PURPOSE: A negative active material for a lithium secondary battery is provided to improve adhesive force between a current collector and particle even if a small amount of binders is used. CONSTITUTION: A negative active material for a lithium secondary battery includes: spherical graphite obtained by coating amorphous carbon on natural graphite and plasticizing the coated material; and plate-like graphite. The average particle diameter of the spherical graphite is 15~25 micron and the average particle diameter of the plate-like graphite is 18~23 micron. |
