Sintered Fiber Felt
Nickel Fiber Felts is made of micron-level pure nickel fiber in accordance with foreign technical standards, through special felt laying process and ultra-high temperature vacuum sintering process.
Compared with nickel mesh or nickel powder sintered plate, nickel fiber felt has excellent three-dimensional network porous structure, high porosity, large specific surface area, uniform pore size distribution, strong corrosion resistance, good water permeability, good heat dissipation and stable performance, long life and other advantages.
Comparison of the properties between Ni fiber felt and nickel foam:
| Property | Ni fiber felt | Nickel Foam |
| Thickness /mm | 0.25-2.0 | 0.5-3.0 |
| Porosity /% | 40-90% | 50-130PPI |
| Unit weight /g m² | 300-1000 | 350-1000 |
| Pore size /u m | 3-100 | 50-5000 |
| Specific surface area /cm²cm³ | (0.5-2.0)X 10⁵ | 50 |
| Tensile strength /MPa | 5-8 | 0.1-1.5 |
| Elongation /% | ≥8 | ≥5-7 |
In conclusion
1) The thickness, pore size, unit weight, porosity and other performance indicators of nickel fiber felt can be comparable to nickel foam.
2) Nickel fiber felt has the characteristics of larger specific surface area, higher tensile strength and better flexibility than foamed nickel, and is suitable for making large-capacity, high-current nickel-metal hydride batteries.
