Abstract
<p>A LiCoO<sub>2</sub>/LiNi<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>O<sub>2</sub> composite was prepared by the combination of mechanical ball milling and heat treatment. The as-prepared LiCoO<sub>2</sub>/LiNi<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>O<sub>2</sub> composite was characterized by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray Spectroscopy. The LiCoO<sub>2</sub>/LiNi<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>O<sub>2</sub> composite was utilized as cathode material for lithium-ion batteries. Compared with the milled LiCoO<sub>2</sub>/LiNi<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>O<sub>2</sub> composite, the LiCoO<sub>2</sub>/LiNi<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>O<sub>2</sub> 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 LiNi<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>O<sub>2</sub> were co-doped for the LiCoO<sub>2</sub> during high temperature, resulting in improving the electrochemical properties of the LiCoO<sub>2</sub>/LiNi<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>O<sub>2</sub> composite.</p>
