Lithium-rich manganese-based oxide Li1.2Ni0.13Co0.13Mn0.54O2 nanorods and polyhedrons have been successfully prepared using precursor β-MnO2 as sacrificial templates at a calcination temperature of 750, 800, 850 or 900 °C. X-ray diffraction (XRD) scanning electron microscope (SEM) measurements show that the elevated temperatures help to improve layered structure average particle size target products. Rod-like can be obtained low (i.e., 750 800 °C), which becomes polyhedral As lithium ion battery cathodes, °C shows highest discharge capacity 239.2 mA h g−1 20 g−1, stable 92.8 1000 g−1. The good electrochemical performances sample should attributed better crystal and/or more appropriate compared with those other samples.
