Embodiment 1
[0046] The first step, aluminum sheet pretreatment
[0047] Anneal the high-purity aluminum foil with a thickness of 0.3mm and a purity of 99.999% in a protective atmosphere filled with argon or nitrogen to prevent oxidation of the aluminum sheet.
[0048] The annealed aluminum foil is pretreated successively by cleaning, removing the natural oxide film on the surface, and polishing.
[0049] Cleaning: Put the aluminum foil in acetone and absolute ethanol successively, and ultrasonically clean it with a 1000w ultrasonic cleaner for 5 minutes.
[0050] Removing the natural oxide film on the surface: Soak the cleaned aluminum foil in 10%wt NaOH solution for 15min, and then rinse it with deionized water.
[0051] Polishing treatment: use graphite as the cathode, and aluminum foil from which the natural oxide film has been removed on the surface as the anode, and polish in the polishing solution for 5 minutes with a DC voltage of 15V. The polishing liquid preparation ratio is th...
