Key Features & Advantages
  • Li-Rich Mn Cathode Optimized: Dual-process separator portfolio specifically designed for lithium-rich manganese cathode systems, offering tailored safety and performance characteristics for high-voltage (≥ 4.6V) battery R&D.
  • Superior Thermal Safety: Dry PP separators deliver exceptional high-temperature stability with MD shrinkage as low as 1.1% and 167°C melting point; wet PE separators provide low-temperature shutdown at 135°C for rapid thermal runaway prevention.
  • Exceptional Mechanical Performance: Wet PE separators achieve outstanding puncture resistance up to 722g (PE20) and tensile strength up to 221 kg/cm², ensuring reliable processing during high-speed winding and assembly operations.
  • Optimized Ionic Transport: Uniform porosity (38-41%) with Gurley values from 155-355 seconds supports superior electrolyte wetting and consistent ion transport for Li-rich Mn cathode systems.
  • Comprehensive Model Selection: 9 precision models across two separator technologies with thickness options from 7-25μm accommodate diverse R&D requirements from ultra-thin consumer batteries to robust power battery systems.

APPLICATION SCOPE: Lithium-rich manganese cathode battery R&D, high-voltage lithium-ion battery development, high-energy-density cell prototyping, power battery evaluation, consumer battery research, high-rate fast-charging studies, thermal runaway prevention research, separator material comparison, electrolyte wettability optimization, and academic research on advanced battery separators for next-generation cathode materials.
PACKAGING: Plastic-sealed bag with cushion padding to prevent physical damage during transit. Each unit contains separator coil at 60mm fixed width. Suitable for laboratory handling and storage. Store in cool, dry, ventilated environment away from ignition and heat sources.
IMPORTANT NOTICE: Both dry PP and wet PE separators are sensitive to mechanical stress, moisture, and high-temperature exposure. Handle with clean gloves and avoid excessive bending, creasing, or sharp-edge contact. Store in a cool, dry, ventilated environment away from direct sunlight, ignition sources, and heat sources. Protect from rain and moisture during transportation. Prior to cell assembly with Li-rich Mn cathodes, vacuum-drying at 60-80°C for 4-8 hours is recommended to remove residual moisture. When pairing with lithium-rich manganese cathodes, ensure electrolyte is compatible with high-voltage operation (≥ 4.6V) — recommended electrolyte additives include FEC and other film-forming agents. For optimal performance, select separator type based on application requirements: dry PP for high-temperature stability (power batteries), wet PE for high-rate capability (consumer batteries). Always check separator integrity before cell assembly to ensure consistent battery performance. Avoid exposure to temperatures exceeding melting points (PP: 167°C, PE: 135°C) to prevent structural degradation.

This battery separator requires controlled storage in a sealed, dry, and well-ventilated environment away from heat sources. It exhibits defined thermal shrinkage and mechanical strength properties that must be considered during handling and battery assembly.

  • Storage Environment: Store sealed in a dry, ventilated area at normal or low temperature, protected from fire, direct sunlight, and rain.
  • Thermal Stability: Avoid exposure to temperatures approaching the melting point of the base film (PE: 135°C, PP: 167°C) to prevent shrinkage or melting.
  • Mechanical Integrity: Handle with care using buffer pads to prevent puncture, tearing, or deformation during transport and assembly due to the thin film structure.
  • Chemical Compatibility: Verify compatibility with the intended electrolyte and electrode materials prior to use, as the separator is optimized for lithium-rich manganese-based battery systems.

How do the thermal and mechanical properties of the wet-process PE separator compare to the dry-process PP separator for lithium-rich manganese-based battery applications?

The wet-process PE separator (AF-PE series) has a melting temperature of 135°C, while the dry-process PP separator (AF-PP series) melts at 167°C, offering superior thermal resistance for high-temperature operation. However, PE separators provide significantly higher puncture strength (up to 722g for 20μm thickness) compared to PP (167g max), making PE more effective against dendrite penetration. The choice depends on whether thermal shutdown or mechanical robustness is prioritized for the specific cell design.

Can these 60mm-wide separators be used directly in standard coin cell or pouch cell assembly without modification?

Yes, the 60mm width is compatible with typical laboratory-scale electrode cutting and cell assembly processes for coin cells and small pouch cells. The available thicknesses range from 7μm to 25μm across both PE and PP series, allowing selection based on the desired balance of ionic conductivity and mechanical integrity for lithium-rich manganese-based chemistry. For custom widths or further integration requirements, contact the supplier for modifications.

What are the recommended storage and handling conditions to prevent degradation of these battery separators?

Store the separators sealed in a normal or low temperature, dry, and well-ventilated environment, away from fire and heat sources. During transportation, avoid exposure to sunlight, fire baking, and rain to prevent physical or thermal damage. The packaging uses plastic sealed bags with buffer pads to ensure protection during handling and storage.

This series of PE and PP battery separators tailored for lithium-rich manganese-based research cells provides a wide thickness selection (7-20 μm for PE, 16-25 μm for PP) and near-zero transverse heat shrinkage, enabling precise experimental tuning. However, the fixed 60 mm width and strict storage requirements (sealed, dry, cool, away from ignition sources) impose handling and scalability constraints for certain lab setups.

Positive

  • Broad thickness range for research flexibility: The separator is available in multiple thicknesses (PE: 7/9/12/14/16/20 μm; PP: 16/20/25 μm), allowing researchers to systematically study the effect of separator thickness on battery performance in lithium-rich manganese-based systems.
  • Exceptional transverse dimensional stability: Transverse heat shrinkage is ≤0.1% for all variants, minimizing the risk of electrode exposure and internal short circuits during battery assembly and thermal cycling.

Trade-offs

  • Stringent storage and handling conditions: The separator must be kept sealed in a dry, well-ventilated environment away from heat sources, sunlight, and rain, requiring controlled laboratory storage and careful inventory management to avoid degradation.
  • Fixed 60 mm width limits scalability: All variants are cut to a standard 60 mm width, which may not accommodate larger electrode formats or pouch cell prototypes without additional slitting or custom ordering, adding process steps for some research workflows.
