摘要：

Spinel LiMn2O4 is treated on its surface with CoO1-x/ZrO2 in this paper. Metal oxide-coated spinel LiMn2O4 was investigated with respect to electrochemical characteristics. The metal oxide coating process was carried out by using the solution method. CoO1+x/ZrO2-coated spinel LiMn2O4 exhibited stable cyclic performance in the range from 3.0 to 4.4V, and it has less electrochemical impedance, polarization and capacity loss. The cell composed of the CoO1-x/ZrO2-coated spinel LiMn2O4 can be discharged at a large current density.
