Abstract
It is the objective of the present invention to provide an active carbon electrode which is of sufficient mechanical strength to be formed into a large plate, may be suitably used as an electrical double layer condenser capable of a large current discharge, and which can realize a high capacitance. The method of production for such an active carbon electrode comprises the steps of a) producing a carbon base material by carrying out a first activation treatment to a carbon material obtained by carbonization of a carbon compound; b) producing a formed body by adding a binder to the carbon base material; c) carbonizing the formed body; and d) producing an active carbon electrode by carrying out a second activation treatment to the carbonized formed body.
