Embodiment Construction

[0012] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0013] The strip-shaped combined electrode of the present invention is to first separate the 1500×520mm electrode plate in the energizing tank into 25 strip-shaped electrode strips 1 of 50×120mm with a spacing of 8-12mm, and the two ends are welded on the stainless steel material like a ladder , and according to the distribution of the current density on the aluminum foil, a hole 2 with a diameter of 2 to 18 mm is punched on the strip electrode strip 1 (the larger the current density, the smaller the hole diameter), the hole of the first combined electrode plate is from the top From bottom to bottom, from large to small, the holes on the adjacent second combined electrode plate from bottom to top, from large to small, form a combined strip electrode plate, electrolyte solution is added to the energy tank, and aluminum foil is placed on the stri...

Abstract

The invention discloses a bar-shaped combination electrode in aluminum foil formation energy-endowing groove and preparation method thereof. The bar-shaped combination electrode is characterized in that plate electrodes of 1500*520mm in the energy-endowing groove are separated to more than two bar-shaped electrode plates of 50*120mm with distance of 10mm, two ends of the each two bar-shaped electrode plate are welded on stainless steel material like ladder, and holes with different specifications are arranged on the bar-shaped electrode plates according to distribution rule of current densityon the aluminum foil. The invention has advantages that the bar-shaped combination electrode not only can shunt, but also can make electrolyte between and round the electrodes fully cycle and temperature and concentration uniform, so that current density on the aluminum foil is reasonably distributed, and temperature and concentration of the electrolyte is easily to control in process range, thereby improving oxide film structure, increasing density, reducing oxygen omission in the film, and increasing performances of the aluminum foil.

Description

technical field [0001] The invention relates to an electrode for forming a dielectric film (hereinafter referred to as an oxide film) for an aluminum electrolytic capacitor, in particular to a strip-shaped combined electrode in an aluminum foil forming and energizing tank and a preparation method thereof. Background technique [0002] The electrodes of aluminum electrolytic capacitors are aluminum foil. The stability, electrical properties (leakage current, tgδ loss angle, etc.), life of the capacitor and the dielectric film formed on the surface of the aluminum foil (γ / -AL 2 o 3 ) is directly proportional to the quality. The dielectric film formed on the surface of the aluminum foil is based on γ / -AL 2 o 3 Mainly anodized film. The more uniform and dense the oxide film is formed, the better the electrical properties of the aluminum foil and the strength will be improved. In order to obtain the oxide film on the surface of aluminum foil, the usual method is to ap...
