Abstract
Disclosed is a novel cathode active material for secondary batteries. More specifically, disclosed is a cathode active material for secondary batteries that reduces deintercalation of oxygen from a crystal structure of Li2MnO3 at a high voltage of 4.3V to 4.6V through incorporation of excess lithium in a transition metal cation layer.
