Ultra-thin nickel foam, 0.5mm/0.1mm thickness, customizable for die-cutting and punching

Nickel foamis an excellent sound-absorbing Material with a high sound absorption coefficient at high frequencies; its low-frequency sound absorption performance can be enhanced through structural design.
Nickel Foam also serves as an electrode material for cadmium-nickel and nickel-metal hydride batteries.

Production Process:
A process for preparing nickel foam via electrodeposition technology has been successfully developed through experimentation. The substrate material used is porous open-cell foam plastic. Conductive layers can be prepared using three methods: electroless nickel plating, vacuum nickel plating, and immersion in conductive paste (palladium sol, submicron graphite emulsion, etc.) to form the conductive layer. After pre-nickel plating, thick nickel can be electroplated in a standard sulfate nickel plating electrolyte. Subsequent sintering, reduction, and annealing processes yield high-performance three-dimensional network foam nickel materials.

Applications:
1. Sponge-like porous metals (nickel, iron, copper) and their composite porous structures serve as filtration carriers, chemical catalyst supports, electromagnetic shielding materials, and precious metal replacement/recovery agents across diverse fields.

2. Nickel foam primarily functions as battery electrode material, particularly in NiMH batteries. These rechargeable batteries are widely used in laptops, mobile phones, electric scooters, e-bikes, and hybrid vehicles.

3. Nickel foam serves as an electrocatalyst for molten carbonate fuel cells (MCFCs), typically operating at 550-700°C. It functions as a modifier for electrode plates in proton exchange membrane fuel cells (PEMFCs), an electrode relay conductor in solid oxide fuel cells (SOFCs), and an electrode material in electrolysis (e.g., water electrolysis). Increasing surface area also facilitates hydrogen and syngas production for fuel cells.

4. Unique open-cell structure, low-pressure access pores, inherent tensile strength, and thermal shock resistance make nickel foam a potential catalyst support for automotive catalytic converters, catalytic combustion systems, and diesel particulate filters. During engine cold starts, the conversion of carbon monoxide and hydrocarbons may benefit from foam nickel catalyst supports over ceramic carriers due to thermal conductivity properties. In this regard, foam nickel may be comparable to or superior than high-temperature steel catalyst supports. Other applications for nickel foam catalysts include Fischer-Tropsch reactions, gas modification, and hydrogenation reactions for fine chemicals using foam catalyst carriers.

5. Nickel foam can serve as a filter material and magnetic flux conductor for treating magnetic particles in fluids. Additional applications include hydrogen storage media and heat exchange media.

The nickel foam industry is currently operating under favorable development conditions, with enterprises progressively advancing toward industrialization and large-scale production. Foam nickel is an excellent sound-absorbing material exhibiting high sound absorption coefficients at high frequencies; its low-frequency sound absorption performance can be enhanced through structural design.

Through experimentation, a process for preparing foamed nickel using electrodeposition technology has been successfully developed. The substrate material used is porous open-cell foam plastic. Conductive layers can be prepared using three methods: electroless nickel plating, vacuum nickel plating, and immersion in conductive adhesive. After pre-nickel plating, thick nickel can be electroplated in a common sulfate nickel plating electrolyte. followed by calcination, reduction, and annealing processes to yield high-performance foamed nickel materials.
