Effect of Nano TiO₂ Coating on Electrochemical Performance of the Li_1.2Mn_0.6Ni_0.2O₂ Cathode Materials

Abstract:

In this paper, a Li-rich cathode material Li_1.2Mn_0.6Ni_0.2O₂ is modified by the nanoscale TiO₂ coating using a simple and controllable hydrolyzation method. The effect of nanoscale TiO₂coating on the bulk structure, surface morphology and electrochemical performance are characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and electrochemical techniques, respectively. The results show that the nanosize TiO₂ can be well coated on the surface of the cathode material. The coating layers have no influence on the bulk structure of the cathode material, while they can improve the initial discharge capacity, columbic efficiency and cycling performance.
