Abstract

The present invention relates to an apparatus for manufacturing a pre-lithiated electrode including: a traveling unit along which an electrode having electrode active material layers on both surfaces of an electrode current collector layer travels; a lamination unit configured to laminate a transfer laminate including a lithium metal layer and a base layer such that the lithium metal layer comes into contact with each of the electrode active material layers, at a first side surface and a second side surface of the traveling unit; a first peeling unit including a first peeling roll configured to peel the base layer from the transfer laminate at the first side surface of the traveling unit; and a second peeling unit including a second peeling roll configured to peel the base layer from the transfer laminate at the second side surface of the traveling unit, wherein among points on the electrode having a shortest distance from a center of the first peeling roll to the electrode traveling along the first side surface of the traveling unit, an upstreammost point P, and among points on the electrode having a shortest distance from a center of the second peeling roll to the electrodes traveling along the second side surface of the traveling unit, a downstreammost point Q are different from each other, and the traveling unit at the point P and the traveling unit at the point Q are located on different straight lines.
