PURPOSE:To maintain high electromotive force and charge current density and make it possible to control osmosis of electrolyte by controlling mainly the grain size of a raw material resin and active carbon. CONSTITUTION:In a nonburnt electrode, wherein a resin is mixed with active carbon while being heated and solidified, active carbon having the grain diameter of not more than 200 meshes and two kinds of resin having the grain diameters of not more than 100 meshes and not more than 300 meshes respectively are used as raw materials and said three kinds of raw materials are mixed to be followed by heating and deposition thus to form a state, wherein resins of two kinds, namely, large and small grain diameters are mixedly existing and deposited in an active carbon layer, thus to be molded. The critical range is difficult to be found for the compounding ratio of said three kinds of raw materials. It is, however, recommended that the range may preferably be active carbon 75-80wt%, the resin having the grain diameter of not more than 300 meshes 13-17wt% and the resin having the grain diameter of not more than 100 meshes 3-12wt%. |
