ANODE MATERIAL, ELECTROCHEMICAL DEVICE AND ELECTRONIC DEVICE USING THE SAME

An anode material includes a silicon compound SiO, where x is about 0.5 to 1.5; an oxide MeOlayer, the MeOlayer coating the silicon compound SiO, where y is about 0.5 to 3; and a carbon layer, the carbon layer coating the MeOlayer. Me includes at least one of Al, Si, Ti, Mn, V, Cr, Co, and Zr. The surface of the MeOlayer 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.
