Supercapacitor electrodes based on biowaste

This study presents a compelling overview of biowaste as a valuable, carbon-rich material for electrode components in supercapacitors. Easily sourced from local environments, biowaste offers numerous advantages that make it an appealing choice for sustainable energy solutions. We have carefully compiled a list of biowaste materials that can be converted into high-performance electrode materials, providing detailed information on specific capacitances, power and energy densities, voltage windows, and cycling stability. The innovative extraction of activated carbon from biowaste represents a challenging yet highly promising approach for creating carbon-based electrodes. Carbon contributes significantly to enhancing the efficiency and performance of energy storage devices. With a diverse array of biowaste materials readily available, substantial efforts are being made to transform these resources into valuable carbon-based materials through various synthesis techniques discussed in this study. Our research rigorously assesses the effectiveness of activated carbon derived from different waste sources, demonstrating its potential as a supercapacitor with impressive specific capacitance and power density metrics. Adopting biowaste solutions can help shape a cleaner and more efficient energy future.
