Document Type and Number:
WIPO Patent Application WO/2023/195793
Kind Code:
A1
Abstract:
According to an embodiment of the present invention, provided are an electrode shape control method and an electrode manufacturing method, which comprise a molding step of emitting laser light at at least a part of an electrode sheet coated with an electrode slurry, so as to move, to an adjacent area, the electrode slurry in the area at which laser light has been emitted, thereby molding the shape of the electrode slurry. The electrode shape control method and the electrode manufacturing method, according to the present invention, can minimize capacity loss, and can control the movement direction of an electrode slurry and the movement amount of the electrode slurry in order to change the shape of an electrode.
