determined by XRD. EIS responses indicated that the improved performance in 1.0 M KOH is because of low hydration sphere radius, strong ionic conductivity of K + , and less electrode resistance. The encouraging results suggest that the Ag 0.025 Te nanorod might provide an ideal cathode material for supercapacitor applications.
