Nickel foam is an excellent acoustic material with high sound absorption coefficient at high frequencies; its sound absorption performance at low frequencies can be improved by the design of acoustic structure. Nickel foam is also one of the better electrode materials for manufacturing cadmium-nickel batteries and hydrogen-nickel batteries. Nickel foam is mainly used as electrode material for batteries, especially for NiMH batteries, which are widely used in laptop computers, cell phones, electric scooters, electric bicycles and hybrid cars.

Nickel foam is used as a filter material, a magnetic flow conductor for handling magnetic particles in fluids. Other applications include the application of hydrogen storage media, heat exchange media. Nickel foam is an excellent sound-absorbing material with high sound absorption coefficient at high frequencies; its sound absorption performance at low frequencies can be improved through the design of the sound-absorbing structure.
Nickel foam is also one of the better electrode materials for manufacturing cadmium-nickel and hydrogen-nickel batteries. The process of preparing nickel foam by electrodeposition technology was successfully developed through experiments. The substrate material used is porous open-cell foam, using chemical nickel plating, vacuum nickel plating and dipping conductive gel three methods can be prepared conductive layer, by pre-plating nickel can be plated in a common nickel sulfate plating electrolyte thick nickel, after burning, reduction. After burning, reduction, annealing process can be obtained excellent performance of nickel foam materials
