ELECTRIC DOUBLE LAYER CAPACITOR AND ELECTRODE MATERIAL THEREFOR

Title:

ELECTRIC DOUBLE LAYER CAPACITOR AND ELECTRODE MATERIAL THEREFOR

Document Type and Number:

Japanese Patent JP2005252116

Kind Code:

A

Abstract:

To obtain a higher capacity by improving a carbon nanotube used for an electrode material in an electric double layer capacitor using the carbon nanotube for the electrode material.

In the electric double layer capacitor constituted by storing a pair of electrodes 1, 2 and an electrolytic solution in a capacitor can, an electrode material for the electric double layer capacitor is used in which a defect is formed on the wall surface of a carbon nanotube, and the ratio (ID/IG) of peak strength ID around 1,350 cm-1 to peak strength IG around 1,580 cm-1 which is measured by a Raman spectrum analysis method is ≥1.6.
