Wet coating of lithium battery diaphragm alumina powder

α- Effect of alumina powder particle size on slurry processability, coating formation and performance of lithium battery with alumina powder electrode coating diaphragm. Small particles of alumina powder form a slurry with the consistency required to manufacture this electrode coated diaphragm. The alumina powder forming a uniform slurry is directly coated on the lithium electrode to form a high-quality and thin electrode support diaphragm.


【Application】
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】

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.

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.
