Material Karbon Berbasis Biomassa Akar Ilalang Dengan Pengaktifan Kimia Ganda…

ABSTRACT Supercapacitors are energy storage devices that have high power density and high energy density. One of the main components in a supercapacitor cell is the electrode. In this study, carbon electrodes were made from weed root biomass by optimizing multiple chemical activations with various concentration variations to obtain high specific capacitance. The grass root biomass was synthesi…
