Abstract:
A method for producing a wound electrode assembly includes steps of: overlaying electrode strips (11, 13) and separator strips (12, 14) on each other, and winding the electrode strips (11, 13) and the separator strips (12, 14) on a take-up shaft (20) while pressing a pressing member (30) against the electrode strips and the separator strips. In the winding step, the pressing force of the pressing member (30) is increased with decrease in a tension T applied to at least one of the electrode strips (11, 13) and the separator strips (12, 14).
