Power battery lithium-ion diaphragm alumina powder

In addition to expensive pricing, low driving ranges, and insufficient charging and switching infrastructure, the safety of the ion lithium power pack is a major worry for customers and experts throughout the development of new energy vehicles. This problem also has an impact on promoting the energy of the ion lithium power pack. The key to dealing with the safety of the power ups lithium ion battery is the creation of short-circuit-proof, overcharge-proof, thermal runaway-proof, combustion-proof, and non-flammable electrolytes.

【Application】
It is suitable for Lithium ion battery separator,and the battery can be used for electronic car, electronic intelligent products and energy storage products.

【Specification】

1. Chemical properties: Al₂O₃>99.9%
2. Color:white
3.PSD: D50=0.8-1.2um,D99<6um

【Product features】

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.




The alumina ceramic coating provides a skeleton for the flexible seperator, improves the wear resistance of the seperator, prevents lithium dendrite from piercing, reduces heat shrinkage, improves temperature resistance, and the pores are stable with temperature, which can effectively improve the safety performance of the 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.
