Abstract (en)

[origin: CA2797917A1] An activated, porous carbon has a specific BET surface area of between 1400 and 1900 m2/g, with at least 80% of all of the pores, and preferably all of the pores, of the carbon having an average diameter of between 0.3 and 0.9 nm. A carbon of this kind is suitable especially for use as an electrode in a double-layer capacitor, and is obtainable by a method which comprises the following steps: a) producing a mixture of a green coke, a base, and a hydrophilic polymer which is chemically inert towards the base, b) pressing the mixture produced in step a), to form a compact, and c) activating the compact produced in step b).
