Battery Grade CAS 1344-28-1 White Alumina Powder For Electronic Car

  
  Lithium ion battery separator is a porous thin film with evenly distributed micropores, located between the positive and negative electrode materials of lithium batteries. It plays a key role in preventing direct contact between the positive and negative electrodes, preventing battery short circuits, and transferring ions. It is a critical material for ensuring battery safety and affecting battery performance.
 
【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=0.5-0.8um,D99<4um

【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.

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