▎ 摘　　要

NOVELTY - Complex formed by a network skeleton material having a lithiophilic modification layer and metal lithium (1), a porous framework which is a network skeleton with a lithium-philic modification layer interwoven by composite carbon materials, where the composite carbon material comprises a crystallized carbonaceous material (2) and an amorphous carbonaceous coating layer (3) covering the surface of the crystallized carbonaceous material, and the amorphous carbonaceous cladding layer constitutes a lithium-philic modification layer, and metal lithium filled in the pores of the porous framework. The crystalline carbonaceous material includes carbon nanotubes, graphene, carbon fibers, carbon-based metal oxide fibers, and/or carbon-based covalent organic fibers. The amorphous carbonaceous coating layer is a charred product of an organic material blended with a crystalline carbonaceous material, and the organic material is organic binder, organic filler and crosslinking agent. USE - The complex is useful in metal lithium anode of metal lithium battery (all claimed). ADVANTAGE - The complex has no pores; provides reserved space for metal lithium deposition, thus alleviating the volume expansion when it is used as a metal lithium anode; can reduce the current density on the electrode surface and reduce the growth of lithium dendrites; and is stable, and conducive to the preparation of an electrode with a long cycle life. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: method for preparing the complex; metal lithium anode comprising the complex; and metal lithium battery comprising the metal lithium anode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the complex of a network skeleton material and lithium metal with a lithium-philic modification layer. 1Metal lithium 2Crystallized carbonaceous material 3Amorphous carbonaceous coating layer
