Abstract: The present application provides a coated anode material and a method of preparing the same. The coated anode material has a core-shell structure, wherein the core-shell structure includes an inert core and a shell coated on the inert core, the shell comprises an anode active material, and the inert core comprises a non-active material. In the coated anode material, the anode active material of the shell is distributed over the non-active material of the inert core, and the coated anode material can overcome the volume change problem of silicon particles during lithium insertion/deinsertion to a certain extent and obtain a better cycle performance and rate performance.
