ABSTRACT:
An electrolytic capacitor (1) includes a first electrode (2) and a second electrode (3) each including carbon and an aqueous electrolyte (4) situated at the interface of the two electrodes. The carbon surface of the first electrode (2) has an atomic degree of functionalization which is at least twice that of the carbon surface of the second electrode (3).
