| 摘 要： | 利用化学沉淀法制备了Ag3BiOx,扫描电镜(SEM)和X射线衍射(XRD)测试结果表明,所制样品为Ag3BiOx,晶型良好并具有规则的纳米粒状结构.恒流放电实验测试结果表明,在中负荷放电制度下Ag3BiOx电极的实际放电容量达到342 mAh/g,且具有很高的倍率容量.通过线性扫描伏安测试进一步证明了Ag3BiOx电极可发生多个电子的还原过程,并推测了其可能的反应机理.

| Abstract: | Ag3BiOx powder was prepared by a chemical co-precipitation method and characterized by SEM and XRD techniques.The electrochemical behaviors of Ag3BiOx electrodes were studied by means of galvanostatic discharge and linear sweep voltammetry experiments.The results indicate that the specific capacity of Ag3BiOx can reach 342 mAh/g.The mechanism for this electrode was also tested and discussed by linear sweep voltammetry. |

| Keywords: | Ag3BiOx discharge capacity linear sweep voltammetry |
