Abstract
Recently, Quantum dot nanomaterials have been explored to a great extent
for their exciting properties. Their application as electrodes to produce clean energy
and hazardous chemical-free components of supercapacitors is the most interesting.
The quantum dot electrodes are found to offer high charge storage capacity as well as
stability that ultimately boosts their demand in advanced hybrid supercapacitors. This
chapter discusses the synthesis, physiochemical features, properties, and electrochemical performance of various quantum dots. Additionally, insights into their
electrochemical properties in different supercapacitors are illustrated. The best
operational parameters are highlighted to provide readers with the future scope of this
research area.
