Title:
Electrode plate manufacturing method
Document Type and Number:
Japanese Patent JP6354698
Kind Code:
B2
Abstract:
At a first position, an active material layer material is pressurized by first and second rolls, so as to form an active material layer on the second roll. Further, at a third position on a downstream side relative to the first position but on an upstream side relative to, in a rotation direction of the second roll, a second position where a third roll is opposed to the second roll, a part corresponding to a non-formation region in the active material layer is pressurized between a removal surface of the removal portion and the second roll, thereby transferring the pressurized part to the removal surface from the second roll so as to remove the pressurized part. Further, at the second position, the active material layer is transferred onto a surface of a current collector foil from the second roll.
