Ceramic Coated Battery Separator (SEP-CER-13), PE Base Film with Double-Sided CCS Ceramic Coating, Excellent Thermal Stability for Lithium-Ion Batteries

About this item

• Double-Side Ceramic Coating for Enhanced Safety: features a double-side single-coated ceramic structure with 2 µm CCS ceramic coating on each side of a 9 µm PE base film (total thickness ~13 µm), improving thermal stability, reducing shrinkage, and enhancing puncture resistance to prevent internal short circuits at elevated temperatures
• Excellent Thermal Stability & Low Shrinkage: exhibits ≤ 3.0% MD shrinkage and ≤ 2.0% TD shrinkage (130°C/0.5h), providing superior dimensional stability compared with standard PE separators during high-temperature drying and battery operation
• High Mechanical Strength & Puncture Resistance: provides MD tensile strength of ≥ 100 MPa (typical 138-145 MPa), TD tensile strength of ≥ 100 MPa (typical 132-138 MPa), and puncture strength of ≥ 350 gf (typical 505-530 gf), ensuring reliable cell assembly and long-term cycling performance
• Optimized Porosity & Permeability: features air permeability of 150-280 sec/100cc (typical 172-202 sec/100cc) with uniform pore structure, providing efficient ionic transport pathways while maintaining mechanical integrity and electrolyte wetting performance
• Strict Quality Control & Consistent Quality: manufactured with precise thickness control (total thickness 13-14 μm), width tolerance of +0.5/-0.0 mm, and rigorous appearance inspection including no scratches, no contamination, uniform color, and no pinholes for reliable cell assembly consistency
