  "textContent": "The present invention relates to a negative electrode active material of a lithium secondary battery, a manufacturing method thereof, and a lithium secondary battery using the same. An embodiment of the present invention provides a negative electrode active material for a lithium secondary battery, including a graphite material including secondary particles, wherein the secondary particles are an assembly of a plurality of primary particles, the primary particles include green coke, and a ratio ((D90−D10)/D50) of a difference between a particle diameter D90 and a particle diameter D10 with respect to a particle diameter D50 of the secondary particles is 1.0 to 1.32. An embodiment of the present invention provides a method for manufacturing a negative electrode active material for a lithium secondary battery, including: manufacturing primary particles by using a carbon raw material including green coke; manufacturing secondary particles by mixing the primary particles and a binder; carbonizing the secondary particles; and manufacturing a graphite material by graphitizing the carbonized secondary particles, wherein a particle diameter D50 of the primary particles is 5.5 to 10.0 μm.",
