Abstract
An anode material includes a silicon composite substrate, wherein the Dv50 of the silicon composite substrate is from 2.5 μm to 15 μm, and the particle size distribution of the silicon composite substrate meets 0.1≤Dn10/Dv50≤0.6. The anode material has good cycle performance, and the battery prepared with the anode material has good rate performance and lower swelling rate.
