ABSTRACT

To enhance the electrochemical performances of LiMn₂O₄ at elevated temperature (55°C), we proposed a sol-gel method to synthesize LiNi_0.5Mn_1.5O₄ modified LiMn₂O₄. The physical and electrochemical performances of pristine and LiNi_0.5Mn_1.5O₄-coated LiMn₂O₄ cathode materials were investigated by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy and electrochemical measurements, respectively. The results indicated that about 4-5 nm thick layer of LiNi_0.5Mn_1.5O₄ was formed on the surface of the LiMn₂O₄ powders. The modified LiMn₂O₄ exhibited excellent storage performance at 55°C compared to the pristine one, which was attributed to the suppression of electrolyte decomposition and the reduction of Mn dissolution.
