The Atomfair XIB-GFM separator is compatible with multiple battery chemistries including lithium, sodium, zinc, and magnesium-ion systems. Its pre-cut dimensions eliminate the need for manual trimming during coin cell assembly.
- Battery Chemistry Compatibility: The separator is suitable for use with lithium, sodium, zinc, and magnesium-ion battery electrolytes.
How does the 675 µm thickness of the Atomfair XIB-GFM separator affect electrochemical performance in CR20XX coin cells?
The 675 µm thickness provides a robust mechanical barrier while maintaining uniform porosity and stable air permeability (2.2 s/100ml/in²) as specified for the Whatman glass fiber material. This thickness optimizes electrolyte retention for lithium, sodium, zinc, and magnesium battery systems without compromising ionic transport, ensuring consistent and reproducible test data.
Can the 9 mm Atomfair XIB-GFM separator be used in sodium-ion coin cells without chemical degradation?
Yes, the Whatman glass fiber raw material complies with ISO 18782 laboratory filter material quality standards, ensuring excellent chemical inertness across multiple battery systems including sodium-ion. Its mechanical stability and uniform porosity prevent degradation in sodium electrolyte environments, providing consistent test data for academic research and new material screening.
How does the pre-cut design and ISO 286 tolerance of the Atomfair XIB-GFM separator improve handling during CR20XX coin cell assembly?
The precision pre-cut 9 mm diameter eliminates on-site cutting and trimming, reducing preparation time. The ISO 286 dimensional tolerance ensures a perfect fit within the CR20XX button battery case, preventing misalignment and short circuits during stacking, while the 675 µm thickness provides sufficient rigidity for easy handling with standard tweezers.
The Atomfair XIB-GFM pre-cut glass fiber separator, made from Whatman material, provides consistent porosity and broad battery chemistry compatibility for CR20XX coin cell research, though its fixed 9mm diameter and CR20XX-specific design limit application flexibility.
Positive
- Broad battery chemistry compatibility: Supports lithium, sodium, zinc, and magnesium-ion battery systems, enabling cross-system material comparison experiments.
- Research-grade material consistency: Whatman glass fiber ensures uniform porosity and stable air permeability, providing reproducible test data for performance evaluation.
Trade-offs
- Exclusive CR20XX format limitation: The pre-cut dimensions are engineered specifically for CR20XX button battery cases, restricting use to this coin cell format.
- Fixed pre-cut diameter: This variant is pre-cut to 9mm diameter, which may not accommodate larger electrode sizes used in some CR20XX experiments.
