(57) [Abstract] [Problem] To solve the problems of moldability, binding properties, electrical characteristics, and chemical stability of electrode paste for electric double layer capacitors, An object of the present invention is to provide an electrode for an electric double layer capacitor, a non-aqueous or aqueous electric double layer capacitor having excellent oxidation-reduction resistance, solvent resistance, and heat resistance. SOLUTION: By using a polymer containing a repeating structural unit having an amide structure, for example, a polymer of N-vinylacetamide as a binder for a polarizable electrode paste, the stability as a paste is improved and obtained. Excellent adhesion to current collectors at electrodes, binding properties of polarizable electrode materials, electrochemical stability, and affinity with electrolytes.By using such electrodes, it can be operated with high capacity and high current. Completed a non-aqueous or aqueous electric double layer capacitor with long life and excellent reliability. |
