Materials Science and Engineering


LiNi0.5Mn1.5O4 was prepared under various conditions by one-step solid-state reaction in air and its properties were investigated by X-ray diffractormetry (XRD), scanning electron microscopy (SEM) and electrochemical measurement. XRD patterns show that LiNi0.5Mn1.5O4 synthesized under various conditions has cubic spinel structure. SEM images exhibit that the particle size increases with increasing calcination temperature and time. Electrochemical test shows that the LiNi0.5Mn1.5O4 calcined at 700 °C for 24 h delivers up to 143 mA · h/g, and the capacity retains 132 mA · h/g after 30 cycles.
