NOVELTY - Negative electrode current collector comprises a current collector substrate, a two-dimensional material layer formed on at least a portion of at least one surface of the current collector substrate and having an atomic thickness, and a metal layer formed on at least a portion of the two-dimensional material layer. USE - The negative electrode current collector is used for metal battery, preferably lithium metal battery (claimed). ADVANTAGE - The negative electrode current collector prevents decrease in capacity and output characteristics, which improves constant energy density and stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a metal battery comprising a negative electrode portion, positive electrode portion, and an electrolyte between the negative electrode and the positive electrode, where the negative electrode portion comprises the negative electrode current collector, and the negative electrode current collector comprises a current collector substrate, a two-dimensional material layer formed on at least a portion of at least one surface of the current collector substrate and having an atomic thickness, and a metal layer formed on at least a portion of the two-dimensional material layer; and a method for manufacturing the negative electrode current collector, which involves preparing a current collector substrate, forming an atom-thick two-dimensional material layer on at least a portion of at least one surface of the current collector substrate, and forming a metal layer on at least a portion of the two-dimensional material layer.
