[Characteristic] It uses the phenomenon (electrical double layer) that aligns the ion and charge carrier in the interface of the solid-state electrode and the electrolytic solution, and uses the interval between the ion and the charge carrier as a dielectric. Its characteristic is ultra high capacity and can be used as backup power supply for the memory of electronic equipment and watch circuit. [Type of capacitor]
