Document Type and Number:
WIPO Patent Application WO/2022/060021
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a lithium metal electrode, a lithium metal electrode manufactured thereby, and a lithium metal electrode comprising same and, more particularly, to a method for manufacturing a lithium metal electrode, comprising the steps of: (a) applying fluoroethylene carbonate on at least one surface of a lithium metal layer; and (b) forming a lithium fluoride protective layer on at least one surface of the lithium metal layer by rolling the lithium metal layer coated with the fluoroethylene carbonate.
