Electrolytic capacitor with two carbon electrodes of different nature in aqueous medium

摘要

Electrolytic capacitor (1) comprising a first electrode (2) and a second electrode (3) quecomprenden each carbon and an aqueous electrolyte (4) located at the interface of the two electrodes, caracterizadoporque the carbon surface of the first electrode (2 ) has an atomic ratio of functionalization multiplicadopor a factor of at least 2 with respect to the atomic ratio of surface functionalization of carbonodel second electrode (3).
