摘要： To provide an electrode material excellent in output characteristics and cycle property and an electrochemical device using the electrode material. The electrode material comprising polymer complex compound represented by the following graphical formula:and the electrochemical device using the electrode material. Even if such a large size ion is employed, enhanced output characteristics could be obtained in the present invention. Polymer complex compound is polarized due to an electron attracting substituent, or steric hindrance occurs due to a substituent having a branch structure so that interval of polymer complex compound formed on the electrode is increased and doping reaction. Therefore, even if using large size ions smooth and rapid doping and undoping reaction could take place.

摘要： To provide a method for producing an electrode material which is improved in energy density and is excellent in output characteristics. The present invention provides a manufacturing method for the electrode material comprising the steps of: 1) immersing a conductive material having a specific surface area of 200 to 3000m2g-1 in a complex monomer solution of a transition metal having at least two different oxidation numbers, 2) performing electro polymerization by applying pulse voltage using the conductive material as an electrode to stack the complex monomer under the condition that electrolyzation time is 0.1 to 60 second and a downtime is 10 to 600 second, and 3) forming on the surface of the conductive material an energy accumulating redox polymer layer containing polymer complex compound of transition metal formed by the stacked complex monomer, thereby accumulating energy via a redox reaction: wherein a thin and uniform electrode film is formed, namely the electrode material which is excellent in output characteristics and improves energy density is manufactured according to the method.
