ELECTROCHEMICAL CAPACITOR

摘要

Electrochemical capacitor The invention relates to an electrochemical capacitor(1) comprising: -a first electrode (2) intended for being connected to a positive terminal of a power source (6) during the charge of the electrochemical capacitor (1), -a second electrode (3) intended for being connected to a negative terminal of a power source (6) during the charge of the electrochemical capacitor (1), each electrode (2, 3)comprising a carbon material, and -a porous separator (5) intended to separate the first and second electrodes (2, 3) and impregnated with an almost neutral aqueous electrolyte (4) situated between the two electrodes (2, 3), the aqueous electrolyte (4) comprising a salt formed by a metallic cation and an anion.
