SURFACE TREATMENT METHOD FOR LITHIUM METAL NEGATIVE ELECTRODE, SURFACE-TREATED LITHIUM METAL NEGATIVE ELECTRODE, AND LITHIUM METAL BATTERY COMPRISING SAME

摘要

Disclosed are a method of surface treatment of a lithium metal negative electrode, a surface-treated lithium metal negative electrode, and a lithium metal battery including the same. In the method of surface treatment of the lithium metal negative electrode, a surface of the lithium metal negative electrode is cleaned and surface-treated using dry ice blasting, thereby improving the lifetime performance of a lithium metal battery compared to that of an untreated lithium metal negative electrode and providing stable charge-discharge efficiency during the lifetime of the battery.
