ELECTRIC DOUBLE LAYER CAPACITOR MATERIAL USING CARBON NANOTUBE

摘要

PROBLEM TO BE SOLVED: To provide a new material that can be used as an electrode for an electric double layer capacitor making use of characteristics of a carbon nanotube. SOLUTION: The material for the electric double layer capacitor comprises a gel composition comprising: subdivided carbon nanotube which has been obtained with the application of shear force under the presence of ionic liquid; and the ionic liquid. The material can be utilized for an electric double layer capacitor which has a large electric capacity per surface area and a simple configuration as a device, and makes use of the characteristics of the ionic liquid.
