ATOMFAIR® WET-PE SEPARATOR 60mm (9-20µm)

RESEARCH GRADE MATERIAL

Product Overview
The ATOMFAIR® Wet-PE Separator 60mm is a premium-grade polyethylene battery separator engineered for advanced lithium-ion R&D applications. Available in four precision thickness grades – 9, 12, 16, and 20µm – this separator delivers exceptional electrolyte wettability and ionic conductivity with porosity concentrated in the 38–41% range. Featuring 135°C thermal shutdown, TD shrinkage as low as 0.1%, and puncture strength up to 722g (20µm grade), it supports high-speed winding processes while maintaining robust mechanical integrity. Competitive wet process separator pricing makes it ideal for laboratory R&D, pilot-scale testing, and high-rate battery validation protocols.

Key Features & Advantages
  • Thermal Shutdown Safety: Full-series melting temperature at 135°C with proven shutdown characteristics across all grades (KG-PE9 to KG-PE20). During thermal runaway events, rapid pore closure blocks ion conduction, effectively mitigating internal short-circuit risks for consumer and power LIB R&D.
  • Exceptional Dimensional Stability: TD thermal shrinkage uniformly controlled at 0.1% (90°C/2h) across all thickness grades, ensuring outstanding dimensional stability under elevated temperatures and drastically reducing shrinkage-induced internal failures.
  • Scalable Mechanical Performance: As thickness increases from 9 to 20µm, puncture strength scales proportionally from 410g to a maximum of 722g (KG-PE20), offering superior mechanical protection for demanding high-speed winding applications.
  • Optimized Porosity & Wetting: Porosity concentrated within 38–41% range with Gurley values from 185 to 224 s/100ml delivers excellent electrolyte wettability and unobstructed ionic conduction, perfectly suited for high-rate charge/discharge, long-cycle battery tests, and pilot-scale production validation.

APPLICATION SCOPE: Consumer-grade LIB, power lithium-ion battery R&D testing, high-rate charge/discharge experiments, long-cycle battery validation, pilot-scale production trials, and academic research on separator thermal safety and mechanical properties.
PACKAGING: Sealed plastic bag with protective cushion pad; room temperature/low temperature dry storage, protected from sunlight, high-temperature baking, and rainwater immersion during transport.
IMPORTANT NOTICE: This separator is sensitive to ambient moisture and mechanical damage. Keep packaging sealed until use. Store in dry, cool conditions away from heat sources. Handle with clean gloves to avoid contamination that may affect electrochemical performance.

This polyethylene separator must be stored in a sealed, dry, ventilated environment at normal or low temperatures to prevent degradation. Avoid exposure to fire, heat sources, and direct sunlight during storage and transportation to maintain dimensional stability and mechanical integrity.

  • Sealed storage conditions: Store the separator in a sealed container within a normal or low temperature, dry, and ventilated environment to prevent moisture absorption and contamination.
  • Heat and fire avoidance: Keep the separator away from open flames, heat sources, and high-temperature zones to avoid melting, shrinkage, or loss of porosity.
  • Sunlight and transport protection: Shield the separator from direct sunlight, fire baking, and rain during transportation to preserve its mechanical and thermal properties.

How does the puncture strength of the 12μm wet process PE separator compare to thinner PE separators for lithium-rich manganese batteries?

The 12μm separator achieves a puncture strength of 566g, significantly higher than the 339g of the 7μm and 410g of the 9μm variants, while maintaining the same 40% porosity. This provides a favorable balance between mechanical robustness and ionic conductivity for high-voltage cathode systems.

What specific compatibility considerations exist for using this PE separator with lithium-rich manganese-based cathode chemistries?

This separator is engineered for lithium-rich manganese-based batteries, which operate at higher voltages up to 4.8V. The PE base film with a melting temperature of 135°C provides adequate thermal stability, and the low transverse heat shrinkage of 0.1% minimizes short-circuit risk during cycling. However, users should verify electrolyte wetting characteristics given the 40% porosity and 222s air permeability.

What are the critical storage and handling requirements to maintain the integrity of this 12μm PE separator?

The separator must be stored sealed in a normal or low temperature, dry, ventilated environment away from fire and heat sources. Transportation must avoid sun exposure, fire baking, and rain. The 12μm thickness makes it susceptible to mechanical damage, so the plastic sealed bag and buffer pad packaging are essential to maintain the 566g puncture strength specification.

This 12μm wet-process PE separator delivers a high puncture strength of 566g and low heat shrinkage (0.9% MD, 0.1% TD), providing mechanical robustness and dimensional stability for lithium-rich manganese-based batteries; however, its 135°C melting point and sensitivity to moisture and heat necessitate controlled storage and thermal management.

Positive

  • High puncture strength at 12μm: With a puncture strength of 566g, this separator resists penetration from electrode particles, reducing short-circuit risk during assembly and cycling.
  • Low heat shrinkage stability: Longitudinal shrinkage of 0.9% and transverse shrinkage of 0.1% minimize dimensional change under elevated temperatures, preserving electrode alignment.

Trade-offs

  • Low melting temperature limit: A melting point of 135°C restricts high-temperature applications and requires careful thermal runaway prevention in battery designs.
  • Controlled storage environment needed: The separator must be kept sealed in a cool, dry, ventilated area away from heat sources and sunlight to avoid moisture uptake and thermal degradation.
