The phase transition of Li-rich cathode materials occurred from surface to internal bulk structure leads to a poor stability of cycling performance, which seriously limits the development of the materials. Herein, with a facile designed hydrothermal method, the Li-rich layered oxides microspheres with the internal spinel phase are synthesized successfully. Compared with traditional hydrothermal method, a new heterostructured material exhibits high specific capacity remarkable cycling performance (247 mA h g(-1) at 0.5 C) with high energy density (852 Wh kg(-1)). Under galvanostatic charge-discharge pattern, the discharge capacity retains about 91.5% after 300 cycles at a large current of 2 C. The full cell fabrication with artificial graphite as an anode and the synthesized heterostructured Li1.2Mn0.54Co0.13Ni0.13O2 material as cathode exhibits the favorable property and the practical applicability. We expect that this strategy is going to pave new ways to accelerate the property and application of Li-rich cathode oxides materials. (C) 2019 Published by Elsevier Ltd.
