Micro Morphology

Spinel LiMn2O4 have been prepared by a flameless solution combustion synthesis, using nitrate and acetate salts as raw materials without any fuels. The effect of ignition temperature on the phase structure, micro morphology and electrochemical performance has been studied. The results indicate that spinel LiMn2O4 with single phase can be prepared successfully by the present method at the ignition temperatures of 300-800°C and calcination temperature of 600°C for 5h. The crystallinity, dispersity of the gains and electrochemical performance of the products increase with the decreasing ignition temperatures.

Liquid Combustion

Effect of nitric acid and the burning time on the liquid combustion synthesis of spinel LiMn2O4 has been studied, using lithium nitrite and Manganese acetate as raw a material. The results show that the main phases are all LiMn2O4, which can be obtained at 400-600 oC. Before modified, the impurity is Mn3O4 or Mn2O3. After modified, the impurity is only Mn3O4. The aggregation obviously reduced after adding nitric acid, it is indicated that the crystalline increased. With the increasing temperatures, the modified particle size was increased and the aggregation reduced. The initial discharge capacity and cycle stability improved at some extent too. Its first discharge capacity was 104.6, 112.8 and 117.7mAh/g synthesized at 400, 500, 600 oC, respectively, and the 30th capacity retention rate were 84.89%, 80.67% and 73.24%.
