Abstract

See full text

Disclosed is an anode active material for lithium secondary batteries that includes natural graphite particles consisting of spherical particles of agglomerated graphite sheets, outer surfaces of which are not coated with a carbon-based material, wherein the surfaces of the particles have a degree of amorphization of at least 0.3 within a range within which an R value [R=I1350/I1580] (I1350 is the intensity of Raman around 1350 cm−1 and I1580 is the intensity of Raman around 1580 cm−1) of a Raman spectrum is in the range of 0.30 to 1.0.
