Abstract:
A method of producing a polarizable electrode comprising an activated carbon/carbon composite consisting essentially of an activated carbon component and a carbon component, said activated carbon component comprising activated carbon powder, said carbon component being produced by carbonizing a thermosetting resin, said composite having a density within a range between 0.70 and 0.85 g/cm3, both inclusive, and a thickness within another range between 0.7 and 3.0 cm, both inclusive, said method comprising the steps of (a) mixing said activated carbon powder and said thermosetting resin to produce a powdery mixture, (b) molding said powdery mixture into a molded product having a predetermined shape, and (c) subjecting said molded product to heat treatment in a nonoxidizing atmosphere to carbonize said thermosetting resin so that an activated carbon/carbon composite electrode is obtained as said polarizable electrode, wherein:said molding step is carried out by press-forming under a pressure between 0.1 and 8.0 tonf/cm2, both inclusive.
