AGRICULTURAL WASTE AS A PANACEA FOR HIGH COST OF ELECTROCHEMICAL DOUBLE LAYER SUPER-CAPACITOR AND SUSTAINABLE ENERGY STORAGE SOLUTION: A REVIEW

Abstract

Supercapacitors, also known as ultracapacitors or electrochemical capacitors, are energy storage devices that store and release energy quickly. They are used in various applications, including renewable energy systems, electric vehicles, and electronics. Using agricultural waste as a source for supercapacitor’s electrode materials is an innovative and sustainable approach that holds promise for addressing the high cost of these materials. Agricultural wastes, such as crop residues, husks, shells, and other byproducts, often presents challenges in terms of disposal and environmental impact but have proven to be a good precursor material for the synthesis of electrochemical super capacitor’s electrode. By repurpose these waste materials for supercapacitor electrodes, the high cost of the electrode will be reduced and hence the overall cost of the supercapacitors.
