3D lithium-loving composite material and preparation method and application thereof, lithium metal negative electrode and preparation method and application thereof, and lithium metal battery

The invention provides a 3D lithium-loving composite material and a preparation method and application thereof, a lithium metal negative electrode and a preparation method and application thereof, and a lithium metal battery, and relates to the technical field of batteries. The Te nanosheet has relatively strong affinity with Li, and an interface energy barrier between Li and a substrate can be eliminated, so that the nucleation barrier of Li is reduced; the Te nanosheet has a relatively high transverse size, and a composite structure conductive network formed by the Te nanosheet and the rGO moderately reduces a high-curvature surface, so that nonuniformity of lithium ion flux caused by sharp protrusion is prevented, formation of lithium dendrites is avoided, and the lithium metal negative electrode can be well stabilized; li2Te formed by combination of Te and Li can be induced to form LiF-rich hybrid SEI, and LiF has the characteristics of electronic insulation and lithium ion conduction and has relatively h
