Reticulated Metal Foam 30–140 PPI 98% Open-Cell ATOMFAIR®

RETICULATED METAL FOAM 30-140 PPI 98% THROUGH-POROSITY ELECTRODE SUBSTRATE

RESEARCH GRADE MATERIAL

Product Overview

Engineered for advanced electrochemical and thermo-fluidic research, this Reticulated Metal Foam serves as a high-performance conductive porous media with exceptional structural homogeneity. The substrate achieves a 98% through-porosity 30-140 PPI rating, eliminating closed-cell barriers to ensure unimpeded fluid and gas permeation for filtration studies. The interconnected three-dimensional network provides a significantly enhanced specific surface area, making it an optimal electrode current collector substrate for next-generation Ni-Zn batteries and supercapacitors. With a precisely controlled pore density range spanning 30–140 PPI, pore sizes from 0.3 mm to 7 mm, bulk density of 0.1–2.0 g/cm³, and areal density of 100–2000 g/m², this foam facilitates uniform current distribution and catalytic loading. The surface is passivated against atmospheric oxidation and the product is vacuum-sealed passivated surface packaged between rigid protective plates, delivering reproducible results in demanding research and development environments.

Key Features & Advantages

Maximized Electrochemical Surface Area: The 3D reticulated structure provides a significantly larger specific surface area compared to flat substrates or traditional meshes, enhancing charge transfer kinetics in cyclic voltammetry and galvanostatic cycling measurements.
True Open-Cell Permeability: Guaranteeing ≥98% through-porosity, this conductive porous media eliminates stagnation zones, ensuring uniform fluid flow and mass transport in flow batteries and catalytic filtration reactors.
Broad-Frequency Acoustic Attenuation: The stochastic micro-pore geometry effectively traps and dissipates acoustic energy via viscous friction, providing superior noise reduction for high-frequency electronic component enclosures.
Hybrid Thermal-Mechanical Performance: Exhibiting excellent electrical conductivity alongside flame-arresting properties, the foam serves as a dual-purpose heat spreader and fire-retardant barrier for battery pack safety applications.

APPLICATION SCOPE: Validated for use as an electrode skeleton in Ni-Zn batteries and electric double-layer capacitors. Compatible as a high-surface-area catalyst carrier in fixed-bed reactors and as an electromagnetic interference shielding core in sensitive analytical instrumentation. Suitable for inert atmosphere liquid filtration and dynamic pressure dampening in relief valves.

PACKAGING: Supplied as a single monolithic sheet (500 × 500 mm). The surface is passivated against atmospheric oxidation. The product is vacuum-sealed within a low-outgassing polyethylene bag and placed between rigid protective plates to prevent mechanical deformation of the delicate micro-porous structure during transit.

IMPORTANT NOTICE: For extreme high-temperature electrochemical applications (T > 300°C), pre-treatment of the metal foam in a reducing atmosphere is recommended to remove surface oxides. To preserve the 98% through-hole structural integrity, manual handling must utilize vacuum pickup tools; lateral mechanical gripping may collapse edge pores. Store in a desiccator or glovebox immediately after unsealing to prevent moisture adsorption.

The reticulated metal foam surface is passivated to resist atmospheric oxidation and is vacuum-sealed to maintain integrity during transport. To preserve the 98% through-hole structure, handle only with vacuum pickup tools and store in a desiccator or glovebox immediately after unsealing.

High-temperature pre-treatment: For applications above 300°C, pre-treat the foam in a reducing atmosphere to remove surface oxides.
Handling requirement: Use vacuum pickup tools to avoid collapsing edge pores during manual handling.
Storage requirement: Store the unsealed foam in a desiccator or glovebox immediately to prevent moisture adsorption.
Packaging protection: The foam is vacuum-sealed between rigid protective plates to prevent mechanical deformation during transit.
Surface passivation: The passivated surface protects against atmospheric oxidation during storage and handling.

FAQ

What are the key specifications of the reticulated metal foam that make it suitable as an electrode substrate?

The foam features a 98% through-porosity with a pore density of 30–140 PPI, pore sizes from 0.3 mm to 7 mm, and a bulk density of 0.1–2.0 g/cm³. Its interconnected 3D network provides a significantly enhanced specific surface area, ensuring uniform current distribution and catalytic loading for electrode applications.

Can this metal foam be used in Ni-Zn batteries and supercapacitors?

Yes, it is validated for use as an electrode skeleton in Ni-Zn batteries and electric double-layer capacitors. The high through-porosity and specific surface area enhance charge transfer kinetics, making it suitable for cyclic voltammetry and galvanostatic cycling measurements.

What special handling and storage conditions are required for the reticulated metal foam?

The foam is vacuum-sealed and passivated against oxidation; after unsealing, store it in a desiccator or glovebox to prevent moisture adsorption. Manual handling must use vacuum pickup tools; lateral mechanical gripping may collapse edge pores, and for high-temperature applications above 300°C, pre-treatment in a reducing atmosphere is recommended.

Assessment
