            Abstract

            The fluctuating availability of energy sources has encouraged the development of energy storage devices such as supercapacitors. Supercapacitors are good electrochemical energy storage materials that have demonstrated promising efficiencies in diverse applications. They are able to release high power at low energy operating conditions. In this article, we introduce basic knowledge on supercapacitors, their different classifications, and their relevance to material development. We outline the progress made on diverse materials adopted in improving the performance, charge retention, and stability of supercapacitive materials. Finally, we discuss the different methods utilised in obtaining highly stable supercapacitors.
