Abstract: The present invention relates to a negative electrode active material for a rechargeable lithium battery, a method for preparing the same, and a rechargeable lithium battery using the same. This invention provides a negative electrode active material for a rechargeable lithium battery, comprising a highly crystalline spherical natural graphite, wherein a Raman R value is 0.03 or more and 0.15 or less, and an internal porosity (ml/g) is 0.15 or less. The Raman R value means that the intensity ratio R (R=Id/Ig) measured by the intensity Ig of peak Pg near the 1580 cm?1 and the intensity Id of peak Pd near the 1360 cm?1 in the Raman spectrum analysis.
