摘要
以深海锰结核和LiOH为原料,固相反应法制备具有尖晶石结构的锂锰氧化物LiMn2O4,用XRD,SEM,TEM和XPS分析和表征合成产物。确定的最佳制备条件为Li/Mn的摩尔比为1.0,合成温度600℃,保温时间6h。
The spinel lithium manganese oxide（LiMn2O4） is prepared by solid state reaction with the raw materials of deep-sea manganese nodules and LiOH. The products are analyzed and described by means of XRD, SEM, TEM and XPS. The results show that the optimal preparation condition is molar ratio 1.0 for Li/Mn, 600°C for synthesis temperature and 6h for reaction time.
