<P>PROBLEM TO BE SOLVED: To provide a polarized electrode low in internal resistance, high in tensile strength, and excellent in electrolyte impregnation ability. <P>SOLUTION: A polarized electrode has an electrode active material, a conductive material, a binder, and an isothiazolin compound. The electrode includes the isothiazolin compound in a ratio of 0.001-2.0 pts.mass relative to 100 pts.mass of the binder. The binder includes a polymer containing 10-60 pts.mass of a (metha)acrylonitrile unit, 35-85 pts.mass of a butadiene unit, and 0.5-10 pts.mass of an ethylenic unsaturated carboxylic acid unit in 100 pts.mass of it. <P>COPYRIGHT: (C)2012,JPO&INPIT |
