Claim 0:
1. A lithium-carbon nanoparticle-porous skeleton composite material, comprising:
a carbon nanoparticle-porous skeleton composite material comprising:
a porous skeleton comprising a carbon-based porous microsphere material with a diameter of 1 to 100 μm, wherein the carbon-based porous microsphere material is a carbon nanotube or carbon nanofiber microsphere material, wherein the carbon nanotube or carbon nanofiber microsphere material has a microsphere structure formed by entangling and agglomerating carbon nanotubes or carbon nanofibers with each other, and the interior of the microsphere is full of carbon nanotubes or carbon nanofibers, but there are nanoscale pores between the entangled and agglomerated carbon nanotubes or carbon nanofibers, so that said microsphere structure comprises nanoscale pores in its interior and on its surface, and
carbon nanoparticles distributed in at least some of the pores, and on the surface, of the carbon-based porous microsphere material, wherein the carbon nanoparticles comprise at least one selected from the group consisting of carbon black and acetylene black; and

metallic lithium distributed in at least some of the pores, and on the surface, of the carbon nanoparticle-porous skeleton composite material,
wherein the metallic lithium is 50 to 70% by mass of the total mass of the lithium-carbon nanoparticle-porous skeleton composite material and is present mainly in the pores of the composite material together with the carbon nanoparticles.
