Abstract:
1. A method of manufacturing a hybrid capacitor comprising: (a) saturation of a porous electrically conductive material by soaking it in a solution containing: (b) assembly of a capacitor which comprises placing a positive electrode made of said porous electrically conductive material saturated with said metal complex or mixture of metal complexes obtained in step (a), a negative electrode, and a separator that separates the positive electrode and the negative electrode in a casing; introducing an electrolyte solution into the casing; and hermetic sealing of the casing, said electrolyte solution containing: an organic solvent; a metal complex able to form stacked redox polymers or a mixture of said metal complexes; and a substance soluble in said organic solvent 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; and (c) execution of no less than one cycle of charging-discharging of the capacitor.
