  • Patent number: 7888229
    Abstract: The present invention relates to methods of manufacturing an electrochemical energy storage device, such as a hybrid capacitor. The method comprises saturating a porous electrically conductive material in a solution comprising an organic solvent and a metal complex or a mixture of metal complexes; assembling a capacitor comprising the positive electrode made of porous electrically conductive material saturated with a metal complex, a negative electrode, and a separator in a casing; introducing the electrolyte solution into the casing; sealing the casing; and subsequent charge-discharge cycling of the capacitor. The charge-discharge cycling deposits a layer of an energy-accumulating redox polymer on the positive electrode. The electrolyte solution for filling the hybrid capacitor contains an organic solvent, a metal complex, and substances soluble to a concentration of no less than 0.01 mol/L and containing ions that are electrochemically inactive within the range of potentials between ?3.0 V to +1.5 V.

    Abstract: Deposition of a redox polymer of the poly-Me(R-Salen) type onto a conducting substrate by electrochemical polymerization is disclosed. Said polymerization occurs at a voltage applied between the substrate and a counter-electrode, both of which are submerged into the electrolyte. The electrolyte contains an organic solvent, compounds capable of dissolving in the solvent and forming electrochemically inactive ions at concentrations of no less than 0.01 mol/l within the range of potentials from ?3.0 V to +1.5 V, and a metal complex poly-[Me(R-Salen)] dissolved at a concentration of no less than 5×10?5 mole/liter. Me is transition metal having at least two different degrees of oxidation, R is an electron-donating substituent, Salen is a residue of bis(salicylaldehyde)-ethylenediamine in Schiff' s base). Deposition of the redox occurs in the electrolyte where the cations of the compounds have a diameter larger than that of the electrolyte cations of energy storing device containing the electrode.

  • Publication number: 20030047459
    Abstract: The present invention refers to methods for the manufacture of gas-diffusion electrodes to be used for water electrolysis and ozone production, as well as electrodes for fuel cells and other electrochemical devices. A portion of protons of an ion-exchange polymer is substituted in the channels of a channel-cluster structure of an ion-exchange polymer with cations of metal catalyst. This substitution is performed via the ion exchange process. Then said cations are electrochemically reduced in the form of metal particles of a catalyst on those areas of substrate where the latter is in contact with the channels of the channel-cluster structure of the ion-exchange polymer layer.
