Claims3
A antioxidant solution for lithium battery copper foil, comprising:
- hexavalent chromium;
- and
- organic compounds containing heteroatoms, wherein the heteroatoms include N, O, S or P,
- wherein based on a total weight of the antioxidant solution for the lithium battery copper foil, a content of the hexavalent chromium is 50 ppm to 1500 ppm, and a content of the organic compounds containing heteroatoms is 3000 ppm to 60000 ppm,
- wherein the organic compounds containing heteroatoms include 2-thiol benzotriazole, nitrogen-containing azoles, hydroxyethylene diphosphate, aminotrimethylenephosphonic acid, sodium ethylenediamine tetramethylenephosphate, ethanol diamine tetraacetic acid, sodium gluconate, sodium potassium tartrate or water-soluble siloxane.
