摘要：

Rheological phase (RP) method has been successfully applied to synthesize a promising cathode material LiNi0.65Co0.25Mn0.1O2. X-ray diffraction, X-ray photoelectron spectroscopy, inductively coupled plasma and transmission electron microscope are used to investigate the structure, composition and morphology, respectively. XRD result shows that the as-prepared powder has a layered alpha-NaFeO2 structure. XPS pattern reveals that the Ni ions have valences of 2+ and 3+, and the Co and Mn are 3+, 4+, respectively. The electrode consisting of the obtained powder presents the better electrochemical properties, which is attributed to the fewer amounts of Ni2+ ions and the smaller particles. All the results suggest that the rheological phase method is a promising technique for the preparation of LiNi0.65CO0.25Mn0.1O2 cathode material of lithium-ion batteries.
