Process of making lithium motifs by differential adhesion

摘要

A film of lithium (1) is fitted between two films of plastic material (2,5) by laminating between two rollers (4). One of the two films (2) is more reactive or rougher than the other (5) allowing preferential adhesion to the first. The second film (5), which is protective, is withdrawn as soon as the shapes are cut out. The film of lithium carried by its plastic support is subsequently cut into the required shapes in order to form the electrodes for lithium cells.
