The cycle performance at high voltage up to 4.8V for spinel LiMn2O4(LMO) was investigated at 55℃.It was found that the cycle stability was dramatically improved when dimethoxydimethylsilane(DDS) was added into the electrolyte.The scanning electron microscopy (SEM) was used to study the surface morphology and the surface elements distribution of the electrodes after cycled were characterized by the energy dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS).
