High Temperature Resistance Nano Grade Alumina Polishing Powder
High Purity
In the field of advanced composite materials, the application of
nano alumina additives is becoming increasingly common. For
example, in the aerospace field, the addition of nano alumina
additives to high-performance polymers with extremely strict
performance requirements can ensure that materials maintain
reliable performance and excellent mechanical strength in extreme
high temperature cosmic environments, ensuring the safe operation
of spacecraft and the smooth completion of various tasks.

【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.
