Abstract

An anode for a lithium secondary battery includes an anode current collector, and an anode active material layer formed on the anode current collector and including an anode active material, a binder and a nitrate. 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. 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 and a thickness of the anode active material layer.
