Introduction of foam copper

Copper foam is a new type of multi-functional material. It mainly uses copper as the substrate, and a large number of connected or disconnected holes are evenly distributed in it, thus producing a new type of multi-functional material of copper foam.

Copper foam has good electrical conductivity and ductility, and the preparation cost is lower than that of nickel foam, and the electrical conductivity is good, and can be used for the preparation of battery negative electrode (carrier) material, catalyst carrier and electromagnetic shielding material. In particular, as the matrix material of battery electrodes, copper foam has some obvious advantages, but the corrosion resistance of copper is not as good as that of nickel, which limits its application in some fields.

Pure copper is a soft metal, the surface is orange-red when it is just cut, and the element is purple-red. It has good toughness and high thermal conductivity, so it is the most commonly used material in cables, electrical appliances and electronic components. It can also be used as a building material and can be composed of various alloys.
