Pb-al Composite Electrode Materials Preparation Technology And Performance

Lead and lead alloys were used for hydrometallurgical industrial electrowinning copper, zinc electrowinning anode insoluble materials and as a lead-acid batteries in the grid material, but there have the defect of low mechanical strength, poor creep resistance, large resistance, the heavy quality and so on. Based on introducing the third group metal between Al and Pb, solve the compatibility between Al and Pb,prepared Al-Pb composite material by the hot dipping and appends an the casting. The interfacial organization and microstructures of Al-Pb alloys had been investigated by SEM, The multi-purpose materials measure the testing and the electrochemistry workstation, study for the influences on Al-Pb composite material's interface by interim transition-layer. By electrochemistry experiments and mechanical experiments, the feasibility and advantages of apply Al-Pb composite material to Electrode material has been verified.On basis of the related documents, technological process and parameter has been redefined by tests. And manufacture three kinds of Al-Pb compsite material, which have diffenernt interfacial structure. This paper mostly study for micstructures of interface and physical properties of Al-Pb compsite material. Application of artificial neural network technology to build the relationship between the aluminum-lead composite interface strength with the third element of transition metal ratio, hot-dip transition temperature and hot-dip crossing time, On an analysis of the interface bonding process to produce the best program in order to arrive at the best Technology program.It was found that, Al-Pb composite material has a better corrosion-resistance and a low internal resistance, and a low energy consumption, and a good mechanical properties. The experimental results show that, when the introduction of Sn or Bi as the third element of metal, aluminum and lead can be to the formation of interface-type metallurgical combine, so that the mechanical properties and improved electrochemical properties, and Bi, Sn into the situation in different proportions under different performance reflected by the establishment of artificial neural network model obtained when the third element of metal is Sn, hot dip transition temperature is 328℃, hot-dip time is 2 minutes, can be relatively well prepared aluminum laminated composite lead, which has Interface shear force of 7.7304 strength. In sum, on basis of the related documents, the processing of Al-Pb composite material and micstructures of interface had been discussed. Moreover this study provided us a new choice and reference for power material and new grid material to Lead-acid Battery.
