ABSTRACT
This chapter covers the recent advancements for the effective utilization of biomass for the fabrication of carbon nanostructures based electrode materials for energy storage applications in supercapacitors. Biomass is available in large quantity and produced from waste generated from various sources such as agriculture residue, tree leafs, food waste, nutshells, household and industrial activities. They contains celluloses, hemi-celluloses and lignin 262biopolymers, which can be considered as carbon source and one can get the activated carbon of industrial importance. The basic principles of energy storage devices e.g. supercapacitors, synthesis, characterization and performances of various electrode materials are discussed. The potential of carbon nano particles for energy storage applications has not been fully recognized yet. However, the trends for future developments are very promising.
