Super-capacitor comprising positive and negative electrodes made of a p- doped electron conductive polymer and an electrolyte containing an organic redox compound
A super-capacitor comprising a positive electrode, a negative electrode, both made of a p-doped electron conductive polymer, and an electrolyte. The electrolyte comprises an organic redox compound soluble in the electrolyte in an amount of at least 10.sup.-3 mole per liter. The redox potential of the redox compound lies in a non-capacitive region of the electron conductive polymer. The redox compound is reduced in a reversible manner at the negative electrode when the potential of the negative electrode is equal to or less than the redox potential of the redox compound, and the redox compound is oxidized in a reversible manner at the positive electrode when the potential of the positive electrode is equal to or more than the redox potential of the redox compound.
