Abstract
A polarizable electrode for use in an electrical double layer capacitor, which includes carbon fine-powders, a conductive auxiliary agent, and a binder. The tensile strength of the polarizable electrode is not less than 0.13 MPa. An amount of carbon particles displaced from the polarizable electrodes into an electrolytic solution in the electrical double layer capacitor is not more than 1.0 mg/cm . The long-term performance degradation and self-discharge caused energy losses of the electrical double layer capacitor can be reduced.
