Abstract

The present invention relates to a method for manufacturing an electrode for a lithium secondary battery, the method including the step of laminating a transfer laminate including a lithium metal layer and a carrier film on one surface of an electrode active material layer provided on at least one surface of an electrode current collector layer, wherein at least one surface of the carrier film has a maximum height roughness (Sz) in a vertical direction of 17 µm or less and an arithmetic mean roughness (Sa) of 3 µm or less, and to an electrode for a lithium secondary battery manufactured thereby, a lithium secondary battery including the same, and a transfer laminate for pre-lithiation.
