Recent Development in Flexible Supercapacitors

Abstract

Energy has remained one of the top priorities of researchers for its maximum conservation due to the rapidly depleting conventional energy resources. The recent developments in the field of energy storage have compelled researchers to explore the power and potential of supercapacitors. These efforts have revealed the hidden yet unique benefits of supercapacitors for producing highly advanced and smart flexible wearable devices and consumer electronics. The ongoing researches have explored the performance, potential, and capacity of supercapacitors in comparison with conventional capacitors. In this chapter, different types of materials and methods utilized to facilitate energy storage have been discussed. In particular, the use of graphene with metal oxides, chalcogenides, and conductive polymer materials along with mechanisms have also been emphasized in detail. Additionally, the recent advancements on various supercapacitors and their possible applications, including sensors, smart, flexible devices, consumer electronics, hybrid vehicles, advanced energy storage systems, heavy machinery, power grid systems, etc. were considered as the heart of this chapter. Further, the prospects of supercapacitor-based devices which hold promising innovations in advanced energy storage processes are also systematically highlighted.
