Abstract:
1. A method for producing an electrochemical capacitor electrode, comprising the steps of: preparing a coating solution for a polarizable electrode layer that includes porous particles, a fluorine-based binder, a good solvent that dissolves said fluorine-based binder, and a poor solvent that does not dissolve said fluorine-based binder; and coating a collector with said coating solution to form the polarizable electrode layer on the collector, wherein a viscosity of said coating solution for the polarizable electrode layer is set to between 0.5 to 3.5 Pa·s and a weight ratio (GS/PS) of said good solvent (GS) and said poor solvent (PS) is set to between 60/40 to 80/20.
