Nickel Foam for Button Batteries

1. High Porosity and Large Specific Surface Area: Nickel foam typically has a porosity of 95% - 98%, providing a very large specific surface area that significantly improves electrode reaction efficiency in batteries.

2. Excellent Conductivity: The three-dimensional conductive network structure of nickel foam effectively reduces internal resistance, enhancing the overall efficiency and performance of button batteries.

3. Good Chemical Stability: Nickel offers excellent corrosion resistance, especially in electrolyte environments, ensuring stable battery performance over long-term use.

4. Lightweight Structure with High Mechanical Strength: Nickel foam is lightweight while maintaining good mechanical strength, allowing for reduced battery weight without compromising structural stability.

5. Easy to Process and Form: Nickel foam can be easily cut and shaped according to specific button battery requirements, ensuring a perfect fit with the internal battery structure.

1. Button Battery Electrode Substrate: Nickel foam is widely used as an electrode material for silver oxide, lithium-ion, and nickel-metal hydride button cells. Its high porosity and excellent conductivity significantly enhance battery current output and capacity.

2. Supercapacitors: Due to its large specific surface area and excellent conductivity, nickel foam is also suitable for use in button-type supercapacitors, enabling rapid energy storage and release.

3. Other Micro Batteries: Nickel foam is also used in other types of micro batteries, such as those for sensors, computer motherboards, watches, and other small electronic devices, providing stable and reliable power support.

· High Current Efficiency: The three-dimensional porous structure increases the current density of electrode materials, reducing polarization effects and improving the charge/discharge efficiency of the battery.

· Corrosion Resistance and Chemical Stability: Nickel material can withstand corrosion and chemical changes over the long term, making it suitable for harsh electrolyte conditions found in batteries.

· Lightweight and High Strength: Nickel foam is lightweight yet retains sufficient mechanical strength, making it suitable for the compact design requirements of button cells.

· Flexible Customization and Easy Processing: Nickel foam can be cut and shaped to fit various button battery needs, providing high flexibility to meet diverse battery design requirements.

Nickel foam is typically packaged in flat sheets or rolls and protected using moisture-proof and anti-oxidation materials to ensure the product's integrity and performance during transit and storage. We also offer customized packaging solutions to ensure safe delivery to customers.
