Anode for secondary battery and lithium secondary battery including the same

An anode for a lithium secondary battery, comprising:

• an anode current collector;
• and
• an anode active material layer formed on the anode current collector, the anode active material layer comprising an anode active material, a binder and a nitrate,
• wherein a concentration gradient of the binder in a thickness direction from a top surface of the anode current collector to a top surface of the anode active material layer is 0.1 wt %/μm or less, and
• the concentration gradient of the binder is calculated from contents of a dye adsorbed to the binder measured at multiple points along a line in the thickness direction on a cross-section of the anode active material layer through an SEM-EDS (scanning electron microscope-energy dispersive spectroscopy) analysis and a thickness of the anode active material layer.
