The silicon carbon composite anode material includes a silicon-based active particle, a conductive material, and a carbon coating layer, where the carbon coating layer is present on surface of the silicon-based active particle and/or the conductive material; and a semi-width of an X-ray diffraction angle (2θ) of the silicon-based active particle on a crystal face (111) is greater than or equal to 0.5 degree when X-ray diffraction of the silicon-based active particle is tested with CuKα ray. The silicon carbon composite anode material and preparation method thereof, and a lithium ion battery can effectively inhibit volume expansion of anode material and improve cycle performance of battery.",
