Abstract
The present disclosure refers to a lithium secondary battery comprising LiNiOin a cathode active material so as to improve the phenomenon that the capacity retention ratio decreases at initial cycles when using an anode active material selected from the group consisting of Si, SiC, SiO(0<x<2), Sn, SnO, Sb, Ge and a mixture thereof. The lithium secondary battery according to the present disclosure can substantially improve the decrease of a capacity retention ratio during initial cycles.
