N2 - A LiCoO2/LiNi0.8Co0.1Mn0.1O2 composite was prepared by the combination of mechanical ball milling and heat treatment. The as-prepared LiCoO2/LiNi0.8Co0.1Mn0.1O2 composite was characterized by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray Spectroscopy. The LiCoO2/LiNi0.8Co0.1Mn0.1O2 composite was utilized as cathode material for lithium-ion batteries. Compared with the milled LiCoO2/LiNi0.8Co0.1Mn0.1O2 composite, the LiCoO2/LiNi0.8Co0.1Mn0.1O2 composite after heat treatment exhibited superior performance, including in an increased coulombic efficiency, better capacity retention and enhanced rate capability. The present work demonstrated that Ni and Mn from LiNi0.8Co0.1Mn0.1O2 were co-doped for the LiCoO2 during high temperature, resulting in improving the electrochemical properties of the LiCoO2/LiNi0.8Co0.1Mn0.1O2 composite.
