Estimating the term…
A carbonaceous material having a total pore volume of from 0.5 to 1.5 cm3/g per unit mass, a volume of micropores having diameters of from 10 to 20 Å of from 10 to 45% based on the total pore volume, a volume of mesopores having diameters of from 20 to 200 Å of from 35 to 65% based on the total pore volume, a volume of macropores having diameters exceeding 200 Å of not more than 15% based on the total pore volume, and a specific surface area of from 1,000 to 2,500 m2/g. The carbonaceous material is incorporated into an electric double layer capacitor to provide increased capacitance.
