  "textContent": "The present disclosure provides a negative electrode active material that can realize excellent low temperature characteristics. An negative electrode active material for a lithium ion secondary battery disclosed herein includes a carbon material that is able to reversibly occlude and release lithium ions and a carbon coating layer that is formed on a surface of the carbon material, and the carbon coating layer contains carbon atoms and phosphorus atoms. In addition, in the carbon coating layer, when a peak of a P2p spectrum measured through X-ray photoelectron spectroscopy (XPS) is subjected to waveform separation, it has a peak at a position at which the binding energy is 131 eV.",
