Biomass-Derived Carbons and Their Energy Applications

Abstract

In this chapter, a few interesting findings on renewable carbons derived from various biomass precursors and their electrochemical applications, especially supercapacitors and lithium-ion batteries were discussed. Electrochemical energy storage devices are progressively crucial since it helps in a significant reduction in the use of different fossils-based resources. The use of energy storage devices in a particular system rests on the nature of the electrode materials. Among an extensive range of electrodes, biomass-based carbons have gained significant consideration as an electrode because of their variable physicochemical features, environmental concern, and commercial value. We have also discussed a few recent developments of biomass-derived carbons and some important techniques such as carbonization and activation conditions that control their property and performance of carbon electrodes. Besides, some of the parameters such as pore structure, surface property, and degree of graphitization, which regulate the electrochemical functioning of the device were discussed in detail. In the final section of this chapter, we included some energy storage applications of biomass-based carbons, and their effectiveness as an electrode were summarized. In brief, this chapter provides a fundamental understanding of several biomass-derived carbon materials and suggests the essential strategies for the fabrication of various energy storage systems.
