Abstract:
Due to rapid technological development, the energy demand is pushing humanity to the limits in the exploration of high-performance energy devices. In the realm of energy storage devices, supercapacitors are considered the most promising option. Supercapacitors have become the most popular and significant energy conversion storage system in the case of current renewable and sustainable nanotechnology. Supercapacitors are one of the advanced breakthroughs in every application because of their large energy capacity and ability to supply with relatively short periods and longer lifetimes. Supercapacitors possess paramount importance because of their appreciable features. It serves as an alternative energy storage solution due to its significantly higher power density and cyclability compared to batteries, which enhances its flexibility while compromising energy storage. Low energy density of supercapacitors limits their practical applicability; thus, significant efforts have been undertaken to improve their energy density. Carbon quantum dots have recently been generally used as electrode materials to improve the energy density of supercapacitors by functioning as an electrode material additive or derivative material. This review focuses on the application of carbon quantum dots in supercapacitors.
