0.2 µm 47mm Dia Hydrophobic Membrane PTFE Separator for Lithium Air Battery

Product Description

0.2 µm 47mm Dia Hydrophobic Membrane PTFE Separator for Lithium Air Battery

The PTFE (Polytetrafluoroethylene) Membrane, designed specifically as a Separator with a diameter of 47mm and  thickness from 130 to 300 microns, is a crucial consumables in Lithium Air Battery research. These membranes are sold in optional pack count and are engineered to have a pore size of 0.2 µm, which facilitates the filtration process within the battery, ensuring the separation of particles that could potentially harm the battery's performance.

One of the notable features of PTFE membrane is its compatibility with aggressive solvents, liquids, and gases, making it a robust choice for use in applications where other types of membranes might be susceptible to damage. Its resistance to a wide range of aggressive substances, including most acids, alkalis, and solvents, significantly enhances its utility in various research applications within the lithium-air battery field.

In addition to its chemical resistance properties, this PTFE membrane takes advantage of its inherently hydrophobic characteristics to perform air and gas sterilization effectively. The membrane's ability to repel water-based aerosols is instrumental in preventing contamination and maintaining the integrity of the battery's internal environment.

Specifications of PTFE Membrane Separator

• Thickness: The membranes vary in thickness from 130 to 300 microns, providing a range of options suitable for different research requirements within the lithium-air battery domain.
• Diameter: Each membrane has a uniform diameter of 47mm, ensuring a standard size that can be easily integrated into various battery designs and research setups.
• Pore Size: With a pore size ranging from 0.2 to 0.22 microns, the membrane allows for precise filtration, stopping particles that exceed this size threshold while permitting the passage of smaller molecules.
• Bubble Point: The bubble point, which indicates the pressure at which the membrane becomes permeable to gas, is between 16.0 and 24.7 psi, offering a measure of the membrane's strength against pressure differentials.
• Flow Rate: The flow rate of 8 to 13.8 ml/min per cm² at 10 psi provides an indicator of the membrane's efficiency in allowing fluids to pass through under applied pressure.
• Hydrophobicity: The inherent hydrophobic nature of the PTFE material ensures that the membrane maintains its function even in the presence of moisture or aqueous solutions.
• Pressure resistance: Can withstand much higher pressure as compared with other types of filter membranes.
• Strength: PTFE membrane discs with PP or PET supportive backing has superior dimensional strength. They can withstand aggressive handling and forceful operations, making them ideal for use in demanding industrial applications where high-strength materials are required. Additionally, their excellent dimensional strength contributes to their durability and longevity, ensuring they can withstand repeated usage without breaking down prematurely.

Packaged conveniently with each box containing 25pcs/ 50pcs/ 100pcs of these high-quality PTFE membrane discs, allowing researchers and technicians to have a ready supply for their lithium-air battery experiments and assembly needs.
