Product Overview
|
| This next-generation Nickel Foam is engineered as a sponge-like porous metal material featuring a 45 PPI knitted 3D reticulated architecture manufactured through a specialized deposition process. With a specific gravity of merely 0.2–0.3—approximately one-quarter that of water and one-thirtieth that of iron—the hollow interconnected nickel skeleton achieves a bulk density of only 1/50th that of solid nickel while preserving the full spectrum of nickel’s intrinsic physicochemical properties. The fully open-cell structure delivers an exceptionally high specific surface area, making it an optimal fuel cell electrode substrate for Ni-H₂, Ni-Cd, and proton exchange membrane systems, as well as a nickel foam-carbon composite electrode platform for advanced lithium-ion energy storage. Exhibiting broadband acoustic absorption, high thermal conductivity, and robust acid-alkali corrosion resistant performance, this knitted metallic foam supports stable gas-liquid mass transfer and can be readily cut, bent, and bonded for integration into complex electrochemical, catalytic, and thermal management assemblies. |

Key Features & Advantages
|
- Ultra-Lightweight Hollow Skeleton Architecture: The knitted nickel skeleton achieves a specific gravity of 0.2–0.3 with bulk density merely 1/50th that of solid nickel. The hollow interconnected strut morphology maximizes specific surface area while minimizing mass, delivering an exceptional strength-to-weight ratio for portable energy storage and aerospace functional material applications.
- Sponge-Like 3D Fully Interconnected Porosity: The specialized deposition process creates a true sponge-like reticulated structure with 100% open-cell connectivity, ensuring stable gas-liquid mass transfer and uniform fluid distribution across the entire substrate volume—critical for electrochemical reactions and catalytic processes where dead zones compromise efficiency.
- Broadband Acoustic Absorption Capability: The stochastic 45 PPI knitted pore network effectively dissipates acoustic energy across a wide frequency spectrum through viscous friction and thermal conduction mechanisms within the micro-pores, enabling simultaneous noise reduction and structural functionality in integrated multifunctional designs.
- Versatile Post-Processing Compatibility: The ductile nickel substrate can be readily cut, bent, and bonded without fracturing the interconnected strut network, facilitating custom shaping into complex geometries for application-specific electrochemical reactor, heat exchanger, and EMI shielding enclosure configurations.

APPLICATION SCOPE: Validated as a high-performance electrode substrate in Ni-H₂, Ni-Cd, and fuel cell systems, with nickel foam-carbon composite configurations optimized for lithium-ion batteries deployed in consumer electronics, electric vehicles, and power tools. Functions as a catalyst carrier and oil-water/oil-gas separation medium in chemical engineering processes, including automotive exhaust purification and air purification systems. Supports electrolytic hydrogen production, electrocatalysis, and electrochemical metallurgy in energy engineering applications. Serves as a thermal management material and heat pipe wick core for enhanced heat exchange efficiency. Applicable as a multifunctional material for acoustic absorption, vibration damping, electromagnetic shielding, stealth technology, flame retardancy, and thermal insulation in defense and industrial sectors.
PACKAGING: Supplied in custom-cut sheet configurations within the dimensional range of 70 mm to 500 mm for both length and width (±0.5 mm tolerance). Thickness is selectable from 0.5 mm to 80 mm (±0.05–1.0 mm tolerance). Standard areal density ranges from 280 to 3000 g/m² (±30–200 g/m²). Pore density is available from 5 to 130 PPI (±5–10 PPI), with 45 PPI as the standard offering. Each sheet is vacuum-sealed in low-outgassing polyethylene film with rigid protective backing to preserve the delicate knitted 3D reticulated structure during transit. Custom dimensions and PPI specifications manufactured to order.
IMPORTANT NOTICE: When handling knitted nickel foam sheets with thickness below 1 mm, utilize vacuum pickup tools or flat-tipped tweezers to avoid localized plastic deformation of the hollow strut network. For electrochemical electrode applications, pre-conditioning of the nickel surface via cyclic voltammetry in the target electrolyte is recommended to establish a stable electrochemical interface prior to active material loading. The material retains nickel’s intrinsic hydrogen absorption characteristics—hydrogen uptake increases with decreasing strut diameter—necessitating appropriate safety protocols during hydrogen-rich electrochemical operations. While the nickel skeleton is inherently acid-alkali resistant, prolonged exposure to oxidizing acids at elevated temperatures may gradually dissolve the passivating surface oxide layer. For maximum shelf stability, store in a desiccated, temperature-controlled environment.
