Battery Separator Film Alumina Powder 99.9% Purity White Color

Battery Separator Film for Lithium-ion Batteries Alumina materials

   In the structure of lithium battery, diaphragm is one of the key inner components. The performance of the diaphragm determines the interface structure and internal resistance of the battery, and directly affects the capacity, cycle and safety performance of the battery. The diaphragm with excellent performance plays an important role in improving the comprehensive performance of the battery. The main function of the diaphragm is to separate the positive and negative poles of the battery to prevent short circuit due to contact between the two poles. In addition, it also has the function of allowing electrolyte ions to pass through. The diaphragm material is non-conductive, and its physical and chemical properties have a great impact on the performance of the battery.

【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%

2. Color:white

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

【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

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.
