Product Details
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.
