Three-dimensional porous foam nickel-silver composite material

The invention provides a three-dimensional porous foam nickel-silver composite material. The metal silver is filled in an inner cavity of a nickel rib of a foam nickel material, the composite materialis integrally in a three-dimensional net structure, and the porosity of the composite material is 70-80%. The three-dimensional porous foam nickel-silver composite material has smaller resistance perunit area, higher tensile strength and higher elongation percentage without reducing the specific surface area of the foam nickel material. 本发明提供了一种三维多孔泡沫镍银复合材料，在泡沫镍材料的镍筋条内腔内填充有金属银，所述复合材料整体呈三维网状结构，所述复合材料的孔隙率为70～80％。本发明的三维多孔泡沫镍银复合材料，在不降低泡沫镍材料比表面积的同时，具有较小的单位面积电阻、较高的抗拉强度和较大的延伸率。
