Micron Grade Alumina Powder Ceramic Coating Battery Separator

1 micron alumina powder for Lithium ion battery separator

In the structure of lithium batteries, the separator is one of the key inner components. The performance of the separator determines the interface structure, internal resistance, and other characteristics of the battery, directly affecting its capacity, cycling, and safety performance. A high-performance separator plays an important role in improving the overall performance of the battery. The main function of a separator is to separate the positive and negative electrodes of a battery, preventing short circuits caused by contact between the two poles. In addition, it also has the function of allowing electrolyte ions to pass through.

【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.

【Specification】

1. Chemical properties: Al₂O₃>99.9%

2. Color:white

3.PSD: D50=0.8-1.2um,D99<6um

【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.
