  "textContent": "The present invention relates to the field of battery materials, and in particular, to a lithium metal battery. The present invention provides a lithium metal battery, including a lithium metal negative electrode and a protective layer located on the lithium metal negative electrode. The protective layer includes a polymer Y, a polymer Z, and a polymer W. The polymer Y is selected from one or more of polyvinylidene fluoride and polyvinylidene fluoride-hexafluoropropylene. The polymer Z is selected from one or more of polytetrafluoroethylene and a compound represented by Formula I, and the polymer W is selected from one or more of compounds represented by Formula II and/or Formula III. The lithium metal battery provided in the present invention can form an interpenetrating polymer network structure through a chain entanglement effect between two or more polymers, thereby forming a polymer protective layer on a surface of the lithium negative electrode. The formed protective layer can implement homogeneous lithium deposition and dissolution during large-current charging and discharging, and also suppress excessive side reactions between the lithium negative electrode and an electrolytic solution.",
