Abstract
A method for manufacturing an anode for a lithium secondary battery comprises: preparing a lithium transfer film by forming a lithium layer on a protection layer of a transfer film, wherein the transfer film includes a substrate and the protective layer; and preparing a negative electrode having a negative electrode active material layer formed on a current collector, and transferring the lithium transfer film by contacting and rolling the lithium transfer film onto the surface of the negative electrode material layer such that the lithium layer faces the negative electrode active material layer. The protective layer contains an acrylic resin, and the lithium layer and the protective layer are transferred onto the negative electrode active material layer.
