【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.

The presence of the alumina can significantly improve the physical and chemical properties of battery separators. The alumina coating layer may reduce or prevent dendrite puncture, lithium plating and separator shrinkage during over-heating, hence significantly increasing safety performance for a lithium ion battery
 
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.

 

1.Q:Why is aluminum oxide coating applied to battery separators?

A:The core purpose is to enhance the thermal stability and safety of the separators.
 
2. Q:How to choose the particle size and morphology of alumina?

A:Alpha type, with a median particle size (D50) typically ranging from 0.5 μm to 1.0 μ m
 
3 Q: Is it better to have a thicker ceramic coating?

A:Further improve mechanical and thermal stability, but this will result in a loss of energy density
 
4 Q: What is the minimum order quantity?.

A:The sample weighs 2kg and is provided for free, but the shipping fee needs to be paid by the buyer
