Abstract

An anode material includes a silicon compound SiOx, where x is about 0.5 to 1.5; an oxide MeOy layer, the MeOy layer coating the silicon compound SiOx, where y is about 0.5 to 3; and a carbon layer, the carbon layer coating the MeOy layer. Me includes at least one of Al, Si, Ti, Mn, V, Cr, Co, and Zr. The surface of the MeOy layer adjacent to the carbon layer has an open pore structure, and at least part of the open pore structure is filled with the carbon layer. The anode material improves the cycle performance of the electrochemical device and significantly reduce the impedance of the electrochemical device.
