Development of Tungsten Sulfide Based Compact Paper Electrodes for Supercapacitor Application

Abstract

The increasing need for advanced energy storage devices has prompted research into novel electrode materials for supercapacitors. This work examines the advancement of miniature flexible electrodes composed of tungsten sulphide(WS2), a material recognized for its outstanding electrical conductivity, layered structure, and electrochemical stability. A WS2 composite was created and utilized to construct efficient electrode structures, capitalizing on its flexibility, lightweight characteristics, and economical materials. Thorough electrochemical assessments, including cyclic voltammetry, charge-discharge cycling, and electrochemical impedance spectroscopy, were performed to analyses the performance of these electrodes in terms of capacitance, energy density, power density, and cycle life. The WS2-coated flexible electrodes exhibited exceptional charge storage capacity, rapid ion transit, and improved durability, rendering them appropriate for high-performance supercapacitor applications. This study introduces an innovative method for utilizing WS2 in the creation of economical, versatile, and eco-friendly energy storage systems, suitable for wearable electronics, portable devices, and renewable energy technologies.
