Nickel fibre felt electrodes are emerging as a game-changer in energy storage and catalysis, thanks to their unique 3D porous structure, high electrical conductivity (≥10⁴ S/m), and exceptional thermal stability. At Beihai Composite, we’ve pioneered a scalable manufacturing process that ensures precision and performance for next-gen applications.

Key Features & Manufacturing Innovations

1.Fibre Synthesis: Using patented electrospinning technology, ultra-fine nickel fibres (diameter 1–10 μm) are woven into a felt-like matrix, achieving tunable porosity (70–95%) for optimal ion/electron transport.

2.Sintering Process: A controlled vacuum sintering step at 800–1,200°C enhances mechanical strength while preserving the interconnected pore network critical for high-surface-area reactions.

3.Surface Functionalization: Optional coatings (e.g., Pt, RuO₂) can be applied via chemical vapor deposition to tailor electrodes for hydrogen evolution, supercapacitors, or fuel cells.

Performance Advantages

  • Energy Efficiency: Reduces charge transfer resistance by 40% compared to traditional foam electrodes.
  • Durability: Maintains structural integrity after 10,000+ charge cycles in lithium-sulfur battery tests.
  • Customization: Available in thicknesses (0.5–10 mm) and pore densities (10–200 PPI) to meet specific application needs.

Applications Driving Industry Transformation

  • Batteries: Enhances energy density in Li-ion and solid-state batteries.
  • Fuel Cells: Improves catalyst utilization in PEM and alkaline fuel cells.
  • Electrolysis: Boosts hydrogen production efficiency in water-splitting systems.
