Abstract: This application relates to a tab flattening device. The tab flattening device includes: a roller configured to convey an electrode plate, a cover, and a flattening portion. The surface of the roller is in contact with the electrode plate in a contact region. The cover surrounds the contact region peripherally and includes a feed-in guide surface oriented toward the contact region. The flattening portion is disposed protrusively on the feed-in guide surface, and located opposite to a tab of the electrode plate. A tab guide surface is formed on the flattening portion. Along a feed-in direction of the electrode plate, the flattening portion is at least partially located upstream of the contact region.
