Chapter 2 - Exploring smart graphitic carbon nitride material toward flexible energy storage supercapacitors

Abstract

Rapid proliferation of research in the field of energy storage has been driven by tremendous progress in nanostructured materials. Fabrication of flexible energy storage electrodes has gained much attention due to rapid growth of portable and wearable devices. Carbon-based materials like graphitic carbon nitride (g-C3N4) have been explored significantly due to their superior physicochemical as well as electrochemical properties. Presence of nitrogen along with strong π bonds significantly enhances the electrochemical activity and stability, by promoting electron donor-acceptor properties. In this aspect, this chapter deals with progress of nanostructure g-C3N4 material in domain of flexible supercapacitors (FSC). FSC developed using g-C3N4 materials are efficient, lighter, and portable. While engineering the brilliant system, apart from its surfaces, energy storage also occurs within the interface by fast ion-exchange kinetics. These miniature devices due to their versatile functionalities as energy storage systems are receiving great importance in the modern era. Thus advanced energy storage g-C3N4 systems with efficient outcomes are essentially required to be engineered.
