Copper foam with good ductility and low cost
Aug 22, 2018

Copper foam can be used as a heat sink materials, heat-absorbing material, chemical catalyst support, electromagnetic shielding materials, filtration, damping material, battery electrode materials, noise, high grade decorative material.

Many people want to know what is the difference between copper foam and nickel foam as a battery current collector.

Copper foam is a new type of multifunctional material with a large number of connected or non-connected pores evenly distributed in a copper matrix. The copper foam has good electrical conductivity and ductility, and has a lower preparation cost than the foamed nickel, and has better electrical conductivity, and can be used for preparing a battery negative electrode (carrier) material, a catalyst carrier, and an electromagnetic shielding material. In particular, the use of copper foam as a base material for batteries as electrodes has some obvious advantages, but its corrosion resistance is not as good as that of nickel, which limits its application.

Nickel foam is an excellent sound absorbing material with high sound absorption coefficient at high frequencies; its sound absorption structure can improve its sound absorption performance at low frequencies.
