Abstract
The present invention relates to an anode for secondary battery in which an anode current collector; a buffer layer; and an active material layer are stacked sequentially. The buffer layer of the present invention has a smaller volume change during charge and discharge than the active material layer, and separation of the active material layer from the buffer layer is prevented.
