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.
