Abstract

See full text

Disclosed is a porous carbon nanotube microsphere material and the preparation method and use thereof, a lithium metal-skeleton carbon composite and the preparation method thereof, a negative electrode of a secondary battery, a secondary battery, and a metal-skeleton carbon composite. The porous carbon nanotube microsphere material is spherical or spheroidal particles composed of carbon nanotubes. The spherical or spheroidal particles have an average diameter of 1 μm to 100 μm. A large number of nanoscale pores are composed of interlaced nanotubes inside the particle, and the pore size is 1 nm to 200 nm. The preparation method thereof comprises: mixing and dispersing carbon nanotubes and a solvent, and performing spray drying, to obtain the carbon nanotube microspheres. The lithium metal-skeleton carbon composite is obtained by uniformly mixing lithium metal in a melted state with a porous carbon material carrier and cooling.
