Abstract: A method of manufacturing a positive electrode foil of an aluminum electrolytic capacitor is provided in which anodizing conditions are optimally determined and automatically set to minimize the loss of production and to produce a constant quality of the positive electrode foil. The method comprises an etching process and an anodizing process. An etched foil produced in the etching process is subjected to a constant current inspection, and then, the anodizing conditions are determined from the result of the constant current inspection. The anodizing conditions are transferred to a control panel in the anodizing process where they are automatically registered as its settings. Also, an apparatus for manufacturing the positive electrode foil is provided which has a voltage sensor connected between an output running roller and cathode electrodes in an anodizing tank. A voltage measured by the voltage sensor is fed back to a direct-current source for controlling its output voltage.

Abstract: This invention provides an apparatus for producing an electrode foil for use in aluminum electrolytic capacitors with which a high capacitance is obtained while the distortion of the foil and the leakage current can be controlled. At least two electrode plates as cathode are disposed in an electrolytic tank containing an electrolytic solution, and a direct current is supplied between an aluminum foil as anode and the electrode plates. Anodization is conducted continuously by turning the direction of the aluminum foil via rollers and conveying the foil between the electrode plates. During this treatment, the length and the position of the effective sections of the electrode plates are adjusted to keep the length to be at most two-thirds of the distance between an area near the surface of the electrolytic solution and the upper part of the bottom roller, so that the peak value of the anodizing current density appears not at the surface of the electrolytic solution but in the electrolytic solution.

Abstract: There is provided a method of producing an electrode foil for use in aluminum electrolytic capacitors. This method includes the steps of (a) introducing a predetermined length of an aluminum foil into an electrolytic solution without supplying any current; (b) supplying a current to the aluminum foil until voltage becomes constant while keeping the aluminum foil stationary therein; (c) repeating the steps (a) and (b) for another predetermined length of the aluminum foil; and (d) finally holding the aluminum foil thus obtained while applying a constant voltage thereto. According to this method, an excellent electrode foil can be obtained which provides an aluminum electrolytic capacitor with high capacitance and significantly reduced leakage current.
