Organic Waste Conversion for the Supercapacitor

The main problems that are now endangering our future are universal solid waste management and its detrimental consequences on the ecology, ecosystem, and worldwide human health index. In this regard, exploring renewable, economical, and ecological material choices for electrode with high adsorption, swift ion/electron transport, and programmable surface chemistry is crucial for developing biocompatible energy-storage systems. The two biggest challenges for supercapacitor are the high price of production and the poor energy density. The current study investigates renewable, economical, and sustainably acceptable electrode materials for future biocompatible energy storage platforms. Organic waste-derived carbon electrode components, such as tree-, fruit-, vegetable-, animal-, and microorganism-based materials, have gained popularity due to their extensive availability, renewable nature, and low cost. Furthermore, the ethical solution to solid organic waste management is to transform trash into useful carbon-based nanomaterials like carbon nanotubes (CNTs), graphene, and carbon quantum dots (CQDs), which can be used as energy storage precursors. This chapter discusses various synthesis approaches for converting and activating organic waste to supercapacitor electrode materials.
