Graphitic Carbon Nitride for Energy Storage Applications

Abstract

With constant improvement in electrochemical energy storage systems, accumulating energy harnessed from renewable sources has become more effective, affordable, and accessible. Commercialized electrochemical devices such as batteries and supercapacitors have rapidly taken over as energy solutions for medical devices and consumer electronics. To extend the existing electrochemical energy storage infrastructure for permeation into automotive and large-scale applications, as a measure of mitigating carbon emissions, significant steps need to be adopted. The development and inclusion of high-capacity energy storage solutions have been studied using materials based on soil-rich elements as potential electrodes. In this context, the emergence of graphitic carbon nitride (g-C3N4) plays a significant role in improving the energy storage performance of batteries and supercapacitors. The chapter presents an extensive and insightful discussion on the adoption of g-C3N4-based materials and the improvements brought about. This chapter addresses the general merits and demerits of the g-C3N4 for electrochemical energy storage applications. Improvements in the suitability and versatility of the g-C3N4 for commercial usage in Li-ion, Na-ion, metal-air, and Li–S batteries and supercapacitors have been suggested.
