Title:
SOLID ACTIVATED CARBON STRUCTURE, ELECTRIC DOUBLE LAYER CAPACITOR USING THE SAME AND THEIR PRODUCTION
Document Type and Number:
Japanese Patent JP3872222
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electric double layer capacitor having a high electrostatic capacity and high reliability, in which a solid activated carbon structure having high specific surface area, high mechanical strengths and excellent durability to vibration or the like is used as a polarizing electrode.
SOLUTION: This solid activated carbon structure 2 comprising a laminated body composed of a first solid activated carbon layer containing, as a main component, activated carbon having a specific surface area of 1,500-13,000 m2/g, being measured by a nitrogen adsorption method (BET method) and a second solid activated carbon layer containing, as a main component, activated carbon having a specific surface area of 500-1,400 m2/g is used as the electrode of the electric double layer capacitor 1.
