Method of Manufacturing Negative Electrode for Lithium Secondary Battery and Negative Electrode for Lithium Secondary Battery Manufactured Using the Same

Provided are a method of manufacturing a negative electrode for a lithium secondary battery, which includes: preparing a working electrode including a metal thin film; preparing a composition for forming a first solid electrolyte layer including an additive including at least one salt selected from salts represented by Chemical Formula 1 to Chemical Formula 5 and a glyme-based solvent; fabricating a half-cell including the working electrode, a counter electrode, a reference electrode, and the composition for forming a first solid electrolyte layer; forming a first solid electrolyte layer on the working electrode by operating the half-cell; and separating the working electrode on which the first solid electrolyte layer has been formed, and a negative electrode for a lithium secondary battery manufactured by the above-described method.
