Abstract:
Provided is a lithium metal anode comprising a Langmuir-Blodgett films as an artificial solid electrolyte interface layer, a lithium metal battery comprising the same, and a preparation method thereof. Various ultra-thin film layers made of carbon and ceramic are formed on the surface of the LiM to serve as a stable artificial SEI layer and suppress formation and perforation of lithium dendrite and side reactions.
