Claim 4:
5. A method for preparing a silicon/carbon composite material with a compact structure according to claim 1, comprising:
placing a matrix in a reactor, and depositing silicon particles and a compact carbon matrix on the matrix by synchronous or alternate vapor deposition under a protective atmosphere to obtain a precursor A of a compact structure;
separating the precursor A from the matrix, and crushing the precursor A to obtain a silicon/carbon composite material precursor B;
performing carbon coating on the silicon carbon composite material precursor B to obtain a silicon/carbon composite material precursor C; and
sintering the silicon/carbon composite material precursor C at high temperature to obtain the silicon/carbon composite material with the compact structure.
