Abstract
An anode active material for use in a lithium secondary battery including a mixture of graphite I that has, according to X-ray powder diffraction, dof not smaller than 0.3354 nm and not greater than 0.337 nm, Lc(004) of smaller than 100 nm, La(110) of not smaller than 100 nm, and a half width of the peak of a plane (101) at a diffraction angle (2θ) of 44 degrees to 45 degrees of not smaller than 0.65 degree and another graphite so as to have, according to X-ray powder diffraction, dof not smaller than 0.3354 nm and not greater than 0.337 nm, Lc(004) of not smaller than 80 nm, La(110) of not smaller than 100 nm, and a half width of the peak of a plane (101) at a diffraction angle (2θ) of 44 degrees to 45 degrees of not smaller than 0.5 degree.
