Introduction:

Nickel foam is a sound-absorbing material with excellent performance, which has a high sound-absorption coefficient at high frequencies; its sound-absorbing performance at low frequencies can be improved through the design of the sound-absorbing structure. Nickel foam is also one of the best electrode materials for making cadmium-nickel batteries and hydrogen-nickel batteries. Nickel foam is a sound-absorbing material with excellent performance, which has a high sound absorption coefficient at high frequencies; the sound absorption performance at low frequencies can be improved through the design of the sound-absorbing structure.

Production Process:

The process of preparing foamed nickel by electrodeposition technology has been successfully developed through experiments. The substrate material used is porous open-cell foam plastic, and the conductive layer can be prepared by three methods: electroless nickel plating, vacuum nickel plating, and dipping conductive glue (palladium sol, submicron graphite emulsion, etc.), and can be pre-plated. Thick nickel is electroplated in the general sulfate nickel plating electrolyte, and then the three-dimensional network foam nickel material with excellent performance can be obtained after burning, reducing and annealing processes.

Application:

1. Battery electrode materials
Nickel foam is mainly used for battery electrode materials, especially for NiMH batteries, which are widely used in laptop computers, mobile phones, electric scooters, electric bicycles, and hybrid vehicles.
2. Fuel cells
The usual operating temperature of molten carbonate fuel cells is between 550-700°C, and nickel foam can be used as an electrocatalyst for molten carbonate fuel cells.
3. Catalyst material
The unique opening structure, low-pressure input hole, inherent tensile strength and thermal shock resistance make nickel foam a catalyst carrier for automotive catalytic converters, catalytic combustion, and black smoke purifiers for diesel vehicles.
4. Other
Nickel foam can be used as a filter material, a magnetic current conductor for magnetic particles in fluids. Other applications include applications in hydrogen storage media, heat exchange media.
