Patent ID: 7563354

Claim:
A method of manufacturing an electrode for use in an energy-storage device, the method comprising: applying a voltage in a pulse mode between a conducting substrate serving as an anode and a counter electrode serving as a cathode, wherein both the conducting substrate and the counter electrode are submerged into an electrolyte comprising no less than 5×10 −5 mol/L of a metal complex [Me(R-Salen)] in an organic solvent and compounds capable of dissolving in the organic solvent and producing electrochemically inactive ions at concentrations of no less than 0.01 mol/L within a potential range from about −3.0 V to about +1.5 V, 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, to form on the conducting substrate an energy-accumulating layer comprising a redox polymer {poly-[Me(R-Salen)]}, wherein: the pulse mode comprises a plurality of breaks of 0V between pulses of the voltage applied, wherein the duration of the breaks is selected to allow the metal complex to diffuse into the redox polymer, and the conducting substrate comprising the energy-accumulating layer provides an electrode having a specific energy capacity suitable for use in an energy-storage device.
