nickel foam

Nickel foam is a new type of porous metallic material with a wide range of applications, and its characteristics include lower density and higher specific surface area.
Nickel foam is mainly made of nickel material with a porous structure, which is formed by controlling the particle size of the nickel powder and adding a control agent, sintering into spherical particles under high temperature conditions, and then expanding the spherical particles under high temperature and high pressure hydrogen The spherical particles are then expanded under high temperature and high pressure hydrogen atmosphere.
These properties in the preparation of nickel foam make it widely used in catalysts, batteries, filters and other fields. Nickel foam not only has good electrical conductivity and chemical/electrochemical stability, but also has catalytic activity, lightweight, flame retardant, breathable, acoustic and electromagnetic wave absorbing properties, which makes it an ideal choice as an electrode collector material for nickel-based secondary batteries and supercapacitors.
In addition, nickel foam is also used in new chemical power sources such as fuel cells/metal air batteries/lithium-ion batteries, electrochemical engineering fields such as electrochemical water treatment, electrochemical synthesis, electrochemical sensors, and chemical engineering fields such as catalytic/separation filtration/heat exchange.It also shows good application prospects in chemical fields such as catalysis/separation and filtration/heat exchange.

Due to its unique three-dimensional network structure and excellent performance, nickel foam also plays an important role in wave absorption, filtration, catalysis, energy storage and other fields.
