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 surface treatment method for a lithium metal negative electrode, a surface-treated lithium metal negative electrode, and a lithium metal battery comprising same. The surface treatment method for a lithium metal negative electrode involves using dry ice blasting to clean and treat the surface of a lithium metal negative electrode to improve the lifetime performance of a lithium metal battery compared to one using an untreated lithium metal negative electrode, and can provide stable charge/discharge efficiency during the life of the battery.
