摘要
采用共沉淀法制备了SbFeO3 和SbPbO2 5锑基复合氧化物粉末 .将其分别作为锂离子电池负极材料的活性物质 ,利用恒电流电池测试仪研究它们的电化学性能 .这两种锑基复合氧化物都有较高的电化学容量 ,SbFeO3 的可逆容量为 5 5 0mAh/g ,SbPbO2 5的可逆容量为 12 70mAh/g .这两种锑基复合氧化物的电化学容量远高于碳材料 (石墨的理论容量为 372mAh/g) ,因此 。
The two antimonic composite oxide powders, SbFeO3 and SbPbO2.5, were prepared by co-precipitation. They were used as active material of anode materials for lithium ion batteries respectively, using constant-current cell tester to test their electrochemical properties. Proved by experiments, the two antimonic composite oxides both had high electrochemical capacities. The reversible capacities of SbFeO3 were 550 mAh/g and the reversible capacities of SbPbO25 were 1270 mAh/g. They were far more than carbon materials. Therefore, the two antimonic composite oxides can be considered as candidates for the anode materials of lithium ion batteries.
