Abstract: A device for manufacturing a lithium band including a rolling area including two rolling cylinders, a feed-in area including a device for feeding in the rolling area with a lithium band with a first thickness, a device for feeding in two films interposed between the lithium band with a first thickness and a rolling cylinder, and a storage area including a device for collecting a lithium band having a second thickness. The lithium band with a second thickness is tensioned and rolls ensure a separation of each film off the surface of one of the rolling cylinders in a separation area located beyond a horizontal plane passing through the axis of rotation of the rolling cylinder and located opposite to the other rolling cylinder.
