Abstract

It was studied that the effect of the mixing materials and the mole ratios on electrochemical properties of LiMn$_2$O$_4$LiMn$_2$O$_4$is prepared by reacting stoichiometric mixture of LiOH.$H_2O$ and MnO$_2$(EMD or CMD) and heating at 80$0^{\circ}C$ for 36h. We obtained properties of crystal structure through X-ray diffraction. LiMn$_2$O was reversible at 4.5V~3.0V and displayed two reduction and oxidation. Optimum synthesis results were obtained by reacting with LiOH.$H_2O$ and MnO$_2$(EMD) at mole ratio 1:2.
