With a thickness of 0.29 mm and a pore size of 1.63 μm, GF/A OL2916 provides a balanced combination of thickness, electrolyte absorption, and mechanical strength.
It is suitable for conventional coin cells, pouch cells, aqueous batteries, and organic electrolyte battery research. It can be used as a single layer or stacked in multiple layers.
With a thickness of 0.62 mm and a pore size of 2.76 μm, GF/D OL6227 is the thickest model in the series.
It provides high electrolyte uptake and strong mechanical support, making it suitable for scientific testing, long-cycle studies, and systems requiring enhanced electrolyte retention.
In certain compatible test systems, cycle life may exceed 20,000 cycles. Actual performance depends on the battery chemistry, electrode materials, electrolyte composition, cell design, and test conditions.
With a thickness of 0.20 mm and a pore size of 1.20 μm, GF/F OL2012 is the thinnest model and has the smallest pore size in the series.
It is suitable for thin pouch cells, stacked-cell configurations, and experiments with strict separator thickness requirements. Because of its thin structure, multiple layers may be used when required.
The DiffuLayer® OL Series is suitable for research on:
Aqueous zinc-ion batteries
Zinc–iodine batteries
Sodium-ion batteries
Aluminum-ion batteries
Lithium battery systems
Metal–air batteries
Other liquid-electrolyte electrochemical systems
Select the appropriate model according to the cell structure and experimental requirements.
Cut the separator to fully cover the electrode area.
Use powder-free gloves and clean tweezers to prevent contamination.
Add sufficient electrolyte before assembly to ensure complete wetting.
Keep the separator flat and free from damage or wrinkles to prevent direct contact between the positive and negative electrodes.
For comparative experiments, keep the separator area, number of layers, electrolyte volume, and assembly pressure consistent.
| Application Requirement | Recommended Model |
|---|---|
| General coin-cell or pouch-cell research | GF/A OL2916 |
| High electrolyte uptake and long-cycle studies | GF/D OL6227 |
| Thin cells, stacked structures, or small-pore requirements | GF/F OL2012 |
| Model not yet determined | Test all three models under identical conditions |
Choose GF/A OL2916 for general-purpose experiments, GF/D OL6227 for high electrolyte uptake and long-cycle research, and GF/F OL2012 for thin cells or stacked configurations.
Yes. Full wetting with the electrolyte is recommended before assembly to avoid local dry areas that may affect cell performance.
GF/F OL2012 is relatively thin. It may be used as a single layer or stacked in multiple layers depending on the electrode surface, assembly pressure, and electrolyte uptake requirements.
Yes. Rolls, square sheets, circular discs, and customized widths, lengths, diameters, and quantities are available.
GF/A OL2916 is suitable for general-purpose battery research, GF/D OL6227 is designed for high electrolyte uptake and long-cycle studies, and GF/F OL2012 is ideal for thin and stacked-cell structures.
