The invention provides a lithium metal secondary battery negative electrode. The lithium metal secondary battery negative electrode comprises graphene foam and metal lithium compounded in the graphenefoam. The graphene foam is combined with the metal lithium, and the graphene foam is filled with the metal lithium; by taking the three-dimensional graphene foam as the framework, the liquid-state metal lithium can be automatically adsorbed in the three-dimensional graphene foam based on the lithium affinity property of the oxygen-containing functional group on the surface of reduced graphene oxide, while the three-dimensional graphene foam is formed by criss-cross flake graphene to form a porous structure, so that a relatively large specific surface area is formed, lithium can be well limited in the internal space, and volume expansion of a lithium negative electrode can be reduced; and meanwhile, the flake graphene also can influence the re-distribution of electric field in the battery,so that the lithium ion distribution on the surface of the electrode can be influenced, formation of dendritic crystal can be suppressed, improvement of the coulombic efficiency of the lithium negative electrode can be facilitated, and the obtained lithium metal negative electrode has relatively high flexibility.
