description The present invention relates to a device and method for pre-lithiation of a negative electrode, the device for pre-lithiation comprising: a pre-lithiation reaction vessel which is sequentially divided into an impregnation section, a pre-litiation section, and an aging section, and which accommodates therein a pre-lithiation solution through which a negative electrode structure is moved; a negative electrode roll which is arranged outside the pre-lithiation solution, and in which the pre-movement negative electrode structure is wound; a lithium metal counter electrode which is arranged in the pre-lithiation solution of the pre-lithiation section, and which is arranged to be a preset distance apart from the negative electrode structure so as to face the negative electrode structure moving in the pre-lithiation solution; and a charging and discharging unit connected to the negative electrode structure and the lithium metal counter electrode, wherein the lithium metal counter electrode has a slanted structure so that the distance between the lithium metal counter electrode and the negative electrode structure continuously increases in the moving direction of the negative electrode structure.
