Method of rolling electrode hoop

In a rolling step of feeding an electrode hoop (1) having electrode mixture layers (3a, 3b) formed on both sides of a band-shaped core (2) made of a metal thin plate to between a pair of mill rolls (8a, 8b) for rolling, the electrode hoop (1) is fed so that side a is wound about one of the mill roll...

Summary:In a rolling step of feeding an electrode hoop (1) having electrode mixture layers (3a, 3b) formed on both sides of a band-shaped core (2) made of a metal thin plate to between a pair of mill rolls (8a, 8b) for rolling, the electrode hoop (1) is fed so that side a is wound about one of the mill rolls if the electrode mixture layers (3a, 3b) of the electrode hoop (1) have different average thicknesses, where the side a is one of the electrode mixture layers of the electrode hoop (1) having the smaller average thickness and side b is the other. This realizes a method for rolling an electrode hoop capable of making a rolled flat electrode even if the electrode mixture layers on both sides of the core have respective different thicknesses.
