Description

ATOMFAIR® WET PE SEPARATOR 12ΜM 60MM X 10M

RESEARCH GRADE BATTERY SEPARATOR

Product Overview
The ATOMFAIR® Wet PE Battery Separator is a premium research-grade polyethylene separator engineered for lithium-ion and sodium-ion battery R&D. Featuring a wet-process microporous structure with exceptional uniformity, this 12μm separator delivers superior ionic transport with 40% porosity and 222 S Gurley value. The PE material provides inherent thermal shutdown capability at 135°C, enhancing battery safety during thermal runaway events. With fixed 60mm width and 10-meter roll length, this product is ideal for laboratory-scale coin-cell and pouch-cell assembly. Mechanical performance includes puncture strength of 566g and tensile strength of 208 kg/cm² (MD) / 167 kg/cm² (TD). Exceptional dimensional stability (TD shrinkage ≤ 0.1%, MD shrinkage 0.9%) ensures reliable performance at elevated temperatures. Plastic-sealed bag packaging with cushion padding provides secure protection for laboratory handling and storage. Competitive PE separator film price points are available for both academic and industrial R&D procurement.

Key Features & Advantages
  • Thermal Shutdown Safety: 135°C melting point provides rapid shutdown capability during thermal runaway events, enhancing battery safety by blocking ion conduction at elevated temperatures.
  • Superior Dimensional Stability: Exceptional thermal shrinkage control with TD shrinkage ≤ 0.1% and MD shrinkage of 0.9%, effectively preventing separator contraction and short-circuit risks.
  • Optimized Porosity & Wettability: Balanced 40% porosity and 222 S Gurley value deliver superior electrolyte wetting and consistent ionic transport for reliable electrochemical testing.
  • Balanced Mechanical Strength: 566g puncture strength with 208/167 kg/cm² tensile strength provides robust mechanical protection while maintaining flexibility for coin-cell assembly.
  • Research-Grade Quality Assurance: Rigorous quality control across all specifications ensures batch-to-batch consistency for reproducible coin-cell and pouch-cell assembly in laboratory and pilot-scale research.

APPLICATION SCOPE: Lithium-ion battery R&D, sodium-ion battery testing, coin-cell (CR2032, CR2025) assembly, pouch-cell prototyping, high-energy-density battery development, thermal runaway prevention studies, electrolyte wettability optimization, separator material benchmarking, and academic research on advanced battery separators.
PACKAGING: Plastic-sealed bag with cushion padding to prevent physical damage during transit. Each unit contains 10-meter separator roll at 60mm fixed width. Suitable for laboratory handling and storage. Store in cool, dry, ventilated environment away from ignition and heat sources.
IMPORTANT NOTICE: Wet PE separator is sensitive to mechanical stress, moisture, and high-temperature exposure. Handle with clean gloves and avoid excessive bending, creasing, or sharp-edge contact during cutting and stacking operations. 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, vacuum-drying at 60-80°C for 4-8 hours is recommended to remove residual moisture and ensure optimal electrolyte wetting. When pairing with electrolytes, ensure compatibility with PE separator chemistry — avoid aromatic hydrocarbons and aggressive solvents that may degrade PE. Always check separator integrity for any physical damage before cell assembly. Avoid exposure to temperatures exceeding 135°C to prevent melting and structural degradation.

This polyethylene battery separator is sensitive to ambient moisture and must be stored in a dry, ventilated environment below the melting point of 135°C. Mechanical integrity is compromised by puncture forces exceeding 566 g and thermal shrinkage exceeding 0.9% in the machine direction.

  • Moisture sensitivity: The separator must be kept sealed in a dry atmosphere to prevent water uptake which can degrade ionic conductivity and induce swelling.
  • Thermal exposure: Exposure to temperatures approaching 135°C will cause melting and loss of electrical isolation between electrodes.
  • Mechanical handling: Severe collision or extrusion during transport can exceed the puncture strength of 566 g and cause critical pinhole defects.

How does the mechanical strength of the 9μm wet PE separator compare to the 12μm variant, and what trade-offs exist for thin-film applications?

The 9μm separator delivers a higher longitudinal tensile strength of 221 kg/cm³ compared to 208 kg/cm³ for the 12μm variant, but its puncture strength drops to 410g from 566g. This trade-off improves ion transport via lower air permeability (185S vs 222S) at the cost of reduced puncture resistance, requiring careful handling during high-pressure cell assembly to avoid micro-shorts.

What are the thermal shrinkage properties of the 9μm PE separator and how do they affect cell lamination and safety?

The separator exhibits longitudinal thermal shrinkage of 1.5% and transverse shrinkage of only 0.1%, with a melting temperature of 135°C. The minimal transverse shrinkage ensures stability during lamination, while the 1.5% MD shrinkage must be accounted for in electrode alignment to prevent internal shorts, and the 135°C shutdown temperature provides a safety mechanism against thermal runaway.

What storage conditions are critical to preserve the porosity and permeability of this wet PE separator for reproducible battery research?

The separator must be stored sealed in a dry, well-ventilated environment at normal or low temperature, away from fire and flammable materials. Air permeability of 185 seconds and porosity of 38% are susceptible to moisture and heat; therefore, immediate resealing after use and avoidance of sunlight or rain exposure are mandatory to maintain consistent performance across experiments.

This 12 μm wet-process PE separator provides high tensile strength (MD 208 kg/cm³) and puncture resistance (566 g) with low thermal shrinkage (MD 0.9%, TD 0.1%), ideal for battery research requiring mechanical robustness. However, its melting point of 135°C and requirement for dry, sealed storage impose operational constraints.

Positive

  • High mechanical strength: Longitudinal tensile strength of 208 kg/cm³ and puncture strength of 566 g provide robust isolation between electrodes, reducing short-circuit risk during cell assembly and cycling.
  • Low thermal shrinkage: MD shrinkage of only 0.9% and TD shrinkage of 0.1% at elevated temperatures ensure dimensional stability, maintaining separator integrity and ion transport pathways.

Trade-offs

  • Low melting temperature: A melting point of 135°C limits high-temperature applications and thermal runaway tolerance, requiring careful thermal management in battery testing.
  • Requires dry, sealed storage: The separator must be stored sealed in a dry, well-ventilated environment to prevent moisture absorption that could compromise ionic conductivity and mechanical properties.
