Core Functional Advantages
- Synergistic Coating Performance
The Al2O3 coating enhances high-temperature stability and short-circuit prevention, while the LATP layer ensures efficient lithium-ion conduction. This dual-layer design achieves an optimal balance between battery safety and electrochemical performance. - Outstanding Mechanical Strength
With high puncture resistance and balanced MD/TD tensile strength, the separator withstands the stress of battery cell assembly and testing, avoiding structural damage and ensuring consistent performance. - Low Thermal Shrinkage
Ultra-low thermal shrinkage at 130? maintains structural integrity under high-temperature testing conditions, eliminating the risk of electrode contact and significantly improving battery safety during R&D experiments. - Strong Process Compatibility
Excellent flexibility enables seamless compatibility with automatic laminators (e.g., MSK-111A-ES, 110mm*100mm), supporting efficient preparation of pouch and prismatic battery cells for R&D.
Application Scenarios
This high-performance solid electrolyte separator is specifically tailored for lithium-ion battery research and development, ideal for the following scenarios:
- Lithium-ion battery R&D laboratories, providing core materials that balance safety and ion conductivity for new battery technology development.
- Preparation of pouch and prismatic battery cells using automatic laminating equipment in pilot-scale R&D projects.
- High-temperature performance testing and safety verification of lithium-ion batteries, ensuring reliable experimental data.
