This separator roll requires controlled temperature and mechanical handling to maintain integrity. Exceeding rated thermal or mechanical limits may cause irreversible damage.
- Thermal Exposure Limits: The separator must not be exposed to temperatures at or above 130°C for extended periods to avoid shrinkage and structural changes.
- Mechanical Load Limits: Applied forces must remain below the puncture strength of 395gf and tensile strengths of MD 1200 Kgf/cm² and TD 1460 Kgf/cm² to prevent tearing or puncturing.
How does the double-sided LATP coating thickness of 2 μm per side affect the separator's ionic conduction and mechanical puncture resistance?
The 2 μm LATP coating per side provides uniform, continuous ion-conductive pathways while maintaining the flexibility of the 12 μm PE substrate. Despite the thin ceramic layers, puncture strength remains ≥395 gf, ensuring robust electrode isolation without sacrificing the mechanical integrity needed for automated lamination.
What are the temperature constraints for using this LATP-coated PE separator in battery testing?
The separator is tested to maintain dimensional stability up to 130°C for 1 hour, with thermal shrinkage ≤2% in the machine direction and ≤1% in the transverse direction. Prolonged exposure above this limit will cause PE substrate deformation and loss of electrode isolation, limiting its use to moderate-temperature solid-state electrolyte evaluations.
What handling and equipment infrastructure is required to process the 100 m roll of LATP-coated PE separator?
The separator is supplied in a roll format (60 ±0.5 mm width, 100 m length, 16×8×8 in outer packaging) and is fully compatible with automatic laminators such as MSK-111A-ES (110 mm×100 mm). Handling requires a clean, dry environment and automated unwinding to prevent creasing or cracking of the 2 μm LATP coatings; manual cutting must be performed with sharp, clean tools.
This double-sided LATP-coated PE separator provides a unique combination of mechanical flexibility and thermal stability for battery R&D, with symmetrical coating ensuring uniform ion conduction. However, its exclusive roll format and measured thermal shrinkage of up to 2% at 130°C introduce handling and dimensional considerations during cell assembly.
Positive
- Symmetrical Dual-Coating Design: Both sides are uniformly coated with LATP, eliminating ion conduction discrepancies between faces and improving the consistency of battery test data.
- Flexibility and Thermal Balance: The PE substrate provides excellent flexibility for easy processing, while the LATP coating maintains structural stability under high-temperature testing, preventing deformation and ensuring reliable electrode isolation.
Trade-offs
- Roll-Only Sales Form: The separator is supplied exclusively in roll form, requiring additional cutting and handling steps when preparing small-scale pouch or prismatic cells, which may increase manual labor and risk of edge damage.
- Thermal Shrinkage at 130°C: With MD shrinkage up to 2% and TD up to 1% after 1 hour at 130°C, dimensional changes must be accounted for in cell assembly processes that involve elevated temperatures, potentially affecting electrode alignment.
