Nickel foam can be used as a filter material, a magnetic flow conductor for dealing with magnetic particles in fluids. Other applications include application to hydrogen storage predicates and heat exchange predicates. Nickel foam is a sound-absorbing material with excellent performance, which has a high sound-absorbing coefficient at high frequencies; its sound-absorbing performance at low frequencies can be achieved through the design of the sound-absorbing structure. Nickel foam is also one of the good electrode materials for making cadmium-nickel batteries and hydrogen-nickel batteries. The process of preparing nickel foam by electro-deposition technique was successfully developed through experiments. The base material used is porous open-cell foam plastic. The conductive layer can be prepared by three methods: chemical nickel plating, vacuum nickel plating and immersion conductive adhesive. After pre-nicking, it can be plated in a common sulfate nickel plating solution. Nickel, after burning, recovery and annealing process, can obtain nickel foam material with excellent performance.
