Paper Title:
LiMn2O4 Powders Prepared by Solution Combustion Synthesis in Ethanol and Water Systems
  Abstract

Spinel LiMn2O4 powders have been prepared at 500 for 5h by solution combustion synthesis in water or ethanol system, using lithium and manganese acetate as raw materials and no fuels. The structure and morphology of the products have been analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The electrochemical performance has been charged or discharged in coin-type battery. XRD analysis indicates that the purity and crystallinity of the product prepared in ethanol are much better than these of the product prepared in water. SEM investigation indicates that the particles of the product prepared in ethanol are smaller and more dispersed than these of the products prepared in water. The product prepared in ethanol also exhibits better electrochemical performance than that of the product prepared in water. The initial discharge capacity of the product prepared in ethanol is 120mAh/g, and remains 110mAh/g after 20 cycles, at a current density of 50mA/g and in the voltage range of 3.2-4.35V.
