摘要
以Pb-Al层状复合电极材料与传统Pb合金电极为研究对象,通过在Al与Pb合金之间引入过渡金属Sn制备出Al-Sn-Pb层状复合电极材料,与Pb合金电极对比研究了物理性能及电化学行为.测试电阻分布、重量、电极极化曲线、耐蚀性、槽电压等分析表明:与传统Pb合金电极相比,其电阻减少24%,重量减轻37.6%,电极极化电位降低2.3%,腐蚀损耗降低90.8%,槽电压降低200mV。因此ASP层状复合电极材料是一种重量轻、导电好、耐腐蚀的电极材料,有着重要的开发应用前景。
Al-Sn-Pb laminated composite electrode materials,based on the Al-Pb immiscible alloy system,was developed to the Laminated Composite Electrode Materials through the import of Sn as the third element.The difference of physical and electrochemical performance between the ASP and the Pb-alloy electrodes is compared and the influence of resistivity distribution,weight,polarization curve,corrosion resistance and tank voltage were also investigated.It is found that the ASP laminated composite electrode showed a better performance.The resistivity,weight,electrode potentials,corrosion rate were reduced by about 24%,37.6%,2.3%,90.8%,respectively.So the ASP laminated composite electrodes showed a good prospect of exploitation and utilization.
