Abstract
A method is provided for optimizing the physical characteristics of a coating solution for an undercoat layer formed between a polarizable electrode layer and surface-roughened collector. A first step is carried out to form an undercoat layer on a collector whose surface has been roughened, and a second step is carried out to form a polarizable electrode layer on the undercoat layer. The first step is performed by coating the collector with a coating solution for the undercoat layer that includes electroconductive particles, a binder, and a solvent; the viscosity of the coating solution for the undercoat layer is set to from 0.15 to 0.75 Pa·s, and the weight ratio (P/B) of the electroconductive particles (P) and binder (B) is set to from 20/80 to 40/60. The coating area of the undercoat layer can thereby be adjusted with high precision, and the resistance of the undercoat layer can be reduced.
