Upcycling of Solid Waste into Quantum Dots for Supercapacitors

This chapter examines the innovative conversion of solid waste into zero-dimensional quantum dots (QDs) for supercapacitor applications. It emphasizes the “trash to treasure” concept, demonstrating how this process yields both economic benefits and environmental sustainability. Furthermore, it highlights the performance enhancements these materials provide. This chapter categorizes various types of QDs derived from waste sources, each exhibiting unique characteristics that improve energy storage capabilities. The discussion outlines the advantages of integrating these upcycled materials into supercapacitors, including enhanced charge storage capacity and energy density. Through successful case studies and an exploration of the challenges involved in incorporating upcycled QDs into energy storage systems, this chapter showcases the potential for transforming solid waste into valuable resources for advanced supercapacitor technologies, ultimately fostering more sustainable and efficient energy solutions.
