Product Features

Foam copper is a new type of multifunctional material with a large number of connected or disconnected pores evenly distributed in the copper matrix. Foam copper is widely considered as the third generation anode collector of lithium batteries. In addition to its high energy density, it can effectively inhibit the shrinkage and expansion of lithium ions during charging and discharging, and effectively improve battery safety.

Applications:

(1) Electrode materials. Excellent conductivity makes copper foam can be widely used in nickel-zinc batteries, electric double-layer capacitors and other new battery electrode skeleton materials, copper foam has been tried by a number of nickel-zinc battery manufacturers, and put into batch use, at the same time, copper foam is expected to be used as an electric double-layer capacitor electrode current collector to be popularized and applied; In addition, copper foam can be used as an electrode material for the electrolytic recovery of copper-containing wastewater.

(2) Catalyst. In many organic chemical reactions, people try to directly use copper foam with large specific surface area to replace perforated copper plates as chemical reaction catalysts. As a photocatalytic air purification carrier, copper foam has also been successfully applied.

(3) Thermally conductive materials. Copper foam has excellent thermal conductivity, making it a flame retardant material with excellent performance, and has been applied in many advanced foreign fire-fighting equipment, especially as a flame isolation equipment with excellent results; In addition, people use the excellent thermal conductivity and apparent permeability of copper foam to make heat dissipation materials for motors and electrical appliances.

(4) Silencing and shielding materials. The sound wave is diffusely reflected on the surface of the copper foam, and the effect of noise reduction is achieved through the principles of expansion and microporous sound reduction. The shielding performance of copper is close to that of silver, and it is an electromagnetic shielding material with excellent performance.

(5) Filter material. Copper foam metal products, which have excellent structural characteristics and are basically harmless to the human body, have also been successfully applied as medical filter materials; At the same time, the application of copper foam in water purification devices also has a good future.

(6) Fluid pressure buffer material. The dispersion and buffering effect of copper foam on fluids makes it an excellent decompression protection device for various pressure instruments.
