摘要： 采用氨解法制备了SnO,Sb2O3,GeO23种氧化物粉末,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其电化学性能·研究发现,这3种活性物质有较高的电化学容量,其首次放电容量分别为1520mAh/g(GeO2),820mAh/g(Sb2O3),1040mAh/g(SnO);首次充电容量分别为800mAh/g(GeO2),520mAh/g(Sb2O3),800mAh/g(SnO)·同时还发现其不可逆容量损失也较大,讨论了产生这一结果的可能原因,提出了减少不可逆容量损失的办法·

Abstract: Three powder materials, SnO, Sb2O3 and GeO2, were prepared by aminolysis, and each of them was used as an active material for the anode of lithium-ion cells. Using a constant-current cell tester to measure their electrochemical properties, the results show that their initial discharge capacities are 1520, 820 and 1040 mA·h/g and initial charge capacities are 800, 520 and 800 mA·h/g for GeO2, Sb2O3 and SnO, respectively, both are high. On the other hand, their irreversible capacities were high by experiments.
