Abstract

This invention belongs to the field of lithium battery technology and relates to a lithium anode with a LiF-Li3N multifunctional interface layer and its preparation method. The lithium anode with the LiF-Li3N multifunctional interface layer is formed by coating a lithium metal surface with a pentafluorobenzamide solution. The lithium anode with the LiF-Li3N multifunctional interface layer prepared by the method of this invention can protect the lithium anode, improve the safety of all-solid-state lithium batteries, and effectively suppress the growth of lithium dendrites when used in all-solid-state lithium batteries, achieving uniform lithium deposition and stripping, and improving the cycle life of all-solid-state lithium batteries.
