Abstract: Disclosed is a method of manufacturing a negative electrode, wherein a negative electrode structure is electrochemically charged while being pressed with a plurality of pre-lithiation rolls in performing pre-lithiation of the negative electrode structure by a roll-to-roll method, and here, the pressing pressures of the plurality of pre-lithiation rolls are increased in a movement direction of the negative electrode structure. Since the pressing pressures are increased in the movement direction of the negative electrode structure, volume expansion, structural deformation, and damage to an active material due to the pre-lithiation may be prevented, and at the same time, the pre-lithiation may be performed uniformly, and thus it is preferable for improving lifespan characteristics of a negative electrode.
