Method of production for active carbon electrode for use as electrical

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.
