Chemically activated carbons derived from cashew nut shells as potential electrode materials for electrochemical supercapacitors

Carbon Resources Conversion, Journal Year: 2024, Volume and Issue: unknown, P. 100267 - 100267

Published: June 1, 2024

Supercapacitors are widely recognized as energy storage solutions due to their high power densities and long cycle lives. Furthermore, there is growing scientific technological interest in converting biomass waste into carbon materials for manufacturing supercapacitor electrodes. In addition abundance cost-effectiveness, the appeal of carbons derived from lies tunable porosity, which enables rational design achieve desired performance supercapacitors. Here, we present synthesis activated cashew nut shells via potassium hydroxide (KOH) activation at different temperatures (650, 750, 850 °C). The resulting exhibited amorphous predominant microporous structures.
