  "textContent": "A method for pre-lithiation of a negative electrode is disclosed, including the steps of: producing a lithium metal laminate which includes i) lithium metal foil; and ii) a buffer layer including carbonaceous material particles, inorganic compound particles, polymer compound particles or their combination, and coated on one surface of the lithium metal foil; producing a negative electrode including a negative electrode current collector, and a negative electrode active material layer formed on at least one surface of the negative electrode current collector; and laminating the lithium metal laminate with the negative electrode in such a manner that the buffer layer of the lithium metal laminate is in contact with the negative electrode active material layer. A lithium metal laminate used for the method is also provided. The pre-lithiation of a negative electrode that includes a buffer layer reduces the problem of rapid volumetric swelling occurring.",
