Electric Double Layer Capacitor (EDLC) is one of the electrical storage devices. Compared with secondary batteries, EDLC is able to charge and discharge quickly, has long life-time and is eco-friendly. However, energy density is inherently low due to surface limited reaction. Then increase of the surface area is required for the practical application. Carbon nanotube (CNT) has large specific surface area. In this study, CNT is utilized to fabricate electrodes with high surface area.
