"textContent": "An anode active material for a secondary battery includes an anode current collector, and an anode active material layer formed on the anode current collector and including carbon-based active material particles and a silicon coating formed on surfaces of the carbon-based active material particles. A surface content of silicon of the anode active material layer measured by an X-ray photoelectric spectroscopy (XPS) is in a range from 3 atom% to 25 atom%. A peak intensity ratio defined as a ratio of a second peak intensity corresponding to a peak intensity at a binding energy in a range from 102 eV to 106 eV relative to a first peak intensity corresponding to a peak intensity at a binding energy in a range from 98 eV to 102 eV is in a range from 0.05 to 1.",
