中文摘要	This paper presents the preparation of LiNi0.5Mn1.5O4 and aluminum (Al) doped LiNi0.5Mn1.5O4 hollow microspheres as 5 V cathodes using monodisperse MnCO3 microspheres as precursor and template, which were synthesized using MnSO4 center dot H2O, NaHCO3 and ethanol in water at room temperature. XRD and morphology characterization results indicated that the as-prepared LiNi0.5Mn1.5O4 and Al doped LiNi0.5Mn1.5O4 were both spinel structure, and have particle sizes of 2-3 mu m. The cathode electrochemical properties of LiNi0.5Mn1.5O4 and Al doped LiNi0.5Mn1.5O4 hollow microspheres (as 5 V cathodes) were evaluated and compared by galvanostatic cycling (GC) vs. Li/Li+ at the current rate 1C in 2.7-4.8 V. The specific initial capacities of all samples were in the range of 70-120 mA h g (1). Compared to undoped LiNi0.5Mn1.5O4, Al doped LiNi0.5Mn1.5O4 hollow structures can effectively improve discharge capacity (up to 140 (+/- 5) mA h g (1)) and cycling stability (70% capacity retention after 200 cycles) as high voltage cathode materials.
