Electrode Manufacturing Method and Electrode Manufacturing System Used in Method

A method for manufacturing an electrode includes the steps of (a) laminating an active material layer on the surface of the current collector; and (b) removing a portion of the active material layer by irradiating a laser beam on the surface of the active material layer. Before irradiating the active material layer with a laser beam in step (b), a process of supplying moisture to the active material layer is performed. A system for manufacturing an electrode according to the above method is also provided.
