摘要： The present application relates to a pre-lithiation method of a negative electrode for a lithium secondary battery, a negative electrode for a lithium secondary battery, and a lithium secondary battery including a negative electrode. The pre-lithiation method includes forming a negative electrode current collector layer and a negative electrode active material layer on one surface or both surfaces of the negative electrode current collector layer; forming a silver (Ag)-containing metal layer on a surface of the negative electrode active material layer opposite to a surface of the negative electrode active material layer facing the negative electrode current collector layer; and transferring lithium metal to a surface of the Ag-containing metal layer opposite to a surface of the metal layer facing the negative electrode active material layer. A thickness of the Ag-containing metal layer is 10 nm or greater and 2 μm or less.

摘要： A negative electrode for a lithium secondary battery, a method for manufacturing a lithium secondary battery, and a lithium secondary battery are disclosed. The negative electrode includes a negative electrode current collector; a negative electrode active material layer on one surface or both surfaces of the current collector; and an electrolyte solution dissolution layer on a surface of the negative electrode active material layer opposite to a surface of the negative electrode active material layer facing the negative electrode current collector layer. The electrolyte solution dissolution layer has a thickness of 0.1 μm or more and 5 μm or less. The electrolyte solution dissolution layer comprises a binder copolymer comprising a monomer unit comprising a fluoro group, and the monomer unit is present in an amount of 5 parts by weight or more and 20 parts by weight or less based on 100 parts by weight of the binder copolymer.
