ANODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY COMPRISING SAME

摘要

The present invention relates to an anode active material for a lithium secondary battery and to a lithium secondary battery comprising same. More specifically, the present invention relates to: an anode active material for a lithium secondary battery having a novel structure wherein Li is inserted as a transition metal layer such that the Ni oxidation number and the Co oxidation number are maintained at +3 while the Mn oxidation number is maintained at +4, thereby maintaining structural stability.
