Abstract
An anode material includes a silicon composite substrate. In the X-ray diffraction pattern of the anode material, the highest intensity at 2θ within the range of 28.0° to 29.0° is I, and the highest intensity at 2θ within the range of 20.5° to 21.5° is I, wherein 0<I/I≤1. The anode material has good cycle performance, and the battery prepared with the anode material has better rate performance and a lower swelling rate.
