摘要: A method for producing a lithium metal negative electrode structure including the steps of: (a) forming a lithium metal layer on a portion of one side or both sides of a current collector, wherein a non-coated portion of the current collector, on which a tab will be formed, is included on one side of the current collector, and wherein a stepped part is present between the non-coated portion of the current collector and the coated portion of the lithium metal layer; (b) coating and curing a photocurable material, or attaching an insulating tape, onto the stepped part between the non-coated portion of the current collector and the coated portion of the lithium metal layer; and (c) punching the result of step (b) into a unit electrode to produce the lithium metal negative electrode structure.
