Abstract: The present disclosure provides a roller-press apparatus, which comprises: an unwinding mechanism around which an electrode plate to be rolled is wound, the electrode plate has a foil and a coating layer, the foil has at least a coated area and a blank foil area, the foil is provided with the coating layer at the coated area and is not provided with the coating layer at the blank foil area; a rolling mechanism; and a stretching mechanism. The stretching mechanism comprises: two guide rollers; and an uneven roller positioned between the two guide rollers, and forming a wrap angle with the two guide rollers, the uneven roller matches the electrode plate in size to allow a protruding portion of the uneven roller to act on the foil at the blank foil area, so as to allow the foil at the blank foil area to be plastically deformed.
