Abstract:
A method for making a modified current collector of a lithium ion battery is provided. In the method, the modifier and a metal plate are provided. The modifier is a mixture of a phosphorus source having a phosphate radical, a trivalent aluminum source, and a metallic oxide provided in a liquid phase solvent. The modifier is coated on a surface of the metal plate to form a coating layer. The coated metal plate is heat treated to transform the coating layer into a protective film formed on the surface of the metal plate.
