Abstract
Supercapacitors have received a lot of interest in recent years due to their better power density and longer cycle life than secondary batteries, as well as their higher energy density when compared to normal electrical double-layer-capacitors. Unlike other forms of capacitors, the most essential feature of supercapacitors is their ”super” high energy density. The electrochemical device has demonstrated excellent performance by refining electrode materials, exploring alternative electrolyte solutions, incorporating them into new cell designs, and so boosting their performance to satisfy the needs of high energy and power requirements. Activated carbon, transition metal oxides, and conducting polymers are among the materials that might be used as supercapacitor electrode materials. Supercapacitor development is ongoing across the world, with significant progress being made in increasing their electrochemical performance. However, markets for supercapacitors have yet to emerge, owing mostly to their high cost and limited energy density. There are two major elements that may influence the pricing. One option is to use lower-cost electrode materials, such as nanofibers and low-cost metal oxides, resulting in cheaper material costs. The main objective of this research is to create new electrode materials for supercapacitors that have increased energy density while maintaining high power density and a long cycle life.
