Abstract
The present disclosure provides an anode for a secondary battery, including: an electrode current collector; a first coating layer formed on the electrode current collector and including an anode active material, a first aqueous binder and a conducting material; and a second coating layer formed on the first coating layer and including a second nonaqueous binder. Since the anode of the present disclosure can reduce volume change of the anode active material, a lithium secondary battery including same may have improved cycle characteristics.
