Title:
COMPOSITE CURRENT COLLECTOR MANUFACTURING METHOD AND MANUFACTURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/051475
Kind Code:
A1
Abstract:
A composite current collector manufacturing method and manufacturing device. By means of selective pretreatment, an active area is formed in the middle portion of the surface of a base material belt, and blank areas will not be treated during the pretreatment process, thus the edges on the two sides of the base material belt will not be damaged. Moreover, during the process of forming a metal layer, only the active area is operated, and no metal layer will form on the blank areas. However, when the metal layer is formed, damages such as piercing to the base material belt often occur at the edge position of the metal layer.
