Abstract

The present invention relates to a negative electrode active material, a negative electrode for a lithium secondary battery, including same, and a lithium secondary battery. The negative electrode active material includes a silicon-based active material; and graphite, wherein the graphite includes natural graphite and artificial graphite, an absolute value of a ratio of a difference in average particle diameter (D50) size of the natural graphite with respect to the artificial graphite is 10% or less, and an absolute value of a ratio of a difference in average particle diameter (D50) size of the silicon-based active material with respect to the artificial graphite is 40% or less.
