"textContent": "A method of producing a negative electrode, which includes: providing a negative electrode roll on which a negative electrode structure is wound, the negative electrode structure includes a negative electrode current collector and a negative electrode active material layer on at least one surface of the negative electrode current collector; providing a pre-lithiation bath containing a pre-lithiation solution, which is sequentially divided into an impregnation section, a pre-lithiation section, and an aging section; impregnating the negative electrode structure with the pre-lithiation solution while unwinding the negative electrode structure from the negative electrode roll and moving the same through the sections. The pre-lithiation is performed by disposing a lithium metal counter electrode, which is spaced apart from the negative electrode structure and impregnated with the pre-lithiation solution, in the pre-lithiation section and electrochemically charging the negative electrode structure.",
