It is Nanometer Alumina Powder for Li-ion battery as sepertor, and ceramic diaphragm special alumina, which is a new material for lithium batteries that experts have recognized for their great potential.
The performance of Xiangrun's Nanometer Alumina Powder for Li-ion battery is comparable to imported high-purity alumina, lithium battery Pro version "security guards."
The lithium ion battery ceramic diaphragm prepared by using this product has high mechanical strength and puncture strength, has excellent high temperature resistance, and can maintain the intact shape of the diaphragm at a high temperature of 180 ° C, which can significantly improve the safety of the lithium ion battery. Especially suitable for power lithium-ion batteries.

Application:
Specially applicable to lithium battery ceramic diaphragm, it can also be widely used in fine ceramics, more than 99.5% ceramics, honeycomb ceramics; high-performance refractory materials; grinding and polishing materials.
Advantage of Nanometer Alumina Powder for Li-ion battery:
High Mechanical strength
High Puncture strength
High stability
Raise the battery safety
Alumina is high purity, and the content of harmful impurities such as silicon, iron, sodium and calcium is low, the purity of the product is high, impurities are not introduced during use, and the internal environment of the battery is not affected.
Small size and narrow & even distribution
The ultrafine alumina particle size is controlled, and the particle size distribution is concentrated, so that the lithium battery separator void is not blocked.
Good shape structure
Through the structural regulation during the production process, α-alumina grows uniformly in three-dimensional space and is microcrystalline. Through surface modification, the powder has good dispersibility. Good compatibility with electrolyte and high liquid absorption rate.
Packaging of Nanometer Alumina Powder for Li-ion battery
Inner polyethylene plastic film bag, outer layer polypropylene plastic woven bag.
20kg / bag, can also be packaged according to customer requirements
