Zusammenfassung:A method of producing a negative electrode is disclosed which is capable of preventing volume expansion and structural deformation caused by pre-lithiation, maintaining proximity and contact between negative electrode active materials, preventing an increase in resistance of a negative electrode, and realizing an excellent capacity retention rate by performing pre-lithiation while pressurizing a negative electrode at a specific pressure. In addition, the method of producing a negative electrode is capable of improving quality consistency of a product and processability by performing pre-lithiation of a negative electrode in a roll-to-roll manner.
