Abstract
Preparation of a silicon composite material, and a negative electrode plate containing same, relating to the field of silicon-based composite materials. The silicon composite material comprises silicon nanoparticles, carbon nanotubes, silicon oxide, lithium oxide, and lithium metasilicate. The carbon nanotubes and the silicon nanoparticles are dispersed and cross-linked to form a three-dimensional network structure. Silicon oxide, lithium oxide, and lithium metasilicate cover the three-dimensional network structure to form secondary particles. The secondary particles and graphite are homogenized and coated according to a specific particle size ratio to prepare the negative electrode plate containing the silicon composite material and having high-capacity development, good conductivity, high coulombic efficiency, small volume expansion, and high cycling stability.
