Atomfair dry-process PP separator (16 μm) has specific handling and storage constraints to maintain its structural integrity and performance. The material is sensitive to moisture, heat, and mechanical puncture, and must be stored in a sealed, dry, and cool environment away from ignition sources.
- Storage Environment: Store the separator in a sealed plastic bag with buffer pad in a dry, well-ventilated area at normal or low temperature, away from fire, heat sources, and direct sunlight.
- Thermal Sensitivity: Avoid exposure to temperatures approaching the melting point of 167°C or that could cause longitudinal heat shrinkage of up to 1.6%.
- Mechanical Handling: Handle the separator with care to prevent puncture or tearing, as the puncture strength is limited to 167 g and the material is only 16 μm thick.
- Chemical Compatibility: Use the separator only with compatible electrolyte systems, as it is specifically designed for Li-rich manganese-based battery chemistries.
How does the 16μm thickness of this dry-process PP separator balance ionic conductivity and mechanical strength for Li-rich manganese-based batteries?
This separator's 16μm thickness achieves a porosity of 41% and air permeability of 210 seconds, enabling adequate ionic transport while maintaining structural integrity. The longitudinal tensile strength of 140 kg/cm³ and transverse tensile strength of 380 kg/cm³ provide the mechanical robustness needed to withstand cell assembly and cycling stresses, with a melting temperature of 167°C setting the thermal safety limit.
What are the key considerations when integrating this 16μm dry-process PP separator into a pouch cell design for Li-rich manganese-based cathodes?
The separator's longitudinal heat shrinkage of 1.6% and zero transverse heat shrinkage demand precise tension control during winding to avoid wrinkling. Its puncture strength of 167g and areal density of 8.75 g/m² affect electrode alignment and electrolyte wetting; the 60mm width and 10-meter length are tailored for prototype pouch cell fabrication.
What are the critical storage and handling requirements to prevent contamination or mechanical damage to this 16μm dry-process PP separator?
The separator must be stored sealed in a normal or low temperature, dry, and well-ventilated environment, away from fire and heat sources. During transport, avoid sunlight, fire baking, and rain. The thin 16μm film is susceptible to wrinkles and tears, so handling should be performed with clean gloves in a cleanroom environment.
This Atomfair dry-process PP separator (16μm, 60mm×10m) is optimized for Li-rich manganese-based batteries, offering high transverse tensile strength (380 kg/cm³) and zero transverse heat shrinkage, but with moderate puncture resistance (167 g) and stringent storage requirements.
Positive
- High Transverse Tensile Strength: With a transverse tensile strength of 380 kg/cm³, this dry-process PP separator provides robust mechanical support in the lateral direction, enhancing durability during cell winding and assembly.
- Zero Transverse Heat Shrinkage: The 0% transverse heat shrinkage (TD) ensures excellent dimensional stability under thermal stress, minimizing internal short-circuit risks in high-temperature battery operations.
Trade-offs
- Moderate Puncture Resistance: At 167 g puncture strength, this separator is less resistant to dendritic penetration than thicker wet-process alternatives, requiring careful cell design for high-energy-density anodes.
- Controlled Storage Requirements: The separator must be stored sealed in a dry, low-temperature, well-ventilated environment, away from heat and sunlight, to maintain its mechanical and thermal performance.
