  • Optimized Ionic Transport: Balanced porosity (39-40%) and Gurley values (200-226 S) provide superior electrolyte wetting and consistent ion conduction, supporting stable rate capability and long-term cycling performance.
  • Comprehensive Model Selection: 7 precision configurations with substrate thicknesses from 7-20 μm and total thicknesses from 9-22 μm accommodate diverse R&D requirements from high-energy-density to high-safety battery designs.
  • Research-Grade Quality Assurance: Rigorous quality control across thickness, porosity, shrinkage, tensile strength, and puncture resistance ensures batch-to-batch consistency for reproducible battery research.

APPLICATION SCOPE: Lithium-ion battery R&D, sodium-ion battery separator evaluation, high-safety battery development, high-energy-density cell prototyping, thermal runaway prevention studies, electrolyte wettability optimization, electrode-separator compatibility testing, and academic research on advanced battery separators.
PACKAGING: Plastic-sealed bag with cushion padding to prevent physical damage during transit. Each unit contains ceramic coated separator coil at 60mm fixed width. Suitable for laboratory handling and storage.
IMPORTANT NOTICE: This ceramic coated separator is sensitive to mechanical stress and moisture. Handle with clean gloves and avoid excessive bending or creasing. Store in a dry, cool environment away from direct sunlight. Prior to cell assembly, vacuum-drying at 60-80°C for 4-8 hours is recommended to remove residual moisture. Avoid contact with sharp edges during winding and stacking processes to prevent separator puncture. For optimal performance, match separator thickness with electrode design and electrolyte formulation — please consult our engineering team for application-specific recommendations. Always check separator integrity before cell assembly to ensure consistent battery performance.

How does the 4 µm Al₂O₃ ceramic coating on the Atomfair separator trade off against ionic conductivity compared to the 20 µm PE base film?

The 4 µm ceramic coating is engineered to enhance thermal stability and chemical resistance without significantly compromising ionic conductivity, which is primarily provided by the 20 µm PE base film. The product specification states that the base film thickness of 20 µm delivers superior ionic conductivity, while the thin 4 µm coating adds safety benefits by minimizing internal short circuits.

Which electrolyte formulations are compatible with the Atomfair ceramic coated separator for lithium-ion battery research?

The separator is chemically compatible with a wide range of electrolytes, as stated in the product features, making it suitable for diverse lithium-ion applications such as prototypes, energy storage systems, electric vehicles, and portable electronics. The Al₂O₃ coating provides enhanced chemical resistance to withstand common organic electrolytes without degradation.

What handling precautions are required for the Atomfair ceramic coated separator during cell assembly to avoid damaging the 4 µm coating?

Careful handling is necessary to prevent cracking or chipping of the 4 µm Al₂O₃ ceramic layer, which could generate particulates that cause internal short circuits. The product is securely packaged for transit, and researchers should store and assemble it in a dry, clean environment to maintain coating integrity and alignment.

This 24 μm ceramic-coated separator (PE base film with 4 μm Al2O3 coating) offers enhanced thermal stability and chemical resistance for lithium-ion battery research, but the 500 m roll length may exceed the needs of early-stage prototype development.

Positive

  • Thermal and chemical coating: The aluminum oxide ceramic coating improves thermal stability and chemical resistance, reducing the risk of thermal runaway and enabling compatibility with a wide range of electrolytes.
  • Mechanically robust PE base: The 20 μm polyethylene base film provides mechanical strength and superior ionic conductivity, supporting cell cycle life and minimizing internal short circuits.

Trade-offs

  • Large roll quantity for research: Supplied as a 500 m roll, this quantity may be impractical for small-scale laboratory studies that require only a few meters of separator material.
