Abstract
A facile method has been developed to synthesize Al2O3-coated LiNi0.8Co0.2O2 cathode materials. The sample was characterized by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and energy dispersive analysis of X-rays (EDAX). Electrochemical tests show that the cycling stability of LiNi0.8Co0.2O2 at room temperature is effectively improved by Al2O3 coating. The differential scanning calorimetry (DSC) and high temperature (60 °C) cycling tests indicate that Al2O3 coating can also improve the thermal stability of LiNi0.8Co0.2O2, which is attributed to that the coating layer can protect the LiNi0.8Co0.2O2 particles from reacting with the electrolyte.
