The influence of direct current erosion on the eroded surface morphology and specific volume of electrolytic aluminum foil anode, the impurities of aluminum foil, the composition of the etching solution and the current density of DC current were studied. The results show that the erosion current density determines the size of the aluminum foil etching hole. The same hole density of aluminum foil increases with the increase of current density. The aluminum foil with less Fe and Si impurity content is advantageous to increase specific volume. Corrosive pitting corrosion solution with hydrochloric acid and sulfuric acid mixture is conducive to corrosion of the foil to obtain a higher specific capacitance; medium pressure foil corrosion, the current density of the hole is the most conducive to improve the corrosion of the foil has a higher specific capacitance; high-pressure foil Corrosion, hair hole current density is conducive to corrosion of the foil to obtain a higher specific volume
