Abstract: The present invention relates to a negative electrode for a lithium secondary battery that can ensure a high energy density, a long-life characteristic, and stability by forming a film on a negative electrode for a lithium secondary battery and thus suppressing dendrites during electrodeposition, a method of manufacturing the same, and a lithium secondary battery using the same. The method of manufacturing the negative electrode for a lithium secondary battery according to the present invention includes preparing a sulfur dioxide-based sodium molten salt and forming a protective layer on the surface of a current collector by immersing the current collector in the sulfur dioxide-based sodium molten salt.
