Abstract: Disclosed is an aluminum ion capacitor, including a separator, an anode and a cathode, between which the separator is interposed, and an electrolyte contacting the anode and the cathode, wherein the anode contains aluminum, the electrolyte contains aluminum ions, and an electrical double layer is formed at the cathode and intercalation and deintercalation of aluminum ions are performed at the anode. Accordingly, a supercapacitor having increased energy density can be effectively manufactured at lower cost than lithium ion capacitors, and also, the supercapacitor has high material stability and thus is not limited as to electrode configuration, and an electrode configuration that has a low manufacturing cost and is able to increase energy density and power density can be adopted.

Abstract: Disclosed is a process of treating activated carbon using carbon dioxide activation, and a supercapacitor that is manufactured using activated carbon, which is treated with carbon dioxide, as an electrode material to thus be stably operable at a high voltage. The supercapacitor according to the present invention includes improved materials of an electrode and an electrolyte constituting the supercapacitor and has optimized electrode properties so as to be stably operable even at a high voltage.
