• High Пористость (50-85%): It is mostly empty space, allowing fluids and gases to flow through it with relatively low resistance.

• Very High Surface Area to Volume Ratio: The tangled web of fine fibers provides an enormous surface area within a small volume.

• Excellent Electrical Conductivity: Being made of metal, it conducts electricity very well in all dimensions.

• Good Thermal Conductivity: Efficient at transferring heat.

• Permeability: Allows for controlled flow of gases and liquids.

• Mechanical Robustness: The sintered structure provides good strength and rigidity compared to polymer-based felts, allowing it to be handled and assembled into devices.

• Malleability: It can be easily cut, punched, and shaped to fit into various geometries (e.g., electrodes for fuel cells or batteries).

• Химическая Resistance: Nickel offers good resistance to corrosion and oxidation, especially in alkaline environments.

• Battery Industry:
  • Used as a negative electrode current collector in lithium-ion batteries (especially high-energy-density types) and solid-state batteries—improves electron transfer and accommodates electrode volume changes.
  • Cathode substrate for nickel-metal hydride (Ni-MH) batteries.
• Catalysis & Химическая Engineering:
  • High-surface-area carrier for catalysts (e.g., hydrogenation, oxidation reactions in petrochemicals).
  • Support for fuel cell electrodes (e.g., proton exchange membrane fuel cells, PEMFCs) to enhance gas diffusion and reaction efficiency.
• Filtration:
  • High-temperature gas/liquid filtration (e.g., filtering impurities in molten metals, exhaust gases from high-heat processes) due to its heat and corrosion resistance.
• Electronics & Energy:
  • Electromagnetic shielding components (leveraging nickel’s conductivity).
  • Heat dissipation pads (combines porosity for airflow and metal conductivity for heat transfer).
• аэрокосмическая & Metallurgy:
  • Thermal insulation in high-temperature environments (e.g., rocket engines) and as a diffusion barrier in metal processing.
