How does the 90PPI pore structure and 60% porosity of this copper foam influence its performance in battery electrodes and sound absorption?

The 90PPI (pores per inch) rating corresponds to a pore size of 0.1 mm, with a through-hole rate of ≥98%, ensuring an open, interconnected network. This structure provides a high specific surface area for electrochemical reactions in battery electrodes and enhances sound absorption via micro-pore dissipation and diffuse reflection. The 60% porosity and areal density of 0.42 g/cm³ balance mechanical strength with active material loading, making it suitable for both structural and functional applications.

Can this copper foam be used as a current collector for electric double-layer capacitors?

Yes. The product description explicitly states that copper foam has been trialed and put into batch use by several manufacturers as a current collector for electric double-layer capacitor electrodes, and it is expected to be promoted for this application. Its superior electrical conductivity and open-cell structure are cited as the key enablers, along with its suitability for electrolytic recovery of copper-containing wastewater.

Are custom dimensions available for this copper foam, and what is the standard sheet size?

The standard sheet dimensions are 200 mm × 300 mm × 2 mm, but the product description explicitly states that sizes can be customized. For any customization requests, contacting the engineering team at inquiry@atomfair.com is provided as the direct channel. This flexibility allows adaptation to specific electrode, filtration, or shielding designs.

Assessment

This copper foam sheet (90 PPI, 60% porosity, ≥98% through-hole rate) offers a unique combination of thermal and electrical conductivity for battery electrode current collectors and heat dissipation, with sound absorption and EMI shielding capabilities. The fixed 200×300×2mm dimensions and 0.42 g/cm³ areal density provide a specific form factor suitable for laboratory prototyping and small-scale applications.

Positive

High thermal and electrical conductivity: The copper foam exhibits excellent thermal conductivity for heat dissipation in motors and electronics, and superior electrical conductivity making it suitable as a skeletal electrode material for nickel-zinc batteries and electric double-layer capacitors.
Multifunctional porous structure: With 90 PPI, 60% porosity, and ≥98% through-hole rate, the open-cell honeycomb structure enables sound absorption via diffuse reflection and micro-pore silencing, as well as EMI shielding performance close to silver.

Trade-offs

Fixed dimensions and density: The product is supplied at 200×300×2mm with an areal density of 0.42 g/cm³, which may require custom sizing for specific application geometries or scaling.
Moderate porosity level: At 60% porosity, the void fraction is lower than typical high-porosity foams (e.g., 90%+), which limits the available surface area for catalytic reactions or electrode loading in some applications.
