Laboratory Open-Cell Nickel Foam, 20 PPI, 200 × 200 × 20 mm, 1/5 pcs
Research-grade laboratory product
Product Overview

Open-cell nickel foam with 20 PPI is a lightweight, electrically conductive porous-metal sheet built around a continuous three-dimensional nickel skeleton. In this 200 × 200 × 20 mm format, the approximately 1.27 mm nominal pore pitch creates a regular open network with extensive internal surface exposure, allowing gases, liquids and electrochemical reactants to move through the material instead of remaining confined to the outer faces.

The interconnected framework gives the sheet a useful balance of permeability, formability and structural continuity. It can be cut, bent or bonded into laboratory assemblies while preserving the open pathways needed for filtration, catalytic contact, electrode loading and heat transfer. The nickel matrix also makes the foam relevant where electrical conduction, thermal response, corrosion resistance, acoustic attenuation or electromagnetic shielding must be combined with a low-mass cellular structure.

This specification is suitable for evaluating battery and fuel-cell electrodes, nickel-carbon composite electrode structures, catalyst carriers, exhaust and air-purification media, oil-water separation, industrial filtration, hydrogen electrolysis, electrocatalysis, heat-pipe wicks, condenser structures and distillation packing. Select the PPI, sheet dimensions and thickness around the intended flow, surface-area and integration requirements; choose a 1-piece pack for initial evaluation or a 5-piece pack for repeated trials and small-batch assembly.

Application areas include nickel-metal-hydride, nickel-cadmium and fuel-cell positive and negative electrodes; nickel-carbon composite electrodes for lithium batteries; catalyst and exhaust-purification carriers; air purification, oil-water separation and industrial filtration; hydrogen electrolysis, electrocatalysis and electrochemical metallurgy; infrared-burner surfaces and industrial or domestic drying-heater structures; heat-pipe wicks and condenser heat-transfer media; distillation-tower packing; and functional damping, acoustic, vibration-buffering, electromagnetic-shielding, thermal-insulation and decorative structures.
SELECTION GUIDANCE: Confirm PPI, nominal pore pitch, porosity requirement, through-pore rate, sheet length and width, thickness, bulk-density range, operating environment and required quantity before quotation. Confirm application-critical corrosion, temperature, mechanical and integration requirements before ordering.
HANDLING & INSPECTION: Store the sheets in a clean, dry area and protect the open cellular surface from heavy impact, crushing and contamination. After delivery, check the package condition, sheet dimensions and visible pore structure before cutting, bonding or installing the material.
IMPORTANT NOTICE: Custom dimensions are available upon consultation. For a dimensional feasibility review by e-mail, provide the target length, width, thickness, PPI and estimated quantity.

  • Storage Environment: Store the sheet in a clean, dry area with minimal dust and moisture exposure.
  • Mechanical Protection: Protect the open cellular surface from heavy impact, crushing, and contamination during handling and storage.

How does the 20 PPI pore density affect the balance between permeability and mechanical strength for electrode applications?

The 20 PPI structure with approximately 1.27 mm nominal pore pitch provides a balance of permeability and structural continuity. The foam has a tensile strength of 8–50 MPa and compressive strength ≥250 kPa, with porosity 60–98% and through-pore rate ≥98%. This combination supports gas/liquid flow while maintaining mechanical integrity for electrode loading.

Is this nickel foam compatible with alkaline battery electrolytes and high-temperature hydrogen electrolysis conditions?

Yes, the nickel matrix offers resistance to acid/alkali conditions and listed temperature resistance ≥500°C with high-temperature capability >1100°C. The open-cell structure with ≥98% through-pore rate is suitable for hydrogen electrolysis and electrocatalysis applications as stated in the application scope.

What are the recommended methods for cutting and bonding this 20 mm thick nickel foam without damaging the pore structure?

The foam can be cut, bent, and bonded for downstream fabrication. The source advises protecting the open cellular surface from heavy impact, crushing, and contamination during handling. Specific cutting methods are not detailed, but the material's formability allows standard sheet metal cutting tools; bonding should preserve open pathways.

Open-cell nickel foam sheet with 20 PPI pore density provides a high-porosity, electrically conductive, and thermally stable porous metal network suitable for electrochemical electrodes, catalyst supports, and filtration media, but requires careful handling due to limited mechanical strength.

Positive

  • High through-pore rate and porosity: With ≥98% through-pore rate and 60–98% porosity, the material ensures excellent fluid permeability and electrochemical reactant accessibility, critical for electrode and filtration applications.
  • Combined thermal and electrical conductivity with high-temperature stability: The nickel matrix provides electrical conduction, a heat-transfer coefficient >3 W/(m²·K), and temperature resistance ≥500°C (up to >1100°C), enabling use in catalytic and electrochemical environments.

Trade-offs

  • Low mechanical strength: Tensile strength ranges from 8 to 50 MPa and compressive strength is only ≥250 kPa, making the foam vulnerable to deformation or damage under mechanical load or impact during handling and integration.
  • Low bulk density and specific gravity: With bulk density of 0.1–0.8 g/cm³ and specific gravity of 0.2–0.3, the material has low mass per volume, which may limit structural rigidity in high-pressure or high-flow setups.
