Notes:
It is very possible for the foam zinc materials to take the place of zinc powder and becomea new ideal material of electrode for zinc-air battery, because of its excellent three dimensionalreticulated structure, high porosity, high specific surface area and uniform quality, and was widelyused in many other fields. A novel method for preparing very porous zinc foam was proposed, inwhich the polyurethane foam as substrate was processed by degreasing process, roughening process,activation, electroless plating and zinc electrodeposition. Then, experiments were carried out toexplore the effects of the solution composition(concentration of ZnSO4)and the operation conditions (such as the interelectrode distance; current density, temperature, pH value of electroplatingsolution and so on) on the morphology of the foam zinc and the current efficiency. The optimumexperimental conditions were determined by optimizing the factors. On these conditions the foamzinc presents a three-dimensional reticular structure with high porosity, and uniformity, and theoutward appearance of the coating is bright
