But lead electrode dissolves a small portion of itself in electrolyte, and other disadvantages such as precipitation from cathode, easily changed, large resistivity, so that it consumes anode, as well as impacts anode life. Worse, lead dissolved in solution will be precipitated on cathode so as to cause lead impurity increase and reduce product quality. Thus, under condition of saving energy and reducing consumption to cater for current economic and social development, a new type of integrated performance electrode material is necessary urgently. In particular, laminated metal electrode composite materials are easily to research and develop.

Through structure morphology analysis, phase analysis and mechanical test, distribution of interface elements, diffusion layer thickness and control method were completed. The results showed that with introduction of the third element, it greatly improved combination strength of Al, Pb (tensile shear, three-point bending strength); while inter-diffusion in the three elements went up as temperature increased. Formed interface was gradually thicken. Interface width was uniform distribution just like wave. |

The results showed that although interface resistivity was slightly larger than Pb, in sum, it had been improved greatly because of the thickness of interfacial layer less than 10¦Ìm, besides introduction of Al matrix as a core. In this paper, concerning Al-x-Pb layered composite material, further research and application prospects were analyzed. A scientific method was provided to produce a new type of laminated composite electrode material. |
