    摘要: A copper foil for a negative electrode current collector of a lithium ion secondary battery enables prevention of deformation of the current collector even if the charge/discharge operation is repeatedly carried out. In a copper foil for a negative electrode current collector of a lithium ion secondary battery, a 10 mm wide test specimen composed of the copper foil is subjected to a tensile test, a maximum strain loaded on the copper foil is 30 N or higher in a region where “Value L” represented by the following expression is 0.8 or more in a strain-stress curve obtained in the tensile test where O is the starting point of the curve, PQ is the load at a point Q on the curve and EQ is an elongation at a point Q on the curve Value   L = ( area   of   triangle   OQE Q ) ( area   of   region   OQE Q )   …  ( 1 )

    摘要: An object of the present invention is to provide a method for preparing a sulfuric acid base copper electrolytic solution used for formation of an electro-deposited copper film comprising a surface excellent in smoothness and gloss when formed by using the solution just after preparation and is prepared by using mono-sulfides. To achieve the object, a sulfuric acid base copper electrolytic solution is made to contain a sulfonated active sulfur compound, the bis(3-sulfopropyl)disulfide which is recommended for formation of a glossy electro-deposited copper film. And the bis(3-sulfopropyl)disulfide contained is obtained by converting a 3-mercapto-1-propanesulfonic acid into the bis(3-sulfopropyl)disulfide in an aqueous solution of the 3-mercapto-1-propanesulfonic acid by an oxidation reaction. In the oxidation reaction, an air bubbling method is preferably used to prevent oxidative decomposition of the 3-mercapto-1-propanesulfonic acid.
