Abstract Nanostructured electrodes with large surface area are essential for studying charge storage mechanisms in supercapacitors. Biomass-based carbonaceous porous electrodes have proven to be good candidates for supercapacitor application. In this study, micropore and mesopore dominated carbon materials derived from Agave sisalana sisal waste were prepared through carbonization and chemical activation with ZnCl2.
