Abstract: An anode material includes a core-shell structured composite material. The core-shell structured composite material includes a core material, an inner shell material, and an outer shell material. The core material includes graphite particles. The inner shell material includes a continuous phase and a dispersing phase. The dispersing phase includes nano silicon particles, the continuous phase includes carbon, and the outer shell material includes lithium metal. A chemical formula of the nano silicon-based particles is SiOx, 0
