Silica Gel Alumina Powder
Thermal conductivity of silica gel Alumina Powder
Lithium ion batteries have emerged as the most popular energy
storage system, but they pose safety issues under extreme
temperatures or in the event of a thermal runaway. Lithium ion
batteries with inorganic separators offer the advantage of safer
operation.The coated α-Al2O3 separator has a much higher resistance to temperature effects than
its polyolefin counterparts, retaining its dimensional integrity at
temperatures as high as 200ºC.
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.
1. Chemical properties: Al2O3>99.9%
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
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.
