Title:
POLARIZING ELECTRODE AND ITS MANUFACTURING METHOD, AND ELECTRIC DOUBLE−LAYER CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2003/028053
Kind Code:
A1
Abstract:
An electric double−layer capacitor comprises a carbon composite electrode serving as a polarizing electrode (31) and made of a single−layer carbon nanohorn aggregate having a specific structure and a very large surface area. The single carbon nanohorn aggregate is mixed with a phenol resin, the mixture is formed and heated to produce a carbon composite electrode. The carbon composite electrode is impregnated with an electrolyte to become a polarizing electrode. An electric double−layer capacitor comprising this polarizing electrode has a large capacitance and is capable of discharging with large current.
