and electroless nickel plating is its main preparation method.

Nickel foam, also known as sponge metal, is a three-dimensional porous network structure material composed of metallic nickel. Nickel foam has the characteristics of high conductivity, lightweight, uniform structure, good corrosion resistance, and high porosity. It is widely used in catalysts, fuel cells, electromagnetic shielding materials, electrode materials, transportation, construction engineering and other fields. Nickel…
