Production Technology of Nickel Foam Metal

Nickel foam, also known as sponge metal, is a three-dimensional porous network material composed of metallic nickel. Characterized by high electrical conductivity, lightweight properties, uniform structure, excellent corrosion resistance, and high porosity, nickel Foam finds extensive applications in catalysts, fuel cells, electromagnetic shielding materials, electrode materials, transportation, and construction engineering.
The preparation methods for sponge Nickel include immersion plating, electroless nickel plating, and vacuum nickel plating. Electroless nickel plating is the predominant method for producing sponge nickel, with its primary process flow encompassing raw material preparation, conductive treatment, electroplating, calcination, reduction, and annealing. Electroless nickel plating offers advantages such as high technical maturity, operational convenience, and straightforward equipment requirements.Nickel foam produced via this method exhibits characteristics like excellent pore uniformity and superior corrosion resistance. With continuous technological advancement, the nickel foam industry is poised for accelerated growth.
Foam nickel typically consists of metallic nickel and dopants, with metallic nickel accounting for nearly 70% of production costs. Metallic nickel offers advantages such as high-temperature resistance, excellent ductility, and superior mechanical strength, making it widely applicable in industrial sectors.
Nickel foam holds broad application prospects across numerous sectors. In fuel cells, it serves as a bipolar plate modification material and electrocatalyst for solid oxide fuel cells (SOFCs), proton exchange membrane fuel cells (PEMFCs), and molten carbonate fuel cells (MCFCs). Within electrode materials, nickel foam serves as an electrode material for batteries in electronic devices, such as mobile phones and tablets. Benefiting from increasingly robust market demand, the nickel foam industry continues to expand its development potential.
