Zusammenfassung:	Provided is a method of manufacturing a negative electrode, which includes: applying a negative electrode slurry on a negative electrode current collector and subjecting the applied negative electrode slurry to a first roll-pressing to form a negative electrode active material layer; pre-lithiating the negative electrode active material layer; and subjecting the pre-lithiated negative electrode active material layer to a second roll-pressing, wherein the negative electrode active material layer includes a silicon-based active material, and a ratio (p1/p2) of porosity (p1) of negative electrode active material layer after the first roll-pressing to porosity (p2) of negative electrode active material layer after the second roll-pressing is in a range of 1.05 to 1.65.
