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 proceeded with experiment for the purpose of fabricating starch-based carbon spheres as more economical alternative measure. Carbon spheres were prepared by two-step process including emulsion method and carbonization. The Carbon spheres' morphology have been examined using scanning electron microscopy (SEM) and we conducted electrochemical tests such as cyclic voltammetry (CV), impedance and charge/discharge to confirm the possibility of this material. |
