Abstract
The electric double-layer capacitors (EDLCs) are consisted of electrodes, electrolyte and separator. Among of them, electrode materials are generally used carbon materials. In this study, we experimented for the purpose of fabrication of carbon spheres from various carbohydrates as electrode material. Carbon spheres were prepared by hydrothermal synthesis process. Carbon spheres' morphology had been examined using scanning electron microscopy (SEM) and specific surface area had been examined using BET analysis. To confirm the possibilities of carbon spheres as EDLC's electrode materials, we conducted electrochemical tests such as cyclic voltammetry (CV), impedance and cycle ability.
