Description
Metal-doped spinel lithium manganese oxides were successfully synthesized via co-precipitation. The synthesized Li1.05M0.05Mn1.9O4 (M = Ni, Mg, Al) had highly crystalline cubic spinel phase with the space group Fd3m, as confirmed by X-ray diffraction study. From scanning electron microscopic observation, it was found that the prepared materials had spherical morphology with high tap-density. The Li1.05M0.05Mn1.9O4 (M = Ni, Mg, Al) electrode exhibited improved cycling performance at elevated temperature. Especially, the Li1.05Al0.05Mn1.9O4 showed capacity retention of 91.5% during 100 cycles at elevated temperature (55 oC). Also the thermal stability of the Li1.05M0.05Mn1.9O4 (M = Ni, Mg, Al) was also significantly improved
