Abstract:
The present application relates to an anode material, and an electrochemical device and an electronic device using the same. The anode material of the present application includes: a silicon compound SiOx, where x is 0.5-1.5; an oxide MeOy layer, the MeOy layer coating at least a portion of the silicon compound SiOx, where Me includes at least one of Al, Si, Ti, Mn, V, Cr, Co or Zr, where y is 0.5-3; and a carbon nanotube layer, the carbon nanotube layer coating at least a portion of the MeOy layer. The anode material can significantly enhance the cycle performance and rate performance of the electrochemical device, and significantly reduce the impedance of the electrochemical device.
