"textContent": "A method for pre-lithiation and pre-sodiation of a negative electrode, including the steps of: preparing a negative electrode including a negative electrode current collector, and a negative electrode active material layer on at least one surface of the negative electrode current collector. Then, applying and drying a first composition containing a lithium metal powder, a polymer binder and a dispersion medium onto the negative electrode active material layer to form a lithium metal layer. Next, applying and drying a second composition containing a sodium metal powder, a polymer binder and a dispersion medium onto the lithium metal layer to form a sodium metal layer. Then, dipping the negative electrode having the lithium metal layer and the sodium metal layer in an electrolyte for pre-lithiation and pre-sodiation. A pre-lithiated and pre-sodiated negative electrode obtained by the method and a lithium secondary battery including the same are also disclosed.",
