99.9% Purity 0.8 Micron Alumina Powder For separator of lithium
battery
Lithium ion batteries with an inorganic separator offer improved
safety and enhanced reliability. an aluminium oxide Al2O3 or also called alumina) layer in lithium ion-batteries is
typically deposited on top of the separator membrane to enhance its
thermal properties, enabling it to preserve its mechanical
integrity at temperatures up to 200 • C The performance of
lithium-ion batteries with coated alumina separator foils is the
same at room temperature as that of those with a polymer separator.
【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.
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.
