Synthesis,Structure and Properties of Super Fine LiMn2O4

摘要：

In this paper,super fine LiMn2O4 powder was synthesized by mechanochemical method starting from Li2CO3 and Mn2O3. The structure,size and morphology of LiMn2O4 were explored with X-ray diffraction and scanning electron microscopy (SEM). The electrochemical properties of LiMn2O4 were studied in 2 mol/L (NH4)2SO4 solution. The result showed that pure spinel LiMn2O4 powder was prepared after 8h grinding with 3.0KW ofpower and the particle size was about 1μm. Cyclic vohammetry curve indicate LiMn2O4 electrode material has better capacitive performances.
