This separator must be stored sealed in a dry, low-temperature, ventilated environment away from heat and ignition sources. Handling requires an anhydrous inert gas atmosphere to prevent moisture and oxygen contamination that degrades performance.
- Storage Requirement: Store sealed in a normal or low temperature, dry, and ventilated environment away from fire and heat sources.
- Transport Protection: Avoid exposure to sunlight, baking, or rain during transportation to prevent material degradation.
- Inert Gas Handling: Keep containers tightly sealed or handle exclusively within an anhydrous inert gas environment to prevent phase contamination.
- Thermal Shrinkage Consideration: Thermal shrinkage under high temperature is minimal in both machine and transverse directions but must be accounted for during cell assembly.
How does the ceramic coating thickness impact the thermal shrinkage and puncture strength of the AF-TCA series separators?
The ceramic coating thickness influences both thermal shrinkage and puncture strength. Across all model configurations, MD shrinkage ranges from 0.5% to 0.7% and TD shrinkage is 0.1%, while puncture strength varies from 405g to 515g depending on the specific base and coating thickness combination. The advanced alumina coating provides structural reinforcement to reduce dimensional contraction under high-temperature loads.
What electrolyte systems are compatible with the Al2O3 ceramic coated PE separator?
The separator is designed for lithium-ion battery electrolytes and features optimized electrolyte wettability due to the homogeneous Al2O3 particle distribution on the PE matrix. The controlled porosity (39%-40%) and stable Gurley air permeability (200s-226s) facilitate stable lithium-ion transport kinetics. However, specific electrolyte compatibility should be validated in your cell chemistry, as the product is intended for research applications.
What are the critical storage and handling requirements for the ceramic coated PE separator to prevent degradation?
The separator must be stored sealed in a normal or low temperature, dry, and ventilated environment, away from fire and heat sources. Avoid exposure to sunlight, baking, and rain during transportation. The product is highly sensitive to ambient exposure; containers should be kept tightly sealed or handled exclusively within an anhydrous inert gas environment to prevent phase contamination or degradation before use.
This ceramic-coated PE separator series provides high thermal stability and uniform porosity for consistent lithium-ion battery testing, but requires strict ambient control and exhibits anisotropic thermal shrinkage.
Positive
- Homogeneous Al2O3 coating for consistent performance: Uniform alumina particle distribution across PE matrix ensures consistent electrochemical stability and thermal tolerance across the separator surface.
- Optimized porosity and Gurley values for low resistance: Porosity of 39-40% and Gurley air permeability of 200-226s facilitate stable lithium-ion transport kinetics and low internal resistance during cycling.
Trade-offs
- Ambient exposure sensitivity requires strict handling: The product is highly sensitive to ambient exposure; containers must be kept tightly sealed or handled exclusively in an anhydrous inert gas environment to prevent phase contamination.
- Anisotropic thermal shrinkage between MD and TD: MD shrinkage (0.5-0.7%) is significantly higher than TD shrinkage (0.1%), requiring careful alignment in cell assembly to avoid anisotropic dimensional changes under thermal load.
