Title: PROCESS FOR MANUFACTURING ELECTROCHEMICAL CAPACITORS
Abstract:
Process for manufacturing an electrochemical capacitor comprising, in a leaktight casing: two electrodes, namely a positive electrode and a negative electrode, a separator that separates the two electrodes, and a liquid electrolyte. The process comprises the deposition of a conductive polymer by electropolymerization on at least one of said electrodes. The electropolymerization being carried out after the two electrodes and the separator have been positioned in said casing. Furthermore, the positive or negative electrodes comprise nano-objects selected from nanopowders, elongated nano-objects, nanofibers, nanotubes, carbon nanotubes, mats of vertically aligned carbon nanotubes, graphene and graphene derivatives.
