Abstract

Abstract:

Li-rich layered cathode materials xLi[Li_1/3Mn_2/3]O₂-(1-x)LiNi_5/12Mn_5/12Co_2/12O₂(0≤x≤0.8)were prepared via spray-dry method. X-ray diffraction(XRD), high resolution transmission electron microscopy(HRTEM), X-ray photoelectron spectroscopy(XPS), electrochemical impedance spectroscopy(EIS) and charge-discharge tests were carried out to investigate the influence of the amount of Li₂MnO₃ component on the structure and electrochemical properties of the materials. It is found that the micro-structure changes with the increase of Li₂MnO₃ content in composition. In the case x≤0.2, the crystal structure of material is similar to parent material LiNi_5/12Mn_5/12Co_2/12O₂. When x≥0.4, the materials show Li₂MnO₃-like structure. And the two structures co-exist in sample of x=0.3. HRTEM observations reveal that the arrangement of transition mental ions in the internal structure transfer from long-range order to long-range disorder and short-range order. As the x value increases from 0.1 to 0.8, the discharge capacity of material increases gradually when x≤0.6, and decreases gradually when x>0.6. It is reasonable considering the increase of charge transfer resistence detected by EIS. As a result, when x=0.6, the material exhibts the highest discharge capacity, which is about 260 mA·h/g at room tempreature and 304 mA·h/g at high tempreature(50℃). The EIS research shows that the micro-structural transformation from order to disorder increases the charge transfer resistance of material, thus yield poor electrochemical performances.
