EDLCs are consisted of cathode, anode, electrolyte and separator. Among of them, the electrolyte is regarded most prospect possibility. Especially PC-based electrolyte was already known to have pretty good properties. But there are some disabilities. By mixing electrolyte, we can solve those problems; internal resistance, ion conductivity, electrochemical reversibility and so on. Internal resistance should be minimized to prevent potential reduction at high current density. In this study, to confirm moderate composition of electrolyte mixing ratio, we mixed some organic electrolyte. Internal resistance was measured by impedance. Also, reversibility of electrochemical reaction was measured by CV. |
