  "textContent": "The present invention relates to a negative electrode active material and a method for preparing the same, the negative electrode active material comprising: low-crystalline artificial graphite; and an amorphous carbon coating layer formed on the low-crystalline artificial graphite, wherein the spacing d 002 of (002) plane at the XRD measurement is 0.338 nm to 0.3396 nm. The use of the negative electrode active material of the present invention in a lithium secondary battery can form a more stable SEI layer at the time of reaction with an electrolyte, and thus can improve the initial efficiency and reversible capacity of the lithium secondary battery.",
