摘要：
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 degrees C and calcination temperature of 600 degrees C for 5h. The crystallinity, dispersity of the gains and electrochemical performance of the products increase with the decreasing ignition temperatures.
