ANODE MATERIAL, ELECTROCHEMICAL DEVICE AND ELECTRONIC DEVICE INCLUDING THE SAME

An anode material includes silicon-containing particles including a silicon composite substrate and an oxide MeOlayer, wherein the oxide MeOlayer is coated on at least a portion of the silicon composite substrate, wherein Me includes at least one of Al, Si, Ti, Mn, V, Cr, Co or Zr, and y is 0.5 to 3; and wherein the oxide MeOlayer includes a carbon material. The anode material has good cycle performance, and the battery prepared from the anode material has better rate performance and lower swelling rate.
