PURPOSE:To enhance the oxidative/reductive reaction speed of a reversible electrode, which consists of electroconductive highpolymer compound and is used to electrochemical elements such as a battery, electrochromic display element, sensor, and memory. CONSTITUTION:As a material to electrode is used a compound, in which a thiol radical is introduced to each side chain of electroconductive highpolymer, and formation of a disulphide bond between side chains is utilized to electrode reactions. Use of this type of compound to an electrode of a battery permits achieving a secondary battery having as large an energy density as 150wh/kg or more. The disulphide type compound presents slow oxidative/reactive reactions, and it is difficult to take out a large current with this solely, but combining with electroconductive highpolymer accelerates the oxidative/reductive reactions of the disulpide type compound due to the electrode catalyst action of electroconductive molecles, which together with the effect of greatly increasing the contact area substantially with the electrolyte, should enable electrolysis (charging and discharging) with large current even at room temperature. |
