II. Main Features

Copper foam has excellent thermal conductivity and can be used for heat conduction and dissipation in motors, electrical appliances and electronic components.
Due to its superior electrical conductivity, copper foam is gaining industry attention for applications as electrode materials in nickel-zinc batteries and electric double-layer capacitors.
Thanks to its structural characteristics and human-friendly properties, copper foam is also an excellent medical filtration material and water purification filter medium.

III. Application Areas

Electrode Materials: The excellent electrical conductivity allows copper foam to be applied as skeletal electrode material for new-type batteries such as nickel-zinc batteries and electric double-layer capacitors. It has been trialed and put into batch use by several nickel-zinc battery manufacturers. It is also expected to be promoted as a current collector for electric double-layer capacitor electrodes. Moreover, copper foam used as an electrode material for electrolytic recovery of copper-containing wastewater shows very broad prospects.
Catalysts: In many organic chemical reactions, people attempt to directly use copper foam with large specific surface area to replace punched copper plates as chemical reaction catalysts. Copper foam as a carrier for photocatalytic air purification has also been successfully applied.
Thermal Conduction Materials: Copper foam has excellent thermal conductivity, making it a superior flame-retardant material applied in many advanced fire-fighting equipment overseas, especially as a flame isolation device with outstanding effects. Additionally, using its excellent thermal conductivity and apparent permeability, copper foam is made into heat dissipation materials for motors and electrical appliances.
Sound Absorption and Shielding Materials: Sound waves undergo diffuse reflection on the surface of copper foam, achieving noise reduction through expansion silencing and micro-pore sound absorption principles. The shielding performance of copper is close to silver, making it an excellent electromagnetic shielding material.
Filter Materials: With excellent structural characteristics and human-friendly properties, copper foam metal products have been successfully applied as filter materials. Copper foam also shows good prospects in water purification device applications.
Fluid Pressure Buffering Materials: The dispersion and buffering effect of copper foam on fluids makes it an effective pressure reduction protection device for various pressure instruments.

What is the typical trade-off between pore size and porosity in copper foam for heat dissipation applications?

Copper foam pore size ranges from 0.1 mm to 10 mm (5–120 ppi) and porosity from 50% to 98%, with a 99% open rate and ≥98% through-hole rate. For heat dissipation, higher porosity increases surface area for convective heat transfer but reduces the continuous solid copper path, lowering effective thermal conductivity. The optimal balance depends on the specific cooling requirement, as the material is designed for use in motors, electronics, and LED heat sinks.

Can copper foam be directly integrated as an electrode material in nickel-zinc batteries without additional surface treatment?

Yes, copper foam has been trialed and put into batch use by several nickel-zinc battery manufacturers as a skeletal electrode material. Its excellent electrical conductivity and three-dimensional porous structure enable direct use without additional treatment. The source also notes it is expected to be promoted as a current collector for electric double-layer capacitor electrodes.

How does the radial breaking strength of 0.2 N/cm affect handling and shaping of the copper foam?

The radial breaking strength of 0.2 N/cm, combined with filament diameters of 0.01–10 mm, indicates the foam is mechanically delicate and requires careful handling during cutting, bending, or shaping to avoid tearing. Despite this, the source states the material has good tensile strength and ductility, suggesting moderate flexibility under controlled conditions.

Assessment

Copper foam sheet (100x180x3mm) with 99% open rate and ≥98% through-hole rate provides high permeability and thermal/electrical conductivity, suited for filtration, heat dissipation, and electrode applications, though its low radial breaking strength (0.2 N/cm) and variable porosity require careful handling and performance validation.

Positive

High open rate and through-hole rate: 99% open rate and ≥98% through-hole rate enable efficient fluid flow and filtration with minimal pressure drop, supporting applications in dry filtration and water purification.
Excellent thermal and electrical conductivity: Copper's inherent conductivity supports heat dissipation in motors and electronics, and enables use as electrode material in nickel-zinc batteries and electric double-layer capacitors.

Trade-offs

Low radial breaking strength: Radial breaking strength of 0.2 N/cm indicates limited mechanical integrity, requiring careful handling and support in load-bearing applications to prevent deformation or fracture.
Variable porosity and bulk density: Porosity ranges 50-98% and bulk density 0.1-0.8 g/cm³, meaning the specific sheet's properties may vary, affecting performance predictability and requiring validation for target applications.
