  "textContent": "A device for pre-lithiation including a pre-lithiation reactor sequentially divided into an impregnation section, a pre-lithiation section, and an aging section. The pre-lithiation reactor accommodates a pre-lithiation solution through which a negative electrode structure is moved. A negative electrode roll is arranged outside the pre-lithiation solution, and the pre-movement negative electrode structure is wound. A lithium metal counter electrode is arranged in the pre-lithiation solution of the pre-lithiation section, and is arranged to be spaced apart from the negative electrode structure to face the negative electrode structure moving in the pre-lithiation solution. A charging and discharging unit is connected to the negative electrode structure and connected to the lithium metal counter electrode, wherein the lithium metal counter electrode is tilted and the a separation distance between the lithium metal counter electrode and the negative electrode structure gradually increases in the moving direction of the negative electrode structure.",
