Method for producing aluminum film and method for producing aluminum foil |
摘要 |
A method for producing an aluminum film by electrodepositing aluminum on a base in an electrolytic cell to which a liquid electrolyte containing a molten salt is fed includes adjusting a concentration of an additive in such a manner that a measured value of an overvoltage is within a predetermined range on the basis of a predetermined relationship between the overvoltage and the concentration of the additive added to the molten salt upon electrodepositing aluminum in the liquid electrolyte. |

1. A method for producing an aluminum film by electrodepositing aluminum on a base in an electrolytic cell to which a liquid electrolyte containing a molten salt is fed, comprising:
adjusting a concentration of an additive in such a manner that a measured value of an overvoltage is within a predetermined range on the basis of a predetermined relationship between the overvoltage and the concentration of the additive added to the molten salt upon electrodepositing aluminum in the liquid electrolyte wherein the aluminum film has a surface with an arithmetic mean roughness (Ra) of 0.2 μm to 0.5 μm or a ten-point mean roughness (Rz) of 1 μm to 5 μm. |
