Electrolytic capacitor for e.g. aircraft, has aqueous electrolyte situated at interface of electrodes, where one electrode has surface with operating rate multiplied by factor equal to two, with respect to rate of other electrode surface
The capacitor (1) has an aqueous electrolyte (4) situated at an interface of two carbon electrodes (2, 3), where the aqueous electrolyte is an acid or base aqueous solution containing sulfuric acid. The electrode (2) has a carbon surface with an atomic operating rate multiplied by a factor equal to 2, with respect to an atomic operating rate of a carbon surface of the electrode (3), where the electrodes contain respective Super50(RTM: activated carbon) and Maxsorb(RTM: activated carbon). A porous separator (5) is arranged in the electrolyte between the electrodes. The activated carbon of the electrode (2) is oxidized by an acid solution i.e. nitric acid aqueous solution. The carbon surfaces are processed by nitrogenous, sulfurated, oxygenated and phosphorated functions. Independent claims are also included for the following: (1) a method of manufacturing an electrolytic capacitor (2) an electric circuit comprising an electrolytic capacitor.
