An electrochemical capacitor includes a first electrode connected to a positive terminal of a power source during the charge of the electrochemical capacitor and a second electrode connected to a negative terminal of a power source during the charge of the electrochemical capacitor. The first and the second electrodes each have a carbon material. The electrochemical capacitor further includes a porous separator to separate the first and second electrodes and to be impregnated with an almost neutral aqueous electrolyte situated between the two electrodes. The neutral aqueous electrolyte has a salt formed by a metallic cation and an anion.
