Claim 0:
1. A negative electrode active material for a secondary battery,
wherein the negative electrode active material consists of a mixture of flake-like artificial graphite and spheroidized natural graphite,
wherein the spheroidized natural graphite has an average particle diameter (D50) of 9 μm to 11 μm, and D90−D10 value is 7 μm to 9 μm, and
wherein the flake-like artificial graphite is present in the negative electrode active material in an amount of 65 to 85% by weight based on a total weight of the negative electrode active material, and the spheroidized natural graphite is present in the negative electrode active material in an amount of 15 to 35% by weight based on the total weight of the negative electrode active material.
