<p><P>PROBLEM TO BE SOLVED: To provide an electrochemical capacitor capable of improving a discharge characteristic. <P>SOLUTION: A positive electrode 11 and a negative electrode 12 are laminated on each other through a separator 13. The positive electrode 11 includes a positive electrode active material layer 11B on one surface of a positive electrode collector 11A, and the negative electrode 12 includes a negative electrode active material layer 12B on one surface of a negative electrode collector 12A. Each of the positive electrode active material layer 11B and the negative electrode active material layer 12B contains an ionic liquid and a polymer compound along with the active material. Since the ionic liquid is retained by the polymer compound in each of the positive electrode 11 and the negative electrode 12, discharge capacity is prevented from being easily degraded. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
