POLARIZABLE ELECTRODE

Title:

POLARIZABLE ELECTRODE

Document Type and Number:

WIPO Patent Application WO/2007/029742

Kind Code:

A1

Abstract:

Disclosed is a polarizable electrode for electric double layer capacitors which is excellent in gas generation suppressing effects. The surface of this polarizable electrode is covered with a thin film layer of a gel-forming organic polymer compound having a thickness of less than 5 μm. As the gel-forming organic polymer compound, there is used an organic polymer compound having a -COO- bond, preferably an acrylic polymer. Concrete examples of the gel-forming organic polymer compound include a polyalkyl methacrylate or polyalkyl acrylate which may form a stereo-complex, and a polymethyl methacrylate is preferable among them. In addition, a polyvinylidene fluoride resin can be preferably used. An electric double layer capacitor comprises a pair of polarizable electrodes and a separator sandwiched therebetween, and at least one of the polarizable electrodes is preferably the above-mentioned polarizable electrode which is excellent in gas generation suppressing effects.
