The book presents an in-depth review of biomass-derived materials for energy storage technologies. Biomass is the most renewable and abundant carbon resource and has great potential for sustainable energy production. Topics covered include: Bone Char as a Support Material to Build a Microbial Biocapacitor; Biomass Derived Composites; Lignin- and Bamboo Derived Materials, Cellulose-Derived Electrodes; Water Splitting, Fuel cells, and Supercapacitor Technologies. 465 References.
