The present disclosure relates to the technical field of materials, and provides an anode material, a method preparing the same, and a lithium-ion battery. The anode material has a core-shell structure. The anode material includes a core and a porous silicon-carbon composite layer distributed on at least part of a surface of the core. The core includes a silicon-based material, and the porous silicon-carbon composite layer includes a carbon matrix and silicon particles dispersed in the carbon matrix; the carbon matrix has pores. The anode material of the present disclosure has high conductivity and high capacity, which can effectively suppress volume expansion and improve the electrochemical performance of the anode material in a battery.
