Core Functional Advantages
- Superior Chemical Resistance
The high-purity PTFE material delivers outstanding acid, alkali, and solvent resistance, withstanding corrosion from aggressive electrolytes, liquids, and gases in lithium-air battery systems. It avoids the degradation and failure issues common with traditional separators, ensuring stable experimental conditions. - Precise Hydrophobic & Gas Permeable Design
With a precisely controlled 0.2–0.22um pore size, the separator effectively blocks water-based aerosols while enabling unimpeded gas transmission—critical for lithium-air battery operation. Its hydrophobicity also prevents moisture intrusion, eliminating side reactions caused by water contamination. - Stable & Consistent Performance
Tight tolerance ranges for thickness, pore size, and flow rate ensure batch-to-batch consistency, reducing experimental variability and improving the reliability of lithium-air battery R&D data. The rigid PTFE structure maintains dimensional stability even under harsh testing conditions.
