This solid electrolyte separator must be processed and stored under conditions that prevent moisture absorption and mechanical damage. The LATP coating is chemically compatible with standard lithium-ion battery electrolytes but exhibits thermal shrinkage above 130°C and requires careful handling to avoid puncturing.
- Thermal Stability Constraint: The separator must not be exposed to temperatures exceeding 130°C to prevent permanent shrinkage and structural deformation.
- Chemical Compatibility Requirement: The PE substrate and LATP coating are certified inert under ISO 10993, ensuring no adverse reactions with standard lithium-ion battery electrolytes.
- Mechanical Integrity Requirement: The separator has a puncture strength of approximately 391 gf and tensile strength over 1200 kgf/cm², requiring careful handling during lamination to avoid damaging the coating.
- Environmental Storage Condition: Store the roll in a dry, particle-free environment at room temperature to maintain porosity and prevent contamination.
- Process Alignment Requirement: The roll dimensions and flexibility are designed for use with automatic laminators such as 110mm×100mm models, requiring proper tension and alignment during cell assembly.
What performance trade-off does the single-sided LATP coating on a 12 μm PE substrate offer in terms of ion conduction versus mechanical flexibility?
The single-sided design provides stable lithium-ion conduction from the 4 μm LATP coating while maintaining excellent flexibility from the 12 μm PE substrate. This delivers a balanced performance with puncture strength of ~391 gf and tensile strengths of MD ~1310 kgf/cm² and TD ~1223 kgf/cm², ensuring mechanical integrity without sacrificing ion transport capability.
Can this 60 mm wide LATP-coated PE separator be integrated with standard automatic laminators used in pouch cell fabrication?
Yes, the product is compatible with automatic laminators such as 110mm×100mm models. Its consistent width (60±0.5 mm), total thickness (16±2 μm), and flexibility allow efficient preparation of pouch and prismatic battery cells in pilot-scale R&D without compatibility issues.
What handling precautions are necessary during high-temperature battery testing given the separator's thermal shrinkage properties?
The separator exhibits low thermal shrinkage of MD ~1.5% and TD ~0.7% at 130°C for 1 hour drying, minimizing deformation. To preserve structural integrity, ensure uniform heating and proper tension in the laminator; the material complies with IEC 61960 safety standards, making it suitable for high-temperature battery safety verification.
The Atomfair Single-sided LATP-Coated PE Separator Roll offers a flexible solid electrolyte with good thermal stability and mechanical properties, suitable for pouch and prismatic cell R&D. However, the roll-only format and single-sided coating require careful handling and orientation during cell assembly.
Positive
- Balanced flexibility and ion conductivity: The PE substrate provides excellent flexibility for easy processing, while the LATP coating ensures stable lithium-ion conduction, critical for solid electrolyte applications in battery R&D.
- Superior thermal stability: With ultra-low thermal shrinkage at 130°C, the separator maintains structural integrity under high-temperature testing, significantly enhancing battery safety during R&D experiments.
Trade-offs
- Roll-only sales format: Exclusively available in roll form, requiring in-house cutting to desired dimensions for pouch or prismatic cell assembly, which adds a preprocessing step and potential for dimensional variability.
- Single-sided LATP coating: The LATP coating is applied only on one side of the PE substrate, necessitating careful orientation during cell stacking to ensure the conductive side faces the appropriate electrode, increasing assembly complexity.
