Industrial Grade Micron Alumina Powder Separator Films Of Lithium Battery

Aluminum oxide ceramic coated membrane is a composite membrane made by coating nano aluminum oxide (Al ₂ O3) material on the surface of traditional polyolefin (PE/PP) base film, which combines the flexibility of organic materials and the heat resistance of inorganic materials. It is currently the core material for the safety upgrade of lithium-ion batteries.



【Application】
Power battery
New energy vehicle battery pack (essential for NCM811/NCA system)
High safety demand batteries for commercial vehicles

High end consumer electronics
Fast charging mobile phone battery (supports 6C charging)
High rate battery for unmanned aerial vehicles



【Specification】

1. Chemical properties: Al₂O₃>99%
2. Color:white
3.PSD: D50=0.8-1.2um,D99<6um

【Product features】

Lithium ion batteries with alumina separator is fabricated for safety improvement. Alumina separator is coated on electrode by a scalable and cost-effective method.Lithium ion batteries with alumina separator perform better than conventional cells.





1. Less magnetic foreign matters, stable electrical performance, low content of harmful ions;
2. High heat resistance, stable at high temperature;
3. The particle size distribution is very narrow, which can be coated with a very thin thermal insulation coating, with low thermal resistance; no small particles blocking Li + ion channel, no coarse particles scratching the film.



【Packing】 25kgs/poly-drum ,500kgs/pallet.
