Abstract
Official abstract text for this publication.
The method for producing an electrolytic aluminum foil of the present disclosure is a method for producing an electrolytic aluminum foil, the method including supplying an electrolytic solution in an electrolytic cell provided with a diaphragm between an anode and a cathode and depositing an aluminum foil on a surface of the cathode by electrolysis, wherein the diaphragm is made of aluminum having a purity of 85.0% or more and has a plurality of pores having an average pore diameter of 100 to 1000 μm.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for producing an electrolytic aluminum foil, the method comprising: supplying an electrolytic solution in an electrolytic cell provided with a diaphragm between an anode and a cathode; and depositing an aluminum foil on a surface of the cathode by electrolysis, wherein the diaphragm is made of aluminum having a purity of 85.0% or more and has a plurality of pores having an average pore diameter of 100 to 1000 Gm. 2 . The method for producing an electrolytic aluminum foil according to claim 1 , wherein the diaphragm is made of aluminum having a purity of 85.0% to 99.90%. 3 . The method for producing an electrolytic aluminum foil according to claim 1 , wherein the diaphragm is prepared by mixing and sintering an aluminum powder and a substance for forming pores and thereafter removing the substance for forming pores. 4 . The method for producing an electrolytic aluminum foil according to claim 1 , wherein the electrolytic solution is a molten salt containing an alkylimidazolium halide or an alkylpyridinium halide and an aluminum halide. 5 . The method for producing an electrolytic aluminum foil according to claim 1 , wherein the electrolytic solution is a molten salt containing an alkylimidazolium chloride or an alkylpyridinium chloride and aluminum chloride. 6 . The method for producing an electrolytic aluminum foil according to claim 1 , wherein the cathode is made of titanium; and the anode is made of aluminum having a purity of 95.0 to 99.9%. 7 . An apparatus for producing an electrolytic aluminum foil, comprising: an electrolytic cell in which an electrolytic solution is supplied; an anode and a cathode each to be immersed in the electrolytic solution; and a diaphragm provided between the anode and the cathode, and the apparatus depositing an aluminum foil on a surface of the cathode by electrolysis, wherein the diaphragm is made of aluminum having a purity of 85.0% or more and has a plurality of pores having an average pore diameter of 100 μm to 1000 μm.
