Abstract
The present invention relates to an anode active material with whole particle concentration gradient for a lithium secondary battery, a method for preparing same, and a lithium secondary battery having same, and more specifically, to a composite anode active material, a method for manufacturing same, and a lithium secondary battery having same, the composite anode active material having excellent lifetime characteristics and charge/discharge characteristics through the stabilization of crystal structure as the concentration of a metal comprising the anode active material shows concentration gradient in the whole particle, and having thermostability even in high temperatures.
