Abstract

A cell cover for a prismatic cell, in particular a lithium-based cell, is provided. The cell cover includes a cover plate having a bottom side, a top side and at least one current-carrying cutout, at least one electrical terminal arranged at the top side, at least one current clip associated with the at least one electrical terminal, each current clip being connectable to the cover plate in a corresponding connecting region of the bottom side of the cover plate. A corresponding electrical conductor is arranged in each current-carrying cutout. The electrical terminals and respective current clip are contactable with their associated electrical conductor. The cover plate has in at least one of the connecting regions at least one connecting cutout spaced apart from the current-carrying cutout. A corresponding one of the current clips is connectable to the cover plate in a positively locking manner at the connecting cutout. The top side of the cover plate, at least in sections opposite the corresponding the bottom side connecting regions, has a substantially planar shape.
