Summary:The BET surface area of porous carbonaceous materials obtained by chlorine treatment after devolatilizationof phenolic resin at relatively low temperature 600°C, successive heat treatment and dechlorine treatment, ranged 910to 1080m2/g. When the porous carbonaceous material thus prepared was used as an electric double layer capacitor carbonelectrode, the capacitor exhibited a large electrostatic capacity (about 110mF/m2) The electrostatic capacity of moldedsample was about 30F/cm3 even at a high current density of 500mA/cm2. Therefore chlorine treatment is effective forthe preparation of carbonaceous materials for electric double layer capacitor which is suitable to a high-powersupplementary power source.
