Abstract
A method for manufacturing a negative electrode material of a lithium battery is provided. The method includes: covering a metal material and a carbon material on a surface of a silicon material; performing a thermal process for reacting the metal material with the carbon material on the surface of the silicon material thereby forming a silicon composite material and at least one projection on the surface of the silicon material, wherein a free end of the projection is extended to form a head, the silicon composite material is used as the negative electrode material of the lithium battery, the silicon composite material comprises a composite layer forming on the surface of the silicon material, and the composite layer comprises a metal silicide, a metal oxide, a silicon carbide and a silicon oxide.
