The stabilities of the host and interfacial structure for layered LiNixCoyMn1-x-yO2 cathode materials are critical for their electrochemical properties, especially at high voltage. This study reports the synergetic effect of the Zr and Ti elements on the LiNi0.5Co0.2Mn0.3O2 cathode material (NCM523)...
