This separator requires storage in a sealed, dry, and ventilated environment at normal or low temperature. It must be kept away from fire, heat sources, and direct sunlight to prevent thermal or mechanical degradation.
- Storage Environment: Store the separator in a sealed, dry, and ventilated environment at normal or low temperature.
- Thermal Safety: Keep away from fire and heat sources to prevent thermal degradation or fire hazard.
- Light Exposure: Avoid direct sunlight exposure during storage and transportation.
- Moisture Protection: Protect from rain and moisture during transportation to prevent contamination.
- Mechanical Protection: Use the provided buffer pad to prevent mechanical damage during handling.
Follow these steps to ensure the separator remains free from contamination and physical damage. Proper storage conditions preserve its mechanical and thermal properties for battery assembly.
Required Equipment: Plastic Sealed Bag, Buffer Pad
- Inspect Packaging
Inspect the packaging for any signs of damage or contamination upon receipt. - Place in Sealed Bag
Transfer the separator to a sealed plastic bag with the buffer pad for protection. - Store in Controlled Environment
Store the sealed bag in a dry, ventilated environment at normal or low temperature. - Maintain Distance from Hazards
Keep the separator away from fire, heat sources, and direct sunlight at all times. - Ensure Dry Conditions
Confirm that the storage area is free from moisture and rain exposure.
How does the 9 μm thickness and 38% porosity of this wet process PE separator balance ionic conductivity with mechanical integrity for lithium-rich manganese-based cells?
The 9 μm thickness reduces ionic path length, while the 38% porosity ensures adequate electrolyte uptake without compromising mechanical performance. This trade-off is evidenced by the 185 s air permeability and 410 g puncture strength, which together support sufficient ion transport and resistance to electrode penetration.
Is this 9 μm PE separator specifically designed for lithium-rich manganese-based cathodes requiring high voltage stability and low thermal shrinkage?
Yes, this separator is optimized for lithium-rich manganese-based batteries, as indicated by its product name and specifications. The 135°C melting temperature and transverse heat shrinkage of only 0.1% provide dimensional stability under thermal stress, while the 221 kg/cm³ longitudinal tensile strength resists deformation during cell assembly and cycling.
What storage and handling precautions are required to maintain the integrity of this 9 μm wet process PE separator before use?
Store the separator sealed in a normal or low temperature, dry, and ventilated environment. Keep away from fire, heat sources, sun exposure, and rain during transportation to prevent mechanical damage or oxidation that could compromise the 9 μm thin film.
This 9μm wet-process PE separator offers a longitudinal tensile strength of 221 kg/cm³ and transverse heat shrinkage of only 0.1%, providing robust mechanical integrity and dimensional stability for lithium-rich manganese-based battery cells. However, its 135°C melting point and strict storage requirements (sealed, dry, away from heat/sun) demand careful thermal management and handling protocols.
Positive
- High Longitudinal Tensile Strength: With 221 kg/cm³ longitudinal tensile strength, the separator withstands winding tension and cell assembly stresses without tearing, enhancing production yield.
- Low Transverse Heat Shrinkage: Transverse heat shrinkage of only 0.1% ensures minimal dimensional change during thermal processing, maintaining consistent electrode isolation and reducing short-circuit risk.
Trade-offs
- Moderate Melting Temperature: The PE base film melts at 135°C, limiting thermal stability; the separator may soften or shrink appreciably at temperatures above this threshold, requiring careful thermal management in cell operation.
- Stringent Storage Requirements: The separator must be stored sealed in a dry, ventilated environment away from heat sources and direct sunlight, and protected from moisture and physical damage during transport to prevent property degradation.
