    摘要： Disclosed is an anode active material, comprising: (a) a carbonaceous material; and (b) a carbide coating layer partially or totally formed on a surface of the carbonaceous material, the carbide coating layer comprising at least one element selected from the group consisting of metals and metalloids. An anode obtained by using the anode active material and an electrochemical device comprising the anode are also disclosed. The carbonaceous material comprises a coating layer of metal-/metalloid-carbide obtained by treating it at high temperature under inert atmosphere, wherein the coating layer has increased interfacial boding force to the carbonaceous material and thus shows minimized reactivity to lithium. The carbonaceous material as anode active material can minimize the irreversible anode capacity needed for the formation of an SEI film during the first charge/discharge cycle, thereby providing high capacity, high efficiency and significantly improved anode qualities.
