Abstract
An anode material includes silicon-based particles and graphite particles, the average sphericity degree of the graphite particles is A, the average sphericity degree of the silicon-based particles is B, and A and B meet: 0<B−A≤0.3. The anode material has good cycle performance, and the battery prepared with the anode material has better rate performance and lower deformation rate.
