Abstract
A method of preparing an energy-storage device is disclosed, which involves deposition of a redox polymer of the poly-Me(R-Salen) type onto a conducting substrate by electrochemical polymerization to prepare an electrode for use in the energy-storage device. Polymerization occurs at a voltage applied between the substrate and a counter-electrode, both of which are submerged in an 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 polymer represented by the formula poly-[Me(R-Salen)] dissolved at a concentration of no less than 5×10−5 mol/L, wherein Me is a transition metal having at least two different degrees of oxidation, R is an electron-donating substituent, and Salen is a residue of bis(salicylaldehyde)-ethylenediamine. Deposition of the redox polymer occurs in an electrolyte in which the cations have a diameter that is larger than the diameter of the cations of the electrolyte employed in the energy-storage device for which the electrode is manufactured.
