摘要
通过化学镀中的置换还原法在水溶液中以固液混合的方式制备不同包覆量的银包铜粉,并用XRD、SEM、EDX等对银包铜粉进行表征。将其作为导电剂掺杂在钒酸铜正极材料中进行电化学测试,实验表明包覆量为20%的银包铜粉性能最佳。
By the displacement reaction,different loadings of silver-coated copper powders were prepared in the way of solid-liquid mixture in the aqueous solution,and the structures were characterized by SEM,XRD and EDX.The experimental results show that the silver coated copper powder with a loading of 20%has the best performance.
