ELECTROCHEMICAL CAPACITOR WITH TWO CARBON ELECTRODES HAVING DIFFERENT CHARACTERISTICS IN AN AQUEOUS MEDIUM

摘要

The invention relates to an electrochemical capacitor (1) having a first electrode (2) and a second electrode (3) each comprising carbon and an aqueous electrolyte (4) at the interface between both electrodes. The surface of the carbon of the first electrode (2) has an atomic fictionalization ratio that is multiplied by a factor of at least 2 relative to the atomic fictionalization ratio of the surface of the carbon of the second electrode (3).
