Alumina Powder For Integrated Circuit Substrate
Factory supply 1 micron Lithium ion battery separator alumina
powder
The main component of alumina polishing powder is α-Al2O3. In addition, it contains dispersant, suspending agent, lubricant,
emulsifier and other auxiliary components. It is widely used in
machine preparation, optical processing, jewelry processing,
automobile repair and maintenance and other fields.
【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.

【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.
