  "textContent": "An electrolyte composition and a solid polymer electrolyte for electric double-layer capacitors are each composed of a polyurethane polymeric compound and an ion-conductive salt. A substituent having a large dipole moment has been introduced onto the polyurethane molecule, as a result of which the polyurethane polymeric compound exhibits a high dielectric constant and retains the ability to dissolve an ion-conductive salt to a high concentration, has excellent adhesive properties that enable it to firmly bond large surface area materials and conductive materials, and moreover has an interfacial impedance comparable to that of electrolyte solutions. The invention is also directed at a polarizable electrode-forming composition and a polarizable electrode composed primarily of a polyurethane polymer compound, a large surface area material and a conductive material. The invention additionally discloses a high-performance electric double-layer capacitor arrived at using the above compositions and components.",
