Abstract
A method of manufacturing a negative electrode for a secondary battery, which includes: forming a negative electrode structure including a negative electrode current collector and a negative electrode active material layer formed on a surface of the negative electrode current collector; providing a pre-lithiation solution in which a lithium metal counter electrode is immersed and immersing the negative electrode structure in the pre-lithiation solution so that the negative electrode structure is spaced apart from the lithium metal counter electrode; and subjecting the negative electrode structure to a pre-lithiation process, which includes an electrochemical charging process and an electrochemical discharging process performed after the electrochemical charging process, wherein a state of charge (SOC) of the negative electrode structure subjected to the pre-lithiation process is in a range of 5% to 50%.
