Alumina for Lithium ion battery separator EM-series
This eliminates the possibility of a short circuit during thermal
runaway. Lithium ion batteries assembled as half-cells and full
cells with coated α-Al2O3 separator exhibit electrochemical performance comparable with that
of polyolefin separators at room temperature.
Alumina ceramics have a series of excellent properties, such as
high mechanical strength, high insulation resistance, high
hardness, wear resistance, corrosion resistance and high
temperature resistance. It is currently the most widely used and
largest production and sales of new ceramic materials in oxide
ceramics.
【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.
