Abstract:	LiMn2O4 spinel cathode materials were modified with 2 w% Li-M-PO4 (M=Co, Ni, Mn) by polyol synthesis method. The phosphate surface-modified LiMn2O4 cathode materials were physically characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). The charge-discharge test showed that the cycling and rate capacities of LiMn2O4 cathode materials were significantly enhanced by stabilizing the electrode surface with phosphate.
