Title:
ELECTRIC DOUBLE-LAYER CAPACITOR USING ACTIVATED CARBON FIBER AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2005294607
Kind Code:
A
Abstract:

To provide an electric double-layer capacitor of high capacity that can suppress electrode expansion during usage and has decay resistance against repetitive charging and discharging and its manufacturing method.

An electric double-layer capacitor using an activated carbon fiber as an electrode material employs an electrode material manufactured by forming fibers of mixture mainly composed of at least one kind of fiber formation high polymer for making an anti-graphitized carbon by heating the activated carbon fiber, and at least one kind of fiber formation high polymer for making a pro-graphitized carbon by heating same carbon fiber melted in the common solvent like water or organic solvent, extending and hardening the formed fibers and then carbon-activating the resulting composite fibers.
