Abstract

The invention relates to a device for manufacturing a large-aperture energy storage foil with high voltage and high specific volume. The device comprises a pretreatment system, a first-time washing system, a perforating system, a second-time washing system, a broaching system, a third-time washing system, a chemical cleaning system, a fourth-time washing system, a pure water cleaning system and a drying system which are connected in sequence. The device disclosed by the invention is simple and convenient in operation, constant current type electrochemical corrosion perforating is combined with current change type electrochemical corrosion broaching, and the arrangement of the device accords with the growth process of an aperture, so that the aperture is obviously enlarged, the surface corrosion is little, the requirement of increasing corrosion aperture is reached, the specific volume of a high-voltage section product is improved, and the operating requirement of the large-aperture energy storage foil with high voltage and high specific volume is reached.

Description

technical field [0001] The invention relates to a production device for manufacturing large-aperture high-voltage high-specific volume energy storage anode foil for aluminum electrolytic capacitors. Background technique [0002] The anode foil for aluminum electrolytic capacitors must be anodized to form a certain thickness of dielectric oxide film. If the diameter of the corrosion hole on the surface of the aluminum foil is too small, the oxide film formed during the formation will fill the entire corrosion hole, which will not be effective. Spread effect. At present, the pore diameter of the energy storage foil for conventional aluminum electrolytic capacitors is generally 0.8-1.2 μm, the pore diameter is small, and the pore density is large, and the number of pores per square centimeter can reach 10. 7 One, and the pore diameter of the electrode foil for ultra-high voltage (590V, 640V) aluminum electrolytic capacitors is greater than 1.6 μm, and the pore size is much lar...
