Recent Advances in Materials for Supercapacitors

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.

Investigating the properties of co-precipitated nickel cobalt phosphate (NiCoP) nanoparticles for energy storage applications

“…Reversible redox reactions can be ascribed to the peaks seen at the anode and cathode portions. CV test provided insights into the redox behavior [40][41][42], GCD allowed for the assessment of charge storage capabilities [43,44], and EIS offered information on the materials' impedance characteristics [45,46]. These electrochemical analyses give better insight into their electrochemical reactivity and energy storage potential [47,48].…”
