Abstract
An aluminum electrolytic capacitor including an anode electrode, and a method for producing the anode electrode. The method includes providing an aluminum electrolyte including an ionic liquid and an aluminum salt, galvanically deposing an aluminum on an aluminum foil formed from the aluminum electrolyte, and anodically oxidizing a surface of the aluminum foil. The ionic liquid includes a pyrrolidinium cation and a halogenide. The aluminum electrolyte includes 50-70 mol. % of the aluminum salt based on a total substance amount of the ionic liquid and the aluminum salt. The galvanic deposition includes and is based on a deposition temperature ranging from 20° C. to 100° C., a current density ranging from 1 to 100 mA/cm, an applied potential ranging from −0.1 V to −1.0 V based on a potential of an aluminum reference electrode, and a deposition rate ranging from 1 to 50 μm/h.
