What is the maximum operating temperature of the Glass Fiber Battery Separator Base Film 290μm?
The product description states the material is 'thermally stable' but does not specify a maximum operating temperature. Therefore, no specific temperature limit can be provided without fabricating data. For precise thermal limits, contact the manufacturer.
How does the 290μm thickness affect the separator's porosity and air permeability?
The separator has a porosity of >90% and a pore size of 1.63 μm, with a basis weight of 66 g/m². The 290μm thickness (measured at 100 kPa) contributes to balanced porosity and good air permeability, as stated in the key features. However, the description does not provide a direct quantitative relationship between thickness and permeability.
Is the Glass Fiber Battery Separator Base Film 290μm compatible with aqueous and organic electrolyte systems?
The material is described as hydrophilic and binder-free, which suggests good wettability with aqueous electrolytes. However, the product description does not explicitly state compatibility with organic electrolytes or specific battery chemistries. For application-specific compatibility, consult the manufacturer.
This 290 μm glass fiber separator base film, supplied as a 100 mm x 100 m roll, offers a high-porosity (>90%) hydrophilic substrate with a uniform pore size of 1.63 μm, making it suitable for battery separator and filtration applications requiring thermal stability and binder-free construction.
Positive
- High porosity and uniform pore size: With porosity exceeding 90% and a pore size of 1.63 μm, this separator provides balanced air permeability and consistent ionic transport, critical for battery performance and filtration efficiency.
- Hydrophilic and binder-free: The binder-free, hydrophilic nature ensures excellent electrolyte wetting without introducing organic binders that could degrade electrochemical performance, while maintaining thermal stability for high-temperature processes.
Trade-offs
- Thickness variation between lots: Slight variations in thickness and other properties may occur between production lots, which could affect consistency in applications requiring tight dimensional tolerances.
- Handling fragility due to glass fiber: As a glass fiber material, the separator may be prone to mechanical damage during handling or cutting, requiring careful processing to avoid tears or edge damage.
