An electrode material for an electric double layer capacitor containing a carbonaceous material and a carbonaceous material, an electrode for an electric double layer capacitor, and an electric double layer capacitor

摘要

An object of the present invention is to provide a carbonaceous material having a high capacitance and further capable of maintaining a high capacitance and an energy density over a long period of time, and a production method thereof. And a specific surface area by the BET method 1,200 ㎡ / g ~ 1,800 ㎡ / g, an R value is 1.2 or more due to the Raman spectrum, G-band half-width is a carbonaceous material having 70 ㎝ ^-1.
