Abstract:
Pb-Sn-Al laminated composite electrode materials,based on the Pb-Al 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 composite electrode materials and the Pb-alloy electrodes is compared and the influence of resistivity distribution,mass,polarization curve,corrosion resistance and tank voltage were also investigated.It is found that the Pb-Sn-Al laminated composite electrode showed a better performance.The resistivity,mass,electrode potentials,corrosion rate were reduced by about 24%,37.6%,2.3%,23.2%,respectively.So the Pb-Sn-Al laminated composite electrodes showed a good prospect of exploitation and utilization.
