1344-28-1 Alumina Powder For Lithium Ion Battery Separator Films

Generally, the surface modification of the lithium ion battery diaphragm can be used to improve the safety performance of the battery. Coating ceramic structure material on its surface can protect the interface performance, cycle performance and safety performance of the battery. The alumina ceramic membrane with excellent performance plays a vital role in improving the comprehensive performance of the battery.

【Application】

  It is mainly used for the coating material of positive and negative pole diaphragm of lithium battery, which is beneficial to the stability of the battery.

  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.
