Core Functional Advantages
- Symmetrical Dual-coating Design
The double-sided LATP coating ensures uniform ion conduction across the separator, eliminating performance discrepancies between two sides and enhancing the consistency of battery R&D test data. - Balanced Flexibility and Stability
The PE substrate provides excellent flexibility for easy processing and handling, while the LATP coating maintains structural stability even under high-temperature testing conditions, avoiding deformation and ensuring reliable electrode isolation. - Strong Process Compatibility
With consistent dimensions and flexibility, the separator is fully compatible with mainstream automatic laminators (e.g., MSK-111A-ES, 110mm*100mm), enabling efficient preparation of pouch cells and prismatic battery cells for laboratory research.
Application Scenarios
This high-performance solid electrolyte separator is tailored specifically for lithium-ion battery R&D scenarios, ideal for the following applications:
- Lithium-ion battery R&D laboratories, providing core materials with balanced ionic conductivity and structural stability for new battery technology development.
- Preparation of pouch and prismatic battery cells using automatic laminating equipment, supporting small-batch experimental production and performance verification.
- Research projects focusing on solid-state electrolyte materials, where stable ion conduction and processability are critical evaluation criteria.
Quality Compliance
- Raw materials (PE substrate, LATP powder) comply with ISO 10993 chemical inertness standards, ensuring no adverse reactions with lithium-ion battery electrolytes and electrode materials.
- Mechanical performance testing (tensile strength, puncture strength) adheres to ASTM D882 and ASTM D726 international protocols, guaranteeing batch-to-batch consistency.
- Thermal shrinkage testing meets IEC 61960 battery component safety requirements, aligning with global lithium-ion battery R&D standards.
- Packaging conforms to international shipping regulations, preventing separator contamination and damage during long-distance transportation to global R&D facilities.
