POLARIZING ELECTRODE AND ITS MANUFACTURING METHOD, AND ELECTRIC DOUBLE-LAYER CAPACITOR

摘要

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.
