  • Surface treatment for metal-polymer laminated electrochemical cell package
    Patent number: 7867652
    Abstract: A method for preparing a metal-polymer laminate packaging material, a method for preparing a metal-polymer laminated electrochemical cell package, and an electrochemical cell package, wherein adhesion of the polymer to the metal sheet used in the packaging material and/or hydrophobicity of the metal sheet are improved. In accordance with the invention, the metal sheet is subjected to a surface treatment and thereafter coated with a polymer to form a metal-polymer laminate packaging material. Exemplary surface treatments include chromate or phosphate conversion coatings, anodization, or chemically cleaning the metal sheet with a caustic solution and/or an acidic solution.
