Abstract

The present invention relates to a method for manufacturing a pre-lithiated negative electrode capable of suppressing formation of by-products during a pre-lithiation process, the method including the steps of preparing a negative electrode including a negative electrode active material layer having a moisture content of 800 ppm or more and provided on at least one surface of a negative electrode current collector layer; and bringing a transfer stack including a lithium metal layer and a base layer into contact with one surface of the negative electrode active material layer, with the lithium metal layer facing the one surface, and also relates to a lithium secondary battery including a pre-lithiated negative electrode manufactured therefrom.
