Key Product Features & Benefits
  • High Filtration Efficiency: Achieves an uncompromised efficiency rating over 99.95%, delivering safe, effective isolation of electrodes.
  • Outstanding Thermal Stability: Safely withstands continuous operating thermal conditions up to 500 °C, perfectly suited for high-temperature testing loops.
  • Excellent Fluid Permeability: Maintains a balanced 62 Herzberg transport rate to optimize smooth, unimpeded internal electrolyte ion migration.
  • Convenient Box Setup: Packaged carefully at 100 sheets per box, ideal for rapid research deployment and repeatable experimentation runs.

Target Application Fields
  • Lithium-Ion Battery Prototyping: Deployed as a heavy-duty matrix separator within cell assemblies to maximize runtime stability and device safety metrics.
  • Academic & Industrial Research: Serves as an uncompromised high-precision baseline standard for advanced energy storage technology developments.
  • Diverse Energy Storage Architectures: Highly applicable across variable alternative testing configurations requiring reliable, porous separator networks.

QUALITY REGULATION: Microfiber porosity metrics and raw fiber distributions adhere strictly to [ISO 18782 laboratory filter material quality standards] to prevent variable baseline drift.
HANDLING LOGISTICS: Use appropriate personal protective apparel when handling fine sheets; avoid the inhalation of raw glass fiber dust particles.
STORAGE RECOMMENDATIONS: Store inside a clean, dry location safely protected away from moisture and out of reach of children to ensure absolute sheet integrity.
PACKAGING ASSURANCE: Supplied in boxes of 100 sheets to guarantee maximum material quality and avoid edge damage during transport operations.
IMPORTANT NOTICE: Transfer and place separator discs inside controlled atmospheres to prevent environmental humidity drift before testing. For alternative custom box counts, tailored edge width requests, or volume quotation matrices, reach out to our team at support@atomfair.com.

The separator must be handled with protective equipment to avoid inhalation of glass microfibers. The material must not be exposed to temperatures exceeding 500°C to maintain structural integrity.

  • Temperature Limit: The separator must not be used at temperatures above 500°C to prevent thermal degradation or failure.
  • Dust Inhalation Hazard: Use appropriate respiratory protection and avoid creating airborne dust when handling the glass fiber sheets.

What is the trade-off between the high filtration efficiency (>99.95%) and the permeability (62 Herzberg) in the Whatman GF/A battery separator for lithium-ion research?

The Whatman GF/A separator achieves >99.95% filtration efficiency through its 1.6 μm pore size and 260 μm thickness, which effectively prevents short circuits. This high efficiency is balanced by a permeability of 62 Herzberg and an air flow rate of 4.3 Gurley, enabling adequate ion transport for battery operation.

How does the 2.1 cm diameter of the Whatman GF/A separator constrain its use in different battery cell geometries?

The 2.1 cm diameter is specifically sized for small-scale research cells such as coin cells. The separator is supplied as pre-cut discs, 100 per box, convenient for batch assembly of multiple test cells without additional cutting.

What are the storage and handling requirements for the Whatman GF/A glass fiber separator to maintain its integrity in research settings?

The separator must be stored in a dry place away from moisture to prevent degradation. When handling, appropriate protective equipment should be used and inhalation of dust avoided. The glass fiber material can withstand working temperatures up to 500°C, allowing use in high-temperature battery tests.

This Whatman GF/A glass fiber separator offers over 99.95% filtration efficiency and thermal stability up to 500°C for lithium-ion battery research. However, it requires careful handling to avoid dust inhalation and dry storage to prevent moisture absorption.

Positive

  • High Filtration Efficiency: Achieves >99.95% filtration efficiency, ensuring effective separation of electrodes and preventing short circuits in battery cells.
  • Exceptional Thermal Stability: Withstands working temperatures up to 500°C, making it suitable for high-temperature battery applications without degradation.

Trade-offs

  • Dust Hazard During Handling: Glass fiber dust may be generated; appropriate protective equipment and avoidance of inhalation are required per safety instructions.
  • Moisture Sensitivity: Must be stored in a dry place away from moisture, as glass fiber separators can absorb ambient humidity and affect performance.
