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 &#x2212;3.0 V to +1.5 V.

Method for manufacturing an energy storage device

Application of a redox polymer of the poly-[Me(R-Salen)] type onto a conducting substrate is accomplished by the method of electrochemical polymerization. Said polymerization is accomplished by supplying a voltage between the substrate (that serves as an anode) and a counter electrode (that serves as a cathode), with both of them being submerged into the electrolyte containing an organic solvent and the compounds capable of dissolving in said solvent. The process is accompanied by the production of electrochemically inactive (at concentrations of no less than 0.01 mol/l) ions within the range of potentials from &#x2212;3.0 V to +1.5 V, and metal complex [Me(R-Salen)] dissolved at a concentration of no less than 5-10mol/l, (where: Me is a 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.

Electrode for energy storage devices and electrochemical supercapacitor based on said electrode

The invention is an electrochemical capacitor with its electrodes made on a conducting substrate with a layer of a redox polymer of the poly[Me(R-Salen)] type deposited onto the substrate. Me is a transition metal (for example, Ni, Pd, Co, Cu, Fe), R is an electron-donating substituent (for example, CHO&#x2014;, CHO&#x2014;, HO&#x2014;, &#x2014;CH), Salen is a residue of bis(salicylaldehyde)-ethylendiamine in Schiff's base. The electrolyte comprises of an organic solvent, compounds capable of dissolving in such solvents with the resulting concentration of no less than 0.01 mol/l and dissociating with the formation of ions, which are electrochemically inactive within the range of potentials from &#x2212;3.0 V to +1.5 V (for example, salts of tetramethyl ammonium, tetrapropyl ammonium, tetrabutyl ammonium), and a dissolved metal complex [Me(R-Salen)]. The method of using the capacitor contemplates periodically alternating the connection polarity of the electrodes, causing the electrochemical characteristics of the electrodes to regenerate.
