The influences of aluminum cube texture on etched foil qualities and current efficiency were studied in this paper. The present results indicated that the decrease of cube texture (volume fraction) would lead to the decrease of tunnel densities on etched foils. Current efficiency changed little with cube texture and could reach up to 98%. The same current efficiency led to the same electrochemical corrosion weight loss, which caused the etched foils with a smaller tunnel density had a larger tunnel size. The same electrochemical corrosion weight loss would also lead to the etched foils produced by different cube texture foil have the same folding endurance. The etched foil produced by the foil with a better cube texture would have a larger tunnel density, which caused the capacitance of it was larger.
