Detalles

This nickel foam, with a thickness of 2.0 mm, is developed as a high-porosity current collector and electrode substrate for energy storage and conversion devices. Featuring a three-dimensional network structure, it combines ultra-lightweight properties (specific gravity 0.2–0.3) with excellent electrical conductivity and thermal stability, making it suitable for supercapacitors, fuel cells, and catalyst support applications. The material demonstrates wide-frequency sound absorption, approximately 90 dB electromagnetic shielding, and resistance to temperatures over 1100 °C along with corrosion resistance in acidic and alkaline electrolytes. Its open-cell design facilitates efficient gas and fluid flow, while the foam can be easily cut, bent, or adhered for customized electrode fabrication. Available in various sheet and disc sizes, this product supports precise coating density calculations for active material loading and is fully recyclable.

1. Coating surface density does not include current collector material.

2. Theoretical areal capacity (mAh/cm2) = Coating surface density (mg/cm2) * Active material ratio * Specific capacity (mAh/g) ÷ 1000.

3. Theoretical mass of active material (mg) = Coating surface density (mg/cm2) * Active material ratio * Area of the electrode (cm2).

4. Actual weight-based calculation of active material (mg) = (Weight of electrode (mg) - Current collector surface density (mg/cm2) * Area of the electrode (cm2)) * Active material ratio.

5. Actual weight of active material should be used when calculating specific capacity, as the coating surface density has tolerances.

1. Ultra-lightweight: It has the highest specific surface area and a specific gravity of 0.2-0.3, which is 1/4 of water, 1/3 of wood, 1/10 of aluminum, and 1/30 of iron. It is extremely lightweight.

2. Sound absorption: The porous structure exhibits wide-frequency sound absorption characteristics.

3. Electromagnetic wave shielding: It provides approximately 90dB shielding against electronic waves with its relatively thin thickness.

4. Processability: It can be cut, bent, and easily adhered.

5. Fire resistance: It maintains shape stability and is difficult to ignite, exhibiting high temperature resistance.

6. Recyclability: Metallic waste materials can be 100% recycled.

7. Thermal conductivity: The porous material has strong thermal conductivity.

8. Breathability: With a homogeneous three-dimensional network structure, it acts as a filter and exhibits excellent stability in the flow of gases and fluids.

9. Sound insulation: With additional treatment, it can achieve high noise interception and exhibits good sound insulation.

10. Exquisite appearance, practical interior: Through various processing methods, it is suitable for indoor decoration.

11. High temperature resistance of over 1100 degrees, resistance to various acid and alkali corrosion, good permeability, uniform pore structure, and fast heat transfer.
