The negative electrode active material comprises a core formed by agglomerated first silicon particles; a shell formed by agglomerated second silicon particles; and an amorphous carbon coating layer surrounding the first silicon particles and the second silicon particles, wherein the shell is disposed on the core, and wherein an average particle diameter (D50) of the first silicon particles is greater than an average particle diameter (D50) of the second silicon particles, the average particle diameter (D50) of the first silicon particles being about 100 nm to about 140 nm, and the average particle diameter (D50) of the second silicon particles being about 40 nm to about 100 nm.",
