Pretreatment method for metal aluminum and copper current collectors for secondary batteries

摘要

The present invention treats the aluminum and copper current collectors used as current collectors in a lithium secondary battery with an acidic aqueous solution, a basic aqueous solution or a neutral aqueous solution, thereby increasing the surface area and improving adhesion to the mixed slurry, thereby providing excellent charge and discharge characteristics. Eggplant relates to a current collector for the production of a lithium secondary battery.
