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.

【Specification】

1. Chemical properties: Al₂O₃>99.9%

2. Color: white

3. PSD: D50=0.5-0.8um, D99<4um

【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.
