1. An in-line manufacturing apparatus for a lithium metal battery, comprising:
a lithium foil tape unwinder peeling a release film on a lithium foil tape and transferring the lithium foil tape with the release film peeled off to a notching part;
the notching part forming an anode plate having an electrode tab by processing the lithium foil tape; and
a stacking part inserting a separator film between the anode plate and a cathode plate directly transferred from the notching part in a zigzag manner to alternately stack the separator film;
wherein the notching part cuts in a transverse direction by coupling a laser and a slitter, and cuts in a longitudinal direction using a slitter, to form the anode plate having the tab.
