High precision Alumina for Lithium ionsbattery diaphragm

.
  The lithium-ion battery separator is a crucial component of lithium-ion batteries and the most technically challenging key internal layer in the lithium-ion battery industry chain. Its primary function is to separate the positive and negative electrodes, preventing short circuits caused by direct contact between the two poles. Additionally, it enables the passage of electrolyte ions.

【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】
 

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

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.

【Packing】 25kgs/poly-drum ,500kgs/pallet.
