The invention discloses an expanded electrode applied to aluminum foil linkage enabling equipment. The expansion electrode comprises an electrode outer frame provided with a plurality of metal wires to achieve conduction of an external power source connected with the expanded electrode and the aluminum foil linkage enabling equipment; one or two electrode inner frames arranged on the electrode outer frame, wherein the metal wires extend to the tops of the electrode inner frames; an electrode net welded on the electrode inner frame, connected with the metal frame and used for electrode reaction; a forced circulation distribution pipe arranged on the inner side and the bottom of the electrode outer frame, connected with an electrolyte temperature regulating tank of the aluminum foil linkage enabling equipment through a liquid inlet pipe, and used for guiding electrolyte in the electrolyte temperature regulating tank into the expanded electrode; and an electrode expansion adjusting component arranged on the outer side of the electrode outer frame, respectively connected with the electrode outer frame and the electrode inner frame, and used for realizing expansion and contraction of the expanded electrode. The technical scheme of the invention has the beneficial effects that only the electrode part is redesigned, the original flat plate type electrode is changed into the box type expanded metal screen plate electrode, the electrode distance between the electrodes is adjustable, the electrode distance between the electrodes is reduced, the cell voltage can be reduced, and the electrodes have better current distribution uniformity.

Description

technical field [0001] The invention relates to the field of electrodes in aluminum foil linkage and energy-enabling production equipment, in particular to an expansion electrode applied to aluminum foil linkage and energy-enabling equipment. Background technique [0002] The performance of electrolytic capacitor products is closely related to the quality of the oxide film produced by aluminum foil empowerment. At present, the empowerment equipment is mainly based on linkage empowerment, and the empowerment production equipment is also high-energy electrolysis equipment. [0003] The withstand voltage value of an electrolytic capacitor is determined by the cell voltage with an energizing cell. Therefore, when producing high withstand voltage capacitors, the voltage of the aluminum foil energizing cell can be as high as thousands of volts. The cell voltage is mainly composed of electrode oxidation, reduction potential and electrolysis. The pressure drop of the electrolyte acc...
