This wet process PE separator requires storage in a sealed, dry, ventilated environment to maintain its structural integrity. It is designed for lithium-rich manganese-based batteries and is sensitive to high temperatures, direct sunlight, and moisture.
- Storage Environment: Store the separator in a sealed container at room or low temperature in a dry and ventilated environment.
- Thermal Sensitivity: Avoid exposing the separator to temperatures above 135°C to prevent melting and minimize heat to avoid shrinkage.
- Transportation Precautions: During transportation, keep the separator away from direct sunlight, fire, and rain.
- Chemical Compatibility: This separator is specifically formulated for use with lithium-rich manganese-based battery electrolytes and should only be used with compatible chemistries.
- Ignition Sources: Keep the separator away from open flames and heat sources to prevent degradation or combustion.
How does the 39% porosity and 224 s air permeability of this 16 μm wet-process PE separator balance ionic conductivity and mechanical strength for lithium-rich manganese-based batteries?
The 39% porosity and 224 s air permeability provide a controlled ionic pathway while maintaining a puncture strength of 535 g and longitudinal tensile strength of 192 kg/cm³. This trade-off ensures sufficient electrolyte uptake for Li-rich Mn cathode cycling without compromising the mechanical integrity needed to prevent internal shorts from cathode volume expansion.
Why is this wet-process PE separator specifically recommended for lithium-rich manganese-based batteries rather than standard dry-process PP separators?
This separator combines a low transverse heat shrinkage of 0.1% with a melting temperature of 135°C, offering better dimensional stability and shutdown safety for Li-rich Mn systems prone to thermal runaway. The 16 μm thickness with 39% porosity and 535 g puncture strength also counters the larger volume changes and higher operating potentials typical of lithium-rich manganese oxide cathodes.
What are the critical storage and handling requirements to prevent damage or contamination of this 16 μm wet-process PE separator?
The separator must be stored in a sealed container at room or low temperature in a dry, ventilated environment, away from fire and heat sources. During handling, avoid sunlight, fire baking, and rain during transportation; the 16 μm thickness is highly susceptible to physical damage and moisture absorption, so the plastic sealed bag and buffer pad must remain intact until use.
This wet-process PE separator is specifically engineered for lithium-rich manganese-based battery chemistries, offering a thickness of 16μm with 39% porosity and 224S air permeability. Key metrics include a high puncture strength of 535g and very low transverse heat shrinkage of 0.1%, but it requires strict storage conditions and has a melting temperature of 135°C.
Positive
- Minimal transverse heat shrinkage: Transverse heat shrinkage of only 0.1% ensures dimensional stability during battery assembly and cycling, reducing short-circuit risk.
- High puncture strength for thin film: Puncture strength of 535g at 16μm thickness provides robust mechanical protection against lithium dendrites and electrode irregularities.
Trade-offs
- Requires controlled storage environment: Must be stored in a sealed container at room or low temperature, in a dry and ventilated area, away from fire and heat sources to prevent material degradation.
- Low melting temperature (135°C): The polyethylene base film melts at 135°C, limiting high-temperature safety margin and requiring careful thermal management during cell assembly and operation.
