Abstract

The next-generation supercapacitor (SC) ought to be deliver excellent high energy density (ED), power density (PD) with outstanding cycling stability using sustainable doping materials. Heteroatoms like N, S, B, and P doped and co-doped with carbon materials are examples of sustainable functional materials for next-generation SCs. In the case of SCs, heteroatom doping with carbon has produced interesting effects, which we will discuss in this chapter. Although there is a wealth of literature on N-doped composites study for energy storage applications, there has been a scarcity of reviews on other doped composites. As a result, the objective of this chapter is to present critical insights and an up-to-date outline of current advancements, future research prospects, and the processes used to synthesize these doped functional materials. Following that, the benefits and drawbacks of using sustainable heteroatom-doped carbon materials will be discussed. The electrochemical (EC) performance of mono or multi-doped carbon composites as electrodes in EC capacitors is critically evaluated.
