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.
