Abstract

Due to the growing population and modernization of industries, global energy demand will grow by 45 percent by 2030. To deal with a looming energy crisis, there is need for efficient energy storage solutions. The supercapacitor, which has the ability to rapidly charge and discharge, offer a sustainable alternative to traditional batteries. This research is based on the development of supercapacitors with graphene oxide synthesized from organic waste material like rice husk and sawdust. Triiodide is utilized as the electrolyte. By synthesizing graphene oxide from rice husks and sawdust, the method is cost effective and environmentally friendly, benefiting the overall greener energy storage solution. The characteristics of the supercapacitor samples translates into faster charging and higher discharge current relative to battery velocities, meeting a global goal for sustainable energy practices.
