Abstract: Disclosed are a lithium anode surface modification method for a lithium metal battery and a lithium metal battery. The modification method comprises the following steps: immersing, in a dry protective gas atmosphere, a lithium metal anode in a fluorine ion-containing liquid, or dropping a fluorine ion-containing liquid on a surface of the lithium metal anode; after fluorination and removal, a protective layer rich in lithium fluoride is formed on the surface of the lithium metal anode, and a lithium metal-coated lithium metal anode is obtained.
