Abstract
Regular spherical chromium doped spinel lithium manganese oxides (LiCr0.04Mn1.96O4) with an average particle size of about 20 µm were prepared by the slurry spray drying process. The materials were compared with non-spherical LiCr0.04Mn1.96O4 materials prepared by the common drying process, and all materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), laser particle analyzer and Brunauer-Emmett-Teller (BET) specific surface area test. Electrochemical performances of these cathode materials were studied by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and Li/LiCr0.04Mn1.96O4 battery test. The results show that the spherical active material is single spinel structure, compact, and with narrow particle size distribution and low BET specific surface area. Compared with the non-spherical material, the spherical material prepared by the spray drying process shows a lower electrochemical impedance, a fewer electrochemical polarization and a better charge/discharge rate capability and capacity retention at elevated temperatures.
