Abstract
In the electropolymerization of monomers, especially pyrrole, thiophene or furan, conducting polymer films with high surface-specific capacity and favorable kinetics can be deposited for use as electrode materials in galvanic storage batteries, despite their relatively large film thickness, by impressing the selected deposition primary current i.sub.1 with at least one short current impulse having a magnitude i.sub.2 which is several times that of the primary current. This current impulse also sharply increases the deposition potential .eta..sub.1 corresponding to the primary current i.sub.1.
