Abstract: Provided is a method for processing lithium metal of a negative electrode in an electrode assembly. The processing method includes: a supply step of separating a first raw material composed of lithium metal having a first protective layer bonded to one surface thereof and a second raw material composed of a second protective layer to supply the raw material so that the lithium metal is positioned between the first protective layer and the second protective layer; a cutting step of pressing the supplied raw materials using a cutter on the first and second protective layers to cut the lithium metal; and a recovery step of separating the first raw material and the second raw material after cutting to recover the raw material. The method for processing lithium metal according to an embodiment of the present invention is effective in processing lithium metal extending in the longitudinal direction applied as a negative electrode to a stack-folding type electrode assembly, and can produce processed lithium metal with high reliability.
