Abstract
The present application relates to an anode active material and an anode, an electrochemical device and an electronic device using the same. Specifically, the present application provides an anode active material, including a lithiated silicon-oxygen material and a coating layer, where the coating layer and the lithiated silicon-oxygen material at least have one or more structural units selected from formulaeCF,CHFandCHtherebetween, where a, b, and c are integers greater than or equal to 6. The anode active material of the present application has high stability and is suitable for being subjected to aqueous processing to obtain the anode.
