Abstract
The present application relates to an anode active material and an anode, an electrochemical device and an electronic device using same. Specifically, the present application provides an anode active material, including a lithiated silicon-oxygen material and a coating layer, where there is at least a Si—O-M bond between the coating layer and the lithiated silicon-oxygen material, where M is selected from one or more of an aluminum element, a boron element and a phosphorus element. The anode active material of the present application has high stability and is suitable for aqueous processing to be prepared into an anode.
