| Abstract: | The spinel LiMn 2O 4 samples are prepared by a modified gel method of citric acid and oxalic acid.The influences of temperature on the structure of the products have been investigated.Their structures and chemical performances are studied by using X-ray diffraction,TEM,TG/DTA and charge -discharge measurements.The particle sizes are determined as between 28.5～34.2 mm by the Scherre Calculation.The LiMn 2O 4 powder obtained by heating at 750℃ for 4 hours yields a high initial capacity of 114.3 mAh/g. |
