Product Description

High precision Alumina for Lithium ionsbattery diaphragm

  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.It is mainly used in tableware industry, jewelry industry, auto parts, optical lens, machine electrical accessories and other industries that need surface treatment.The calcination temperature of alumina polishing powder should be high, generally above 1600, so as to ensure that the product has good hardness.

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


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


Factory supply 1 micron Lithium ion battery separator alumina powder 2

The alumina ceramic coating provides a skeleton for the flexible seperator, improves the wear resistance of the seperator, prevents lithium dendrite from piercing, reduces heat shrinkage, improves temperature resistance, and the pores are stable with temperature, which can effectively improve the safety performance of the 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.
