Title:
A manufacturing method of electrolysis aluminum foil, an electrode for batteries using it, an accumulation-of-electricity device, and electrolysis aluminum foil
Document Type and Number:
Japanese Patent JP6260860
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electrolytic aluminum foil which can stabilize discharging and charging efficiency.SOLUTION: The electrolytic aluminum foil is provided which has a base material peeling surface and a precipitation surface, and has roughness Ra of both sides being in the rage of 0.1-0.6 μm. The electrolytic aluminum foil is obtained by applying a current between a cathode drum and an anode plate, partly soaked in plating solution for foil formation, and peeling aluminum electrolytic membrane formed on the cathode drum. The base material peeling surface keeps the surface property that the surface form of the cathode drum is copied. The precipitation surface keeps the surface property of the electrolytic membrane formed with the plating solution for foil formation.
