A method for preparing an amorphous silicon powder for an anode material of a lithium-ion battery is disclosed. The amorphous silicon powder is prepared by reducing an oxide of silicon, wherein an X-ray diffraction peak of an amorphous silicon material is weak, and the amorphous silicon material is of an amorphous structure. A structural formula of the oxide of silicon is SiO, wherein 0&#x3c;x&#x2264;2. The reduction refers to vapor phase reduction, a vapor phase reduction atmosphere is a mixed gas of hydrogen and carbon monoxide, a reduction temperature ranges from 100&#xb0; C. to 700&#xb0; C., and a reduction time ranges from 2 h to 72 h.
