The separator is chemically resistant to aggressive electrolytes and solvents used in lithium-air battery systems. It provides a hydrophobic barrier against moisture and aerosols to prevent side reactions.

Chemical Compatibility: The separator withstands corrosion from aggressive electrolytes, acids, and solvents.
Moisture Barrier: The separator blocks water-based aerosols and prevents moisture intrusion.
Gas Permeability: The separator enables unimpeded gas transmission.
Dimensional Stability: The separator maintains dimensional stability under harsh testing conditions.

FAQ

How does the 0.2–0.22 μm pore size range affect bubble point and flow rate for lithium-air battery separator performance?

The specified pore size range yields a bubble point of 16.0–24.7 psi and a flow rate of 8–13.8 ml/min·cm² at 10 psi. This trade-off ensures the separator effectively blocks water-based aerosols (hydrophobic barrier) while maintaining sufficient gas permeability for cathode oxygen access—both critical for lithium-air cell operation. The tight pore size tolerance keeps performance consistent across batches.

Can this PTFE separator be used with organic electrolytes and aggressive solvents typical in lithium-air battery research?

Yes, the high-purity PTFE material provides outstanding acid, alkali, and solvent resistance, withstanding corrosion from aggressive electrolytes and liquids common in lithium-air systems. The raw material complies with ISO 10993 standards for chemical inertness, ensuring no adverse reactions with electrolytes or electrode materials. This prevents degradation and failure issues seen with traditional separators.

What handling and storage conditions are required to preserve the hydrophobicity and pore integrity of this PTFE separator?

Store the separator in a dry, clean environment to maintain its hydrophobic property and prevent moisture intrusion. The PTFE material inherently resists moisture and blocks water aerosols as designed, but contamination or physical damage can alter pore structure. Keep in the original packaging (100 pieces per box) until use to avoid dust and mechanical stress that could compromise dimensional stability.

Assessment

This Atomfair PTFE separator provides high chemical resistance and precise hydrophobic gas permeability for lithium-air battery R&D, but is explicitly designed for research-scale use and dedicated to lithium-air cell applications.

Positive

Superior chemical resistance to aggressive electrolytes: High-purity PTFE withstands corrosion from strong acids, alkalis, and solvents used in lithium-air battery experiments, preventing separator degradation and ensuring stable test conditions.
Precise hydrophobic gas-permeable design: Controlled 0.2–0.22 µm pore size blocks water-based aerosols while enabling unimpeded oxygen transmission, critical for lithium-air battery operation and moisture intrusion prevention.

Trade-offs

Application limited to lithium-air R&D: This separator is explicitly tailored for lithium-air battery research and material compatibility testing, not validated for other battery chemistries or general separation tasks.
Not intended for production-scale use: Marketed as a research-dedicated component, it is optimized for laboratory experimental cell assembly and is not specified for pilot or commercial manufacturing lines.
