    摘要: An improved etching method for enhancing the operation rate of manufacturing equipment as well as manufacturing electrode foil with a high enlarging factor in a manufacturing method for electrode foil for aluminum electrolytic capacitors, which enables one to obtain an electrode foil with a high surface enlarging factor by performing electrolytic etching, using alternating current in an acidic hydrochloric acid solution, which does not produce white powder, under the conditions of the ratio of the negative to the positive cycle part of the electric charge impressed on the aluminum foil, being in a range between 0.2 and 2.0 and the duty ratio being 51-90%.
