NEGATIVE ELECTRODE FOR LITHIUM METAL SECONDARY BATTERY AND METHOD FOR MANUFACTURING THE SAME

The present disclosure is directed to providing improved processability by forming a protective film on the surface of lithium metal used as an electrode layer through a simple process, and to improving the cycle characteristics of a lithium metal secondary battery by forming a stable protective film. The present disclosure provides a method for manufacturing a negative electrode, including the steps of: (S1) preparing lithium metal; and (S2) dipping the lithium metal in an acid solution for 60-120 seconds to form a LiF film on the surface of lithium metal.
