Glass Fiber 2916 Battery Separator (GF/A): The Research-Standard Separator for Testing New Electrode Materials, Now Available in Indonesia

When battery researchers want to test the true performance of a new electrode material, they deliberately avoid the microporous polymer separators used in commercial batteries, since the added ionic resistance those separators introduce can obscure the actual results of the material under evaluation. The solution is a glass fiber separator with porosity above 90%, far higher than commercial polymer separators, which typically sit below 50%, adding almost no resistance to electrolyte ion movement. ITNANO's Glass Fiber 2916 (GF/A 2916) is exactly this kind of separator, specifically designed to be electrochemically "invisible" in battery material research testing.

Research labs in Indonesia have typically had to import glass fiber separators with genuinely consistent porosity and aperture. An inconsistent separator can actually become an unnoticed confounding variable when comparing electrode material performance across test cells. That's starting to change.

ITNANO (CV. Inovasi Teknologi Nano), based at the NRE Lab in Medan, provides Glass Fiber 2916 Battery Separator for battery research and development in Indonesia. Here's what a glass fiber separator actually is, why its porosity matters so much, and where this material is being used in research and laboratories today.

What Is Glass Fiber 2916 Separator?

Glass Fiber 2916 is a non-woven sheet built from glass fibers with an average diameter of around 5 micrometers, interwoven into a porous structure that offers excellent chemical resistance, good electrical insulation, and effectively allows electrolyte ions to pass through the membrane without significant resistance.

Porosity and aperture size are the biggest factors in Glass Fiber 2916's performance as a separator, since both directly affect how easily electrolyte ions can move across the membrane, as well as the separator's ability to prevent direct contact between the positive and negative electrodes. ITNANO's Glass Fiber 2916 has a basis weight of 66 g/m², an aperture of 1.63 micrometers, a thickness of 0.29 mm (at 100 kPa), a porosity above 90%, and is available in a 13 × 5 cm size.

Where Glass Fiber 2916 Is Being Used

Research battery and supercapacitor separators

This is Glass Fiber 2916's primary application: as a separator in laboratory-scale battery and supercapacitor cells, physically separating the positive and negative electrodes while still allowing effective electrolyte ion movement, ideal for testing and comparing new electrode material performance without the separator becoming a limiting factor.

Water filtration and environmental analysis

Beyond battery applications, GF/A-grade glass fiber like this is also widely used as a standard filter paper for water filtration, environmental analysis, and laboratory particle separation, drawing on its high porosity and good chemical resistance.

Why Source Glass Fiber Separators from ITNANO

Because a separator's job in a research context is to be electrochemically "invisible," consistency in porosity and aperture is far more critical than in commercial separator applications. A separator with porosity that varies between batches can become an unnoticed confounding variable when comparing electrode material performance across different test cells. ITNANO provides Glass Fiber 2916 with directly verifiable specifications, giving labs in Indonesia a consistent research-grade separator without needing to wait through a long import process.

Whether you're testing new electrode materials, assembling research battery or supercapacitor cells, or need filter paper for water filtration and environmental analysis applications, ITNANO's Glass Fiber 2916 gives you a porosity and aperture consistency that a distant supplier can't guarantee after shipping, without the import wait.
