Using molten salt electrolysis plating-metal bath process, Pb alloys were directly deposited on the surface of Al, and the properties of Al/Pb composite materials were studied. Using SEM and metallographic microscope, the surface morphology and combination interface of the Al/Pb composites materials were observed. Using universal testing machine, the combination strength between lead coating and matrix was tested. On the integrity, the corrosion resistance and cyclic stability of lead layer in 5 mol/L H2SO4 solution were tested. The results show that, the surface of lead layer is flat, smooth and non-holes, the thickness of the layer is uniform, and the interface of Al/Pb combination interface has obvious intermediate layer which indicates that a metallurgical combination is formed. The combination strength reaches 2.621 MPa, which can meet the requirements of lead acid battery. The integrity, corrosion resistance and stability of the lead coating prepared by this technology meet the grid requirements for lead-acid batteries, and Al/Pb composites can be used as a light-weight negative grid for lead-acid batteries.
