Nickel Foam Application

Spongy porous metal nickel, iron, copper and their composite layer porous bodies can be used as filter carriers, chemical catalyst carriers, electromagnetic shielding materials, precious metal replacement and recovery and many other fields.

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 working temperature of molten carbonate fuel cells is usually between 550-700 °C, and nickel foam can be used as an electrocatalyst for molten carbonate fuel cells. Nickel foam can be used as a bipolar plate modification material for proton exchange membrane production cells (PEMFC), electrode relay feeders for solid oxide fuel cells (SOFC), and electrode materials in electrolysis (such as in water electrolyte environments). The increased surface area can also be used to generate hydrogen and syngas for fuel cells.

3. Catalyst material

The unique open-cell structure, low-pressure input hole, inherent tensile strength and thermal shock resistance make nickel foam a possible catalyst carrier for automotive catalyst converters, catalytic combustion, and diesel vehicle black smoke purifiers. When the engine is cold started, carbon monoxide and hydrocarbons are converted. Due to the heat conduction properties, the foamed nickel catalyst carrier may be superior to the ceramic catalyst carrier. In this sense, the nickel foam can be compared with the high temperature resistant steel catalyst carrier. Steel catalyst supports are more superior. Other applications for nickel foam catalysts can include Fischer-Topsch reactions, gas modification, hydrogenation of fine chemicals, and foam catalyst supports.

4. Other applications

Nickel foam can be used as a filter material, a magnetic flow conductor that handles magnetic particles in fluids. Other applications include applications in hydrogen storage media, heat exchange media. my country's nickel foam industry is in good operation and development, and enterprises in this industry are gradually developing towards industrialization and large-scale development. 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. Nickel foam is also one of the best electrode materials for the manufacture of cadmium-nickel batteries and hydrogen-nickel batteries. The process of preparing nickel foam by electrodeposition technology has been 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. Nickel, after burning, reduction, annealing process can get excellent performance of nickel foam material.
