Over the years, one of the major global problems has been the rapid increase in food waste. Food that could potentially feed many people is not only wasted but also contributes to global warming. One possible solution to this problem is supercapacitors, as they offer a cheap and reliable energy storage option. Most supercapacitors today use carbon electrodes, and there has been growing interest in utilizing various organic materials as carbon sources. In this study, the researchers designed and constructed composite electrodes derived from jackfruit rinds combined with titanium dioxide (TiO2) for supercapacitors, which were then measured for their electrical properties. About 0.5 grams of an activated carbon composite material produced from jackfruit and TiO2 were used to fabricate each supercapacitor sample. The carbon composite mixture was then spread onto two 0.05 mm-thick aluminum sheets. These supercapacitors have a specific capacitance ranging from 119.26 to 177.04 Farads per gram and operate at a rated voltage of 2.7 V. This range of specific capacitance aligns with data from other studies focused on supercapacitors incorporating similar materials. This consistency demonstrates the reliability and effectiveness of the composite material used, supporting its potential for broader applications in energy storage technologies.
