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.

Device for rolling a metal lithium band

A method of manufacturing a battery electrode with a discontinuous ink coating, including the following steps: make ink zones () on a first longitudinal segment () of a metallic support () and at least one additional ink zone () on at least one second longitudinal segment () of the support zones () jointly forming a support coating arranged such that at least one additional ink zone () of a second segment is located laterally facing each recessed zone () formed between two directly consecutive ink zones () of the first segment (); calendering of the metallic support () provided with its coating (), the calendering roll located on the side of the coating being permanently in contact with this coating during calendering; and separation of the segments () so as to obtain the electrode.
