LATP Solid-State Electrolyte Coated Separator (SEP-LATP-13), Double-Sided Single-Coated Ceramic Composite Separator for Li-Ion Batteries

About this item

• Dual-Side Composite Coating: features a composite coating system with 2 µm Al₂O₃ (ceramic) on one side and 2 µm LATP (oxide solid-state electrolyte) on the other side of a 9 µm PE base film (total thickness ~13.7 µm); LATP coating provides lithium-ion conductivity while ceramic coating enhances thermal stability and safety
• Enhanced Thermal Stability & Safety: ceramic coating improves thermal shrinkage resistance with 130°C x 1 h MD shrinkage of 1.7% and TD shrinkage of 0.7%, effectively reducing internal short circuit risks caused by separator shrinkage at elevated temperatures
• Low Coating Weight & High Energy Density: LATP coating provides lower grammage compared with Al₂O₃ coatings of the same thickness, minimizing added mass while delivering lithium-ion conductivity for high-energy-density battery designs
• High Strength & Processability: provides high mechanical strength with MD tensile strength of 2038 Kgf/cm², TD tensile strength of 1817 Kgf/cm², puncture strength of 503 gf, and air permeability of 167 sec/100 ml, ensuring reliable cell assembly and long-term cycling performance
• Battery Application Compatibility: suitable for liquid lithium-ion batteries, hybrid solid-liquid batteries, and semi-solid-state batteries (coin cells and pouch cells); LATP coating side should face the cathode in lithium metal battery configurations; not recommended for all-solid-state batteries or sodium batteries
