摘要： The present invention relates, in an aluminum electrolytic capacitor using aluminum foil as its electrode, to a method for producing safely an anode foil having a high surface-area-enlarging factor at a low cost, by adding anions, which have oxide film-forming action over aluminum surface, to aqueous solution containing chloric ions, and in this solution taking the aluminum foil as an anode, a pulse current is applied between this and a counter electrode, thus while forming an oxide film over the surface, the aluminum foil is etched at the same time, and thereby the positive electrode foil having a high surface-area-enlarging factor is obtainable.

摘要： Optimum conditions, employed in an etching process of an aluminum foil for use in an electrolytic capacitor, are selected and combined together for realizing an extension of the effective surface area of the foil. This extension also gives an enlargement of the electrostatic capacitance of the foil electrode as well as an enhancement of the mechanical strength of the foil itself, the latter had been considered to be hardly compatible with the former.

摘要： 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.

摘要： A method for electrolytically etching an aluminium foil for use as an electrode of an aluminium electrolytic capacitor is described. In the method, an aluminium foil is electrolytically etched an on the surfaces thereof in a 3 to 25% hydrochloric acid solution containing aluminium chloride by application of an AC current. The AC current has a waveform, each cycle of which consists of positive and negative half cycles and an OFF time interval between the respective half cycles at which the AC current becomes zero whereby the size of pits formed by the etching is suitably controlled.
