Document Type and Number:
Japanese Patent JP4733707
Kind Code:
B2
Abstract:
An object of the present invention is to provide an electric double layer capacitor carbon material and an electric double layer capacitor which can exhibit excellent charge/discharge characteristics. The carbon material for electric double layer capacitors in accordance with the present invention is characterized in having the BET specific surface area in a range of 300 - 1000 m 2 /g, the carbon interlayer distance in a range of 0.360 - 0.380 nm and the carbon strength of 2000 cps or more. This enables to form an electric double layer capacitor having a high capacitance and a low internal resistance. The electric double layer capacitor of the present invention utilizes this carbon material as a polarizable active material. The capacitor of the present invention exhibits a high capacitance and a low internal resistance.
