Abstract

A hybrid supercapacitor, including at least one negative electrode having a statically capacitive active material, an electrochemical redox-active material, or a mixture of them; at least one positive electrode having a statically capacitive active material, an electrochemical redox-active material, or a mixture of them; at least one separator situated between the at least one negative electrode and the at least one positive electrode; and an electrolyte mixture; with the provision that at least one electrode includes a statically capacitive active material, and at least one electrode includes an electrochemical, redox-active material; the electrolyte mixture being a liquid electrolyte mixture and including at least one liquid, aprotic, organic solvent, at least one conducting salt, and at least one at least partially halogenated, aromatic compound.
