Abstract

An apparatus for roll-pressing an electrode sheet is provided, wherein the electrode sheet has a coated portion in the middle along its width, extending in a longitudinal direction thereof and uncoated portions respectively positioned at both sides of the coated portion. The apparatus comprises: a stage on which the electrode sheet is to be placed; and a tab press roll configured to roll over one of the uncoated portions of the electrode sheet, for executing press work, wherein the tab press roll is configured, during the press work, to form a preset angle with respect to the stage, such that the tab press roll exerts less pressure at a side of the uncoated portion closer to the coated portion than the other side distant from the coated portion.
