English to French Tech/Engineering Chemistry; Chem Sci/Eng (in a patent) method of manufacturing a porous current collector

the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present
invention is to provide a method of manufacturing a porous current collector, which can fabricate a porous current collector in such a way as to fabricate alcohol-resolvable resin as an etch mask pattern by printing polyhydric alcohol on a surface of the alcohol-resolvable resin in a pattern and to form a plurality of through holes in a metal sheet using the etch mask pattern.


forming an alcohol-resolvable mask pattern layer by printing polyhydric alcohol on a surface of the alcohol-resolvable resin layer after the alcoholresolvable resin layer is formed; and

in the step of forming the polyhydric alcohol pattern layer by printing the polyhydric alcohol, a plurality of cylindrical patterns of the polyhydric alcohol pattern layer is spaced apart and formed in a surface of the alcohol-resolvable resin layer.

in the step of forming the polyhydric alcohol pattern layer by printing the polyhydric alcohol, only one of glycerin and ethylene glycol is used as the polyhydric alcohol, glycerin or ethylene glycol having viscosity of 800 to 1500 centi Poise (cps) is used, and the ethylene glycol has viscosity of 800 to 1500 cps by adding polyvinyl alcohol (PVA).
